2493 was in my inventory, as well as 2 ratspider venom.
I had 6 aura at the time of the casting. 3 at the end of the turn.
( 6-5 for the spell + 2 )
17: Wait finished: today is day 17.
17: > use 908 2493
30: Consumed dead body [2493].
30: Don't have the required 782749 NPs.
I indeed didn't have gatecraft studyied when I ate him.
All other schools were known prior to the casting.
I had 3 NP available before and after the casting, so no I didn't lose any
NP,
in fact I still owe one for gatecraft (assuming I would get the spells of
course)
I will try again this turn.
Ruben.
