So spirit pain is triggering riposte on yourself and I assume other effects related to on hit/dodge

Code:

Spirit Pain! Jace Winters begins to attack The Common Scholar, but is possessed by a spirit and attacks themself!
Jace Winters takes 27 Darkness damage.
Jace Winters attacks Jace Winters with Comet and misses them!
Jace Winters attacks Jace Winters with Ashura and misses them!

He riposte'd his own riposte.
Although this leads to some humorous things, I'd imagine this wasn't intentional.

In addition. It seems another hexer can override the others' spirit pain. The one used last will take affect over the first.

These aren't bugs, except maybe the Riposte shouldn't trigger if you're attacking yourself. So I'll change that.

Related: A Spirit Pained Electrojam also triggers "Wired" (It's electric counter.)

Intended?

Basically it's triggering "When hit/attacked" effects.
