Grepha's GFB is
Counterspelled by the Xvart, causing the attack to fail. On the plus side, he blew a counterspell on a cantrip, and can't use its reaction again for the rest of the round.
The three guards move in and attack Leaf (hit once,
5), and Bokono (crit once,
16 and hit twice for
8 and
7) with their whips. They also attempt to pull Leaf prone, but he makes the DC14 Ath/Acr check. Bokono would have failed but he's immune to the prone condition. Two of them also use their bonus actions to attack with their shortswords, dealing
3 and
6 to Bokono, leaving it on 5/45HP if my maths is correct.
Senna, Sam, and Leaf are up. Senna starting her turn within Spirit Guardians provokes a DC13 wis save to halve [roll0] Radiant. Sam, Senna, and Leaf also need to make the DC14 Wis save or be Frightened of the Xvart, and therefore unable to move forwards.
