I wanted to try my bard in doom but I am a little confused. If I wanted to target a rotting corpse or lich lord (both undead) onto the dark father (demon), would I want an undead instrument? I know there is lolo's lute but I only have one and it is almost out of charges (and I can not find any others). So what chances of success do I have when I use an Undead or Demon instrument? The barding calculator is not working with slayer and exceptional nor do I know if the baselines are correct, does anyone know the correct answer?
