For those who don't know, Nethril's main attack is 3 hits with chances to put poison on the target.  However, when I put him on auto on the boss fight, he also uses his A2 and A3.  Is this a bug in the AI, as from what I understood, his poisons do FAR more damage than his A2 and A3 would for a boss?  Wondering if he does that because getting the TM of the boss reduced and/or slowed down by his other two attacks is worthwhile too, or if I should just cast his A1 manually the whole fight?  I could test it, but with how much overall damage can vary due to RNG, I don't think I would get an accurate estimate.
