(My first self-made build)
+Additional 240% melee crit at full combo
+250% damage reduction
+Capped strenght (180% max on parasite link)
+Good range for grouping eniemies (larva)
+Survivability and damage
+Cheap(No prime mods)
If you want additional crit chance mod you can take [Gladiator Finesse], you get 360% crit chance(1010% if using blood rush), 900% without Finesse.
Game plan on steel mode: Group enemies(larva) - stack passive with 1 ability (50 stacks atleast) - Group eniemies again- Stack your melee weapon combo to max (12 by default) - While fightning: Use parasite Link for survivability - Use 4 ability for healing and stuns
