Not sure that I like this, but we'll see what happens as all of it is subject to change. However, I'd prefer to just cast and remove the duration, or keep it duration based and remove Venari's health. If not, Venari dies, Venari dies. Recast for energy - maybe with a small cooldown; similar to what happens in Onslaught. Otherwise, I'm happy with these planned changes so far! I already love Khora as she is, so this is all great to see.
*Even after clarifying that Venari will likely be able to be revived, I still don't like the idea of having Venari basically just be another kavat in the revive department.
