As Sarith falls, the shield guardian releases its stored spell and necromantic energy washes over the beholder. It is caught off guard by this and seems to take the full effect.
The construct then turns to the beholder and smashes it in the side of its large body once, but misses with its follow-up attack.
Melpomene's conjured hand squeezed the beholder, wounding it slightly, but not seeming to worry it much.
Mai'ngor's rage is overwhelming as he sees two of his longtime companions dead in front of him. He ignores the ogre attacking him and charges the beholder, unleashing all of his rage and grief on the creature. It's clearly never seen a mere warrior so boldly attack it and tries to float away as the tikbalang attacks. He can't get out in time and dies within seconds, blood everywhere.
Once the beholder is down, it takes but a moment to finish off the ogre.
