Poor Vordakai =(I am currently fighting 2 Marilith and a respawning Derakni who are absolutely decimating my party at the same level/chapter/part of the game where I was pubstomping Vordekai dungeon without a single reloadSummons are such a game-changer in those early game fights. Can't be overstated. Just having walls of hit points to screen your characters can by itself reduce tough encounters to facerolls.
Even with maximum vanilla stats and improved stats from mods, he still lasted a few rounds tops in my last playthrough. Sad times.
