Yeh I'm still new to 4e so I wasn't sure about healing surge stuff :)
Presume I spent 2 of my healing surges beforehand, pumping my hp back up to 24/26.
Rah using move and attack parts of Open The Gates of Battle.
Move Phase:
OPTGoB: "move +2"; "you don't provoke opportunity attacks from the first enemy you move away from".
moving F11 -> F9 -> C6 -> C5 -> E3 (8 squares)
After move, using Hunter's Quarry on the E2 goblin.
Attack Phase:
Dexterity vs Reflex
attack roll: 15
http://invisiblecastle.com/roller/view/2584556/attack = 1d20 + 4 = 15 + 4 = 19 vs Reflex
If hits, using stone flurry for 3 + strmod = 3 + 2 = 5 damage
damage roll: 11
http://invisiblecastle.com/roller/view/2584569/quarry roll: 3
http://invisiblecastle.com/roller/view/2584572/damage = 3d10 + dexmod + quarry + flurry = 11 + 4 + 3 + 5 = 23
