My crystal dragon had fading recollection cast upon it. He then equipped his deep elf fire dancer with sceptre of onus and used flameburst on the crystal dragon, knocking it over a chasm and killing it. It didn't even lose its ap before dying (had 3ap). If it helps, he was knocked back such that in the 2nd square of knockback he was over 1 chasm, and in the 3rd he was over 3 and died. Does this make any sense?
