[My bad, been a couple of busy days. And given what Twinkle just rolled on her Con save, there will be little for her to do in the first round anyway, lol]

Con Save: 11

Twinkle almost gets bowled over by the mighty roar of the beast, only hearing a ringing echo that seemed to bounce around in her head endlessly. The monk is clearly shook and needs a moment to get her bearings back.

All she can do is move away from the owlbear. [Since incapacitated doesn't stop movement]

[Incapacitated for her turn, shaking the condition off at the end of turn.]

The owlbear therefore takes two attacks at Gimmond. An 18 and a 20 to hit (one hit, just) for 10 slashing damage.

Everyone is up. 

Zumfir will quickly rush towards Athos, healing him quickly (Due to Beacon, the healing is maximized)

Athos regains 24 health, and Zumfir retreats to not risk losing concentration.

Gimmond catches the first strike with his shield, but the second hits hard enough to leave him feeling as if the limb was nearly shorn off just from the force of the blow! He yet kept it together, planted his feet, and catches his third wind as he brought spear to bear once more into the flank of the owlbear with as much gusto as the beast had shown him!

Ba: Using Second Wind, regaining 13 Hp.
Mo: Into flanking position with Athos on opposite side of Owlbear.
Ac: Attack nearest small ooze with a most vicious spear!
Attack #1: One-Handed Vicious Spear vs Owlbear(AC ??) - To Hit: 19 For: 14 Piercing Damage. 
(Rolled a 2nd time with Savage Attacker for the 14 instead and also Sapping the target) 
Attack #2: One-Handed Vicious Spear vs  Owlbear(AC ??) - To Hit: 10 For: - Piercing Damage.
