The spider recoils from the two solid hits but stabs at the bison once again before retreating. The jab penetrates the tough hide (-3hp) and the bison roars angrily as poison courses through its veins (-5str). As the vermin leaves, disappearing from sight, the bison may give it a goodbye kiss.
Torin's turn, please start with resolving the AOO. Don't forget the lower strength.
Will update roll20 later, the spider retreated to the corner, up to the ceiling if alive after the aoo. A feeble attempt since the bison can reach it there as well...
The herd mammal gores the vermin and tramples through its very dead body. Torin follows and pushes the button.As the doór opens another large spider lunges forward, towards the bison, jabbing through just enough to hurt (-1hp)
Continuing to orate on dwarven bravery, Portho moves as far as he can and still be able to acrt this round. At the end of his movement he leans out awkwardly past the corner to shoot at the spider that had been trapped behind the far door.
[rolling d20+8+1-4-4 shortbow attack, firing around the corner, into melee (9)+8+1-4-4= 10]
His shot gues wide. As he took the shot he frowned at the carelessness with which the dwarf charged ahead to open the next door before the first foe was even vanquished.
Portho continues the stirring ovation while he takes a 5' step to the north and then takes careful aim with his bow. As the bison and spider jockey for position Portho waits for his opening, and then lets the arrow fly.
