Torokk's glaive of course hit with a roll like that; and caused a deep wound in the spider, it's now badly hurt.
that's all the player actions, now for the spider's turn!
it takes a 5 ft step forward into melee range and viciously bites at Lars!
(1d20+4)[12]
(1d6)[1]
the spider's bite fails to penetrate Lars's chain shirt!
It is now the party's turn again, I rather doubt the spider will survive this turn.
