Actions:
Move action to put away my greatsword
Free Action activate Whirling Frenzy
Free action 5' step to the right (occupying the square underneath Mercutio)
Standard action Dimension Door to the square 10' above Paleface (Blink Shirt ability). Since I'm hurling myself down on him from at least 5', this should activate Battle Jump, allowing this to count as a Charge attack, which would in turn activate Pounce.
With my first attack from the charge, I will attempt to start a grapple. I don't have Improved Grapple, so this provokes an Attack of Opportunity. If he hits my AC 20 (22 - 2 charge) and deals damage, my grapple attempt fails. I'll go ahead and proceed anyway though.
Touch Attack to get a hold:
Rolled 1d20+12 : 17 + 12, total 29
Opposed Grapple check:
Rolled 1d20+22 : 6 + 22, total 28
Grapple Math: 4 BAB + 4 Str + 4 Size (Battle Jump) + 10 Girallon Arms = 22
The rest of my attacks will depend on whether this first one succeeds or fails, so I'll post again once we find out
