Dungeon Defenders patch 10.8.1 adjusts balance and adds achievement

Patch 10.8.1 for Dungeon Defenders is now live. It sets the Mortar Damage Reduction on Tinkerer's Workshop for non-boss EVs to 40%, adds a kill volume to a crystal with collision on Etheria's Primordial Palm's east island and adds music to that map, hopefully fixes Tavern Incursion gas immune enemies not having ruthless materials applied, and adds the Infested Waters in-game achievement and trophy. For Etheria!
