• This guide will simply state whether or not an ability has any effect on a Demolyst. This is not a "what frame is best for Disruption" guide. I will offer some opinions, but ultimately that's all it is. You decide how you want to play.
  
• I do not cover any sort of weapons here, nor any synergies between weapons and frame abilities, nor compare them.
  
• I will mention the bugs I find during the making of this guide or any glaring issues or inconsistencies between events that take place. If I mention any game-changing bugs or exploits it is not because I agree with their usage or encourage it. I want people to simply be aware, not abuse them.

• The format is as follows: Ability Name (Cycled Choice, if applicable): Does the ability affect Demolysts in any way? Followed by how it affects them if it does.
  
• I will italicize effects that I find worth noting, such as long-lasting stuns.
  
• Things that do not directly affect Demolysts, such as personal damage boosts or non-damaging abilities will be labeled simply as "Personal buff." There will be some exceptions, such as exceptionally strong damage buffs that work on Demolysts, but that's all.
  
• All augments will be listed, but unless they directly modify something about the original ability that may change how it affects Demolysts, it will simply be listed as a "Personal buff."

Much of this information I obtained by going in-game, one frame at a time, and doing an entire round of Disruption while checking out the frame's various abilities on all five Demolysts, and some Demolishers. I do this because the Simulacrum cannot account for any changes in their pathing, as they have different priorities in Disruption. For that reason, it takes a while to update things and information may be incorrect, but if that's the case just comment or DM me.

For those who may not know, Demolysts are a new sort of enemy added in the new Disruption gamemode.

Demolysts spawn once a key has been placed into one of the four available conduits, and its sole goal is to destroy it. Only one spawns on the map (as far as I know) per conduit activated, and you can tell where it's coming from by its signature beeping sound, which you can use to track its location down before it gets close to your conduit. Destroy it, and that conduit's round is over.

These guys are a little different than the other enemies in a few regards (besides the beeping):

• They're much tougher, you won't be killing these guys just as easily as every other enemy, and will get stronger with each completed Disruption round. They're still one-shottable for a while though, don't worry.
  
• They are not immune to status. Some guides are saying they either are or use an ability that makes them immune to status, but that is not the case. The only Demolyst that becomes immune to anything is the Demolyst Moa. After most of its health is depleted, it will fire its cannon at the ground and become immune to any and all abilities while also healing itself.
  
• These are not like the amalgams you fight normally all around the map, these are special enemies.
  
• They emit a nullifying pulse every 1-2 seconds. This is not a nullifier bubble like we are used to the corpus having. Meaning you can get in close, but stay too close and their bubble will turn off abilities that are currently working on you, as well as any abilities you might be using or have placed on the Demolyst. Procs stay, abilities don't.
  
• They prioritize the node above all else, and will not stop just because you're in the way. I only know of a single ability that makes them stop everything they are doing without actively stunning or hurting them, and that being Gara's Spectrorage.
  
• They cannot be stunned out of their final charge attack that destroys conduits. This is more of a guess on my end, as I have had no luck with weapons nor frames in this.

Abilities:

• Shuriken: YES It deals damage to Demolysts.
  
• Smoke Screen: NO Personal buff. Removed by nullifying pulse.
  
• Teleport: YES No, you cannot one-shot Demolysts with Fatal Teleport. Even if you have a dagger with Covert Lethality equipped, this will not kill them. In fact, this deals no damage to them. All it does is stun the Demolyst for 1-2 seconds (tested with Fatal Teleport). You do not play any backstabbing animation.
  
• Blade Storm: YES You can tag Demolysts, but be quick as all the tags get removed with their pulses.

Augments:

• Seeking Shurikin: YES It has no new effect on Demolysts, but it does strip Demolisher armor.

• Tectonic Fracture: NO Personal buff.

Abilities:

• Sonic Boom: YES Deals damage. In the Simulacrum, it moves them away.
  
• Sonar: YES Demolysts can have Sonar applied on them, however, all stacks will disappear once they do their nullifying pulse.
  
• Silence: NO No effect.
  
• Sound Quake: YES Deals damage, but does not stun them. In the Simulacrum, they are immune to the damage and stun.

Augments:

• Sonic Fracture: YES Does nothing to Demolists, but it stips Demolisher armor.

• Energy Transfer: NO Personal buff.

Abilities:

• Slash Dash: YES Deals damage.

• Avalanche: YES Deals damage, but does not stun.

Augments:

• Freeze Force: NO Personal buff.
  
• Ice Wave Impedance: YES The demolyst is slowed by the trail and while the nullify pulse does clear the effect, it does not remove the trail, causing it to immediately be re-slowed as long as it is on a trail (Credit: Marcach).
  
• Chilling Globe:
  
• Icy Avalanche:

Abilities:

• Shattered Lash: YES Deals damage.
  
• Splinter Storm: YES Deals damage.
  
• Spectrorage: YES Demolysts stop everything they are doing. With max range, their bubble is too small to take down the mirrors, and they can potentially be stunned until the timer on the ability runs out. Recasting gives varying results depending on how far the AI will decide to walk.
  
• Mass Vitrify: YES Stops them until their nullifying bubble breaks the walls. Recasting doesn't affect them.

Augments:

Augments:

• Dessication's Curse:
  
• Elemental Sandstorm:
  
• Negation Swarm: NO Personal buff.

