This page covers a DPS-focused strategy for Guarm in Normal and Heroic Trial of Valor. While it's tailored for DPS, other roles may also find the information useful. The information below is based on the live dungeon journal as well as available information from the PTR. Once the raid goes live, this guide will be updated. If you have any suggestions or feedback, you can leave a comment below or tweet @VirendraDG.
Guarm's mechanics all require precise positioning and raid awareness. He has more one-shot mechanics than other bosses, and on top of that has a strict 4 minute enrage timer. This fight is only one phase.
