I'm guessing he's a monk. Solo'd him as a 70 SK, and saw the message "Wei Zhang feels a healing touch" (mend?) twice during the fight, and it increased his hp by approximately 50%. He stuns a lot using the "Kirin Hoof" effect.
He dropped the following:
Drape of Transcendent Thought
MAGIC ITEM LORE ITEM
slot: BACK
AC:10
DEX:+6 STA:+6 CHA:+7 INT:+7 HP:35 MANA:40
SV DISEASE:+8 SV MAGIC:+7 SV POISON:+8
Recommended level of 58.
WT:0.4 Size:SMALL
Class: NEC WIZ MAG ENC
Race: ALL
Slot 1, type 7: EMPTY
and a silkworm.
