How to unlock the Mastermind achievement in Dungeon Defenders - Definitive Guide
The Master Strategist award is given for using only Tower Defenses throughout the entire duration of the level. Any attack by Weapons or Pets will negate the trophy. This must be done for every Campaign Level, including Glitterhelm Caverns.
You may switch to another Hero at anytime, as long as that Hero does not perform any attacks or has a Pet that can attack.
You can see if you have achieved the award at the end of the round by checking the Hero tab at the Crystal and pressing . You can also check it at the Crystal in the Tavern.
