Hi! This bug was reported to me by Gi Nattak: it is possible to cast Roulette via the Rage and Sketch commands (e.g. Veteran), but casting it this way means that only the enemies are valid targets, and instead of giving you the finger it just picks a target. This patch puts Roulette, as cast via Sketch or Rage, more in line with the actual spell by making it mimic the enemy version of the spell, which adds a rotating finger as part of the casting animation (in contrast with the Lore, which has it as part of the selection of the spell itself).
A few things to note: I wasn't entirely sure at first that this really qualified as a bug, but what had me convinced was that only enemies are valid targets. Also, I was careful to ensure that there was no loss of compatibility with Mimic.
