Move: Walk from P12 to M12
Standard: Provoke Overextension vs BT1
Attack: (1d20+15)[18](33) vs AC
Hit: (2d8+9)[6][5](20) damage and BT must make a basic attack against you as a free action. If the basic attack misses, an ally (Sathris) of yours can make a basic attack against the target as a free action.
Bravura Presence: Kriv gains a bonus to AC against the BT1's basic attack equal to your Charisma modifier (5) and Sathris gains the same bonus (5) to his basic attack's damage roll.
TLDR: Kriv moves in and attacks BT1. If he hits, then BT1 has to make an attack against Kriv, who has a +5 bonus to AC against that attack. If BT1's attack misses, then Sathris gets a basic attack with a +5 bonus to damage.
