The capstone
Apex Mutation costs 3 points and gives: Poison all enemies for 4% of their HP each round; 5% of damage dealt heals you; Regenerate 2% max HP each combat round; +10% Max HP. To take it you need Plague Carrier at rank 3, Bloodsurge at rank 3, and 25 points spent in the tree. Plan your path backwards from the capstone: spend your early points on the talents it requires, then fill in the rest.
Pairs well with
Mutagen works best alongside Berserker and Juggernaut. Berserker adds more lifesteal and damage when you are low, and Juggernaut offsets the HP you lose to the Mutated Anomaly background.
