I see stars.

Just gonna repost my comment because it has all the ideas. What do you guys think? Is there a better way on doing this?

"I like the ideas. Maybe not the Grimp Reaper aspect because it's done to death. You know what this makes me think about, though? The goofy hook that comes in to get bad acts off the stage in cartoons?

What if she had a switching spell that made her spells change from targeting allies to targeting enemies. Maybe toss passive CDR so it's not just a stance switch

Then you add something like "You're Up/You're Outta Here. She uses the hook to switch positions.

An ability like Encore/Boo! that reduces the CD of an allies most recent ability by 2sec and extends the CD of or disables the most recent enemy ability by 2sec (at max rank).

An ability called something like Break a Leg!, where she wacks an ally or an enemy with the cane. The ally gets an empowered auto and a MS boost, the enemy is slowed significantly

Or maybe an ability where she does the gate thing, but only skill shots and dashes go through it. You're Up and You're Outta Here has a reduced CD. for the duration. It can be centered around her and it could be lke "All the World's a Stage.""
