Agreed with the fact that this necro wasn't really needed, but since it's revived now might as well talk about it.
I'm curious to see how well this does in the current environment. One major flaw I see is the single burning tower - if you can't get out that destroyer you're screwed. Cremation seems much better.
Tempted to test a variant with that change as well as aether and grav pends, time towers, and earth mark, with maybe the time and earth reversed.
