Bringing this up again... v0.30 patch c.
I hope there are plans to work on Barbatos. With 3 turn, 3 move summons, it's too frequent that one player or another starts within striking range of him: especially on a small map! And starting within range of Barbatos = death, no way around it. That's not fun.
Also, the lich has some buggy AI behaviour. I just played a (short) game where his summons could reach me in one turn but he didn't immediately wipe me out. Wraiths and elementals only started being summoned once I built a worker and moved it one tile closer to Barbatos. If I moved the worker out of this range, Barbatos stopped casting. Any existing summons would erratically attack my capital, stay still or go wandering.
The second weird behaviour is that for a while, Barbatos was casting every turn but no summons were appearing. Was he casting some sort of spell on himself? It happened for at least 10 turns in a row, then he went back to summons.
Lastly, Barbatos did finally assault my capital without being enticed by a worker. But it took over 150 turns for him to do it
