So I was rolling a new game, testing my mods. Playing on legend. Went into the first mission, got Syn. I had no real issues with the Snipers and their pistols, but what I later found out was there was an infiltrator there. I had to be practically standing on it just to see it. But the poison damage it dealt was ridiculous. In one turn it shot my Heavy several times, dealing negligible damage, but stacked up almost 400 poison! So of course the start of my turn, the Heavy gets one-shot by poison.
I’ve never used poison weapons because the damage it deals is usually garbage. I’ve never seen a poison weapon stack up so much so quickly. Unless I just found a bug or something, Poison is now the #1 OP damage to me. Bypasses armor, one-shots at the start of their turn. In the famous words of Ryan George, super easy, barely an inconvenience.
