How to unlock the Mystical Firecrackers achievement in Army of Ruin - Definitive Guide
Ice tear is a Trinket,you get it by upgrading Toxic Stench to level 5 on Cracier 1,no ruin needed
Ice Tear will need to be unlocked first (refer to Ice Tear (10G)) but I find it pretty solid for mobs. You'll need to get lucky to have it show up as an option, but then since this achievement doesn't require you to finish the stage, you could just focus on experience gain and max out this trinket.
