Echo of Varshan

Initiate · 1× Lair Key

Fight

• Resist: Armour and Shadow Resistance. Kit is Shadow / Physical.
• Tentacles: Melee tendrils and putrid projectiles. Step behind him.
• Putrid Dance: Pink floor tiles explode. Leave the highlighted tiles. Three patterns.
• Summon Malignance: Three Malignant minions. Kill the one he channels toward before he absorbs it, or he gains a dangerous buff. On Season 8+ those become seeking projectiles.
