A way to bring back the shield bomb (or at least, the bomb) for Karma

After quite some thinking, I found a way to bring back her shield bomb.. well at least the bomb part of it.

This can be done by making her ally W (or self cast) an offensive aoe around the target rather than some buff.

Two examples I came up with are:

Deals damage in an aoe around the target Mantra W, increase damage a bit and some secondary effect (a debuff or slight CC)

Debuff or slightly CC in an aoe around the target Mantra W, increase debuff/cc and deal damage
