You Only Live Thrice - Very randomly. I got this achievement only after 80 hours of gameplay (And I needed to kill Skeleton 5 times (!) in a row). This achievement include Skeleton, Giant Skeleton, Skeleton Warrior, Lich, Arch-Lich and Ghoul.

That Was Lucky! - To get this achievement, you need to buy and upgrade to epic Glyphic items. For all set you can get +24 spell resist, and if you upgrade morale, then at 50 lvl you may have almost 60% resistance. Crushing Kill have Yeti and Irom Golem, Subjugate - Gorgon. You only need to give them get 65 red mana and let use that spells.

Cheating AI - I got this achievement in Tournament mode when after passing the enemy I had 5 hp and next enemy had first turn with skulls - ez.


Have You Killed Him Yet? - You can get this achievement by 50 lvl mage with Mana Siphon or Assassin with Weaken. At the beginning you can start kill him (he will heal himself with icy breath) and use mana siphon (or weaken), when he get a lot of red mana. Also you can take healing poison (at 50 lvl he have 124% critical hit).

We Don't Need No Water - Very randomly and hard to get, but it`s possible. Before it, take off all armor and try not to combine blue gems - only red. You must die from them to get achievement.

You're Doing It Wrong - Good class to get it - Barbarian. At the beginning you must kill troll with 5hp regen every turn and barbarian can kill him with Tribal mark without using the torch. You will be able to use only 2 items - Hammer of Righteousness and Molten Metal. That`s all. No bullfighter cap, no water bucket and torches. And don`t use backstab as assassin.

Don`t use first chests. Wait at least untill 25-30 lvl and then you can get back to them - you`ll get some better and more expensive items.
And if you don`t like what you`ll get from chest, just use "Quit game" and try again untill you get something good or expensive.
List of expensive items at high levels:

• Assassin`s poisons (Manticore and Wyvern) and nightblades.
  
  
  
  
  
  
  
• Templar`s armor (every part), shields and holy swords.
  
  
  
  
  
  
• Some of Barbarian`s hammers.
  
  
  
  
  
  
• Scalemail armor (every part)
  
  
  
  
  
  
• Kite shield, Witch Blade, Flintlock Pistol, Major Healing Poison (especially Legendary)
  
  
  
  
  

• Don`t play searching minigames in rooms with traps. Just pass through them and disarm (save some time). Use it only in rooms with hidden treasures (when after passing the room without hitting the trap. Exception - corridor before "Skullbreaker" ogre - there is trap).
  
  
• When you play as Assassin you can hit enemy with 8x damage strikes with Stealth + Disarm + Blackjack + Shadow Strike (16 damage for 1 stone).
  
  
• Also Backstab ignore Shadow curse.
  
  
• About Shiels critical. It means that when using a shield, you can get it double protection (Same as double damage with weapon).
  
  
  
• About prefixes (rarity increases by the end of the list):
  Ancient - bonus defence.
  Hellforged - bonus weapon critical hit.
  Glyphic - bonus spell resistance.
  Runic - bonus shield critical chance.
  Draconic - bonus blocking damage reduction.
  Daemonic - bonus skull damage - the rarest items which can appear after 30 lvl at traders or can be found in chests. First Daemonic item is pendant after killing first possessed leader.
  
  That`s all for now :)