Abilities:

• Quiver: I looked specifically into the Noise and Sleep arrows, since the others fit into my "personal buff" category. Noise had no effect on them. Sleep arrows stun Demolysts until their nullifying bubble frees them.

• Prowl: NO Cannot be pickpocketed.

• Rift Surge: NO Has no effect and also cannot spread to Demolysts from other enemies.
  
• Cataclysm: YES Entering the cataclysm hurts Demolysts, but does not stop them and Stasis doesn't stop them either. The nullifying pulse destroys the bubble.

Augments:

• Rift Haven: NO Personal buff.
  
• Rift Torrent: NO Personal buff. Not recommended to work around this augment for Demolysts, as the window to take advantage of the damage buff is too small and not worth your time.
  
• Cataclysmic Continuum: NO Personal buff.

Abilities:

• Decoy: YES(?) Decoy targets the Demolyst, but it doesn't seem to be a priority target.
  
• Invisibility: NO Personal buff.

Augments:

• Savior Decoy: NO Personal buff.
  
• Hushed Invisibility: NO Personal buff.
  
• Safeguard Switch: NO Personal buff.
  
• Irradiating Disarm:

Oh boy. This one can potentially break the Demolyst AI if you're not careful. As long as you're on even ground and an area you can safely walk on, feel free to abuse the heck out of this. However, if you do choose to abuse it and teleport the Demolyst into an area inaccessible by normal means or try to despawn it by sending it off the map, one of a few things will happen that I have observed:

1. The Demolyst will get stuck in the terrain, allowing you an easy kill on it, or simply allow the timer to run out for an easy node completion.
   
2. The Demolyst will clip into the environment and start walking in a straight line toward either the objective or the nearest walkable surface for it, I can't tell. You will not be able to kill it in this time unless you have an ability that can target it through the floor. It usually pops out near the objective.
   
3. The Demolyst will do the same as above, but once it comes out it will completely lose track of its objective and run around aimlessly, but will still not attack you.

An example of when a Demolyst started walking through the terrain.

An example of it getting stuck. It remained there the whole time and could never find a way out.

Abilities:

• Enthrall: YES/NO See notes below.
  
• Mesmer Skin: YES/NO See notes below.
  
• Reave: YES Deals damage.
  
• Danse Macabre: YES Deals damage.

Augments:

• Thrall Pact: NO Personal buff.
  
• Blindign Reave:

Revenant seems to be bugged, in that one of his abilities has effects on a few types of Demolysts and no effects on others. Normally, Enthrall and Mesmer skin have no direct or indirect effects on Demolysts, as they cannot be Enthralled, will not attack Enthralled enemies, and will not attack you.
BUT- when you Enthrall an enemy within a certain range of the Demolyst and in its line of sight, there is a chance it will abandon everything it was doing and either attack the Enthralled enemy or bug out and stand in place.
Once they react to Enthralled enemies, no matter if they die or the timer runs out, the Demolyst will now no longer pursue its original objective of destroying a conduit and will attack you and your allies. At this point, Mesmer Skin becomes useful against them, as they do get stunned when they attack you. The stun lasts until their nullifying bubble frees them of the status, and they will continue to attack you like any other enemy and they do not seem to despawn.
I cannot confirm nor deny if this works on all Demolysts, but I have been able to successfully replicate this bug of the Demolyst Heqets, MOAs, and Machinists. I had no luck with Satyrs due to their speed and difficulty timing enemy Enthralls to get a result.

A Demolyst Machinist now doing absolutely nothing in a hallway after attacking my darling Enthralled MOA. :(

This section is for things I noticed across the board with more than one frame or type of ability. And overall any bugs I might find along the way.

• Certain abilities that proc some sort of effect on the Demolyst, such as sleep or stun, do not work the same way across the board. As examples, Inaros's Desiccation versus Excalibur's Radial Blind. Both leave a sort of stunning effect on the Demolyst, and both are removed by the Demolyst's natural nullifying bubble. However, Desiccation can be used multiple times for the same results, while Radial blind can only stun them on the first hit. I'm not entirely sure why this is or if this is even a bug, but feels really inconsistent to the point that I felt it was necessary to even make this guide in the first place. As far as status-proccing abilities go, the status remains through the nullifying bubble pulse. An example of that being Equinox's Day form's Maim.
  
• Some abilities that may be similar in nature might have completely different results. Two abilities that work to either incapacitate or stun enemies might work completely differently on Demolysts. One might just slow down, while the other doesn't work at all, or only works the first time? Like... What? Why? Why do some abilities like Vauban's Bastille and Vortex end up slowing the enemy... But only on the first use? Zephyr and Hydroid, who both have very similar 4th abilities, have completely different results when using them.

• Also completely unrelated, and not sure if this counts as a spoiler but better safe than sorry. If you don't know what an Operator is, this isn't something you'll care to read about: When you come back from a mission and you are standing up as your Warframe in your Orbiter, if you press 5 to go into Operator, it summons your Operator makes you perform one of your attacks while your frame turns into an uncolored Excalibur and slumps on the floor. The only way to get out of this bug is to open the menu and either go into a mission/ Relay, or restart the game. Not sure how long this one has been around for. Can be replicated every single time.
