bard song works for 10 rounds no matter what I think (yeah just checked, just in case
)
anyway I don't c why ppl would want to go melee or try hitting, tho with such low hp it might work, because I think the best would be using a caster wether druid cleric sorc or wizard they're all good enough. A good lvl 1 will maybe get 4 ford (a guess) and even lower will saves, so a very efficient spell can be cast, sleep (will save: 10 + lvl 1 spell + modifier), only a lucky roll would save the opponent. Don't know if the cleric gets that spell, but he can get the domain where he gets better summons. My friend played 2 vs 1 (about lvl 5) and he owned them both by casting a summon and just buffing it, and if it dies..... do it again
I won't bother trying to make a lvl 1 because I don't care, but think about those tactics hehe
