Rowan's Trip attack: 28.
Rowan's Strength check: 27 (including +4 from Improved Trip)
Grimlock's Strength check: 14
Rowan handily topples the grimlock, and then deftly slashes it while it is down:
Attack: 28
Damage: 13
The grimlock is bleeding, but only continues to growl and shout more fiercely.
From the back, grimlock #4 is also making incomprehensible noises, but in comprehensible way. Aside from waving its arms in a way that seem to be gesturing at the wall of the cave, it doesn't move anywhere.
Grimlock #5 charges straight at Rowan, waving a battleaxe. Rowan may take an attack of opportunity before his enemy reaches him (the joys of weapon reach).
