As long as I can remember it's the taunt component that's autohit which is all that mattered to me.
He will honor his words; he will definitely carry out his actions. What he promises he will fulfill. He does not care about his bodily self, putting his life and death aside to come forward for another's troubled besiegement. He does not boast about his ability, or shamelessly extol his own virtues. - Sima Qian.
The taunt, immobilize, and slow are autohit, but the damage portion requires a tohit check to hit.
Do I recall correctly that this power used to automatically hit? Is the accuracy necessary for all effects now, or just the damage?
Goodbye may seem forever
Farewell is like the end
But in my heart's the memory
And there you'll always be
