and I'll likely change Seal Mind to be a mindpower-based offensive talent.
What about changing "Seal Mind" to something like "Share Pain" (working title) which can be cast on an enemy that has the Pain condition and that then gives that condition to all nearby enemies in a radius based on talent level?
It could have a fairly long cooldown (15ish?) and maybe also some passive effect. A possible one is to increase the range of Conduit of Woe.
Combined with a slight reduction in the cooldown of Harvest of Tears, and causing mind damage becomes suddenly much easier.
In addition, there is currently a significant functional overlap between "Mental Wound" and "Deadly Cadence". Both basically make a single enemy take extra damage over a very short amount of time. Maybe "Mental Wound" should be modified? I have a fondness for the Psyshot talent "Mind Worm" and would not mind to see it adapted to the Ruined class.
