For information on these topics for all my mods as a whole, please refer to my mod thread on the Terraria Community Forums[forums.terraria.org]. The information there is also a little more detailed!



Multiplayer compatibility:
Net-code is in place to keep XP and levels synced when dropping or otherwise transferring items. However, players should ensure they personally craft their weapons apply Runes to their weapons themselves, as there are still some issues; if another player applies a Rune to a weapon or crafts that weapon, and gives it to someone else, that weapon will inexplicably lose its ability to gain XP if the player dies or leaves/rejoins the game.

Mod compatibility:
Should be fine with any other mod, though it cannot handle modded rarities and will default them to the highest possible Rune requirement (Use Ethereal Runes to manually balance). Has cross-mod features with my other mod, 'Weapon Augments', in which your weapons can gain extra slots for Augments as they level up.
Exception; there is an odd issue with Terraria Overhaul, in which using both this mod and Overhaul may cause your game to start heavily lagging and desyncing after a while; proceed with caution when attempting to use both at once.


Known Issues:
Minions may sometimes seemingly stop earning XP and Levels, even though the game announces them leveling up.
To minimize the chance of this bug occurring, make sure to use your summon staves from the hotbar, NOT while held in your cursor. Depending on their nature QoL mods that automate minion summoning can also trigger this bug.
First try dismissing the summons and re-summoning them (using the technique described above). If that doesn't work, next try disabling the leveling (Via. a Blank Rune) and re-enabling it with a new Rune. If all else fails, unfortunately you'll have to settle for a clean staff/weapon.
In either case I HIGHLY suggest using a mod like Cheat Sheet or similar to give yourself the necessary items (Ex: A new copy of the weapon, Rune(s), XP orbs) to re-do lost progress, so as to minimize inconvenience.

Reporting Bugs:
If you desire to report a bug, first confirm it can be recreated; meaning performing the same actions leading up to the bug will cause it to occur again. This makes it much easier for the modder (me) to observe the anomaly firsthand. Second, also determine/confirm the suspect mod that is causing the problem; if a bug only occurs when multiple mods are active, it is likely an incompatibility problem. In that case, please also report the bug to the other mod(s)’ owner(s).
When reporting, I strongly prefer that you post an issue on my GitHub repository for my mods' tmod files; this is more organized than other methods and also allows others to see and potentially offer solutions to the issue. You can find that repository here[github.com].
Finally, I’d like to leave a reminder here that I am the sole maintainer of all my mods; if you report a bug, do not expect instant gratification! It is very likely that I’m busy releasing, and/or developing other mods and thus it will take a long time to get around to your bug. My condolences in advance…

State of development?:
The mod is now in a finished state, and for the foreseeable future I have no further plans for it.
