Kushnak ferociously flies at the illithid. As soon as he is within range, however, the illithid's staff glows again and dark energy shoots into Kushnak's body. The half-orc suddenly feels almost crippled, at least compared with the strength he usually enjoys.
Kushnak tries to hack into the creature, but, in his weakened state, he feels his blow repelled by an invisible shield around the creature.
Erdolliel, using her invisibility to the best advantage, strikes at the creature's head. This time, the creature is right where she thought it was, and blood begins to flow.
The illithid retreats closer to the ground. Kushnak and Erdolliel both try to find openings, and this time the elf slashes the same wound she just opened.
Fury in its eyes, the creature sends forth a pulse of mental energy that threatens to simply shut down the duo's minds.
Both Kushnak and Erdolliel fight through it, ready to engage the creature again. While Erdolliel fights through it, Kushnak's psyche can't handle the stress. The half-orc mind suddenly stops cold.

[sblock=OOC]Kushnak: charges
Illithid: ready triggers; casts empowered ray of enfeeblement at K, touch attack 13+ hit, 11 STR penalty
Kushnak: continues charging; attacks 1, 7+ (I think that would be +9 now, right?) miss
Erdolliel: moves down to 35 feet above floor; attacks 1, 15+, miss chance 81, hit, 23 damage
Illithid: moves down 20 feet
Kushnak: AoO, 5+ miss
Erdolliel: AoO 20!, 15+, miss chance 59, crit, 32 damage
Illithid: mind blast K and E; saves, E: 18+ success; K: 6+
(thank goodness for bonus from Prot Evil) success fail, K is stunned
Two things. I already asked o3 to check on anything pertinent we need to figure out (other than his attack bonus and damage bonus) that is affected by his STR loss. Also, I don't see anything in the mind blast saying that it is mind-affecting (so as to be warded from by mind blank).
