I figured folks here would get a kick out of this... Was running with a small PG team a week or two ago and they tried to make a pentagram around A points using Warlocks. This is about as close as they got before combat forced them to disperse. I'm kind of glad, who knows what they would have summoned should the pentagram been formed.
Looks like ancient Chinese Kung fu The Kung fu grand masters would heal each other and share Kung fu knowledge
Seer Council is actually a totally valid tactic on some maps. Maybe 4 Warlocks and 1 Dire Avenger to cap.
