I attack! Assuming this functions like a surprise round, partial charge! Blow one of my uses of Improved Burst, setting my speed to 70 for the next three rounds, power attacking for 2 (full), two handing my blade.
Attack roll:
1d20+7=18. I want to make sure it hits, so blowing an action point as well:
1d6=3. 21 total.
If it hits, damage:
1d6+6=10.
Initiative for subsequent rounds, if needed:
1d20+4=23.
Let me know if I need a miss chance roll, or if you'll be rolling it instead. EDIT: Miss chance:
1d100=39 .
