Most of the times poison builds are lacking something.. Aoe, single target, tankiness… But this one i think is the golden core of what poison can do. It’s cheap, tanky, fast, and very effective.
Pestilent Strike and Pathfinder have glorious synergy. Pestilent Strike has innate poison proliferation, and Nature’s Reprisal is literally a poison aoe as well. So you don’t need Bino’s or any other poison “gimmicks” to spread poison. With natural Pathfinder’s flask uptime and ailment immunity Coralito’s always working giving over 30% of damage permanently. Not to mention astronomical amount of evasion transformed into armour, making you very tanky and able to facetank a lot of bosses.
