It is neither of those, however, I did intend on Indy Ploys being a part of his character since Aleph only thinks ahead in very rare cases, as you might have noticed. Otherwise, he wouldn't be in this fight XD

Aleph reserves this particular technique for foes who prove to be very difficult for him to deal with. You can say it is a Trump card of sorts, and its use means he acknowledges the strength of whom he fights. But I can almost guarantee that because of it, Aleph will be leaving the fight as the one who ends it, against the strongest rock thrower or not. 

Another hint: His second blessing is usually important in using it.
