Echadar Dumril, Eladrin Warlord

Echadar recoils when the guard swings at him, channeling his outrage into a low slash, creating another opening for the Dragonborn to strike.

Immediate Interrupt upon being hit (before the damage/prone applies): Vengeance Is Mine: Bel'Shazar and I both MBA vs him, while still flanking.
My MBA: (1d20+12)[16] vs AC, [roll]1d8+5[/rol] damage.
Bel'Shazar's MBA: (1d20+10)[25] vs AC, (1d12+4)[16] + (1d8)[7] damage.

actual turn depends on the outcome of this, because if that killed him, I'm not prone :)
