Here's one to get it started.
Fossil strike cost 2 AP
Bloated corpse cost 1AP
Flaming Crescendo cost 2AP
Flaming crescendo deals its damage after 3 turns OR when the target dies. So you can simply fossil strike, summon a bloated corpse and cast flaming crescendo on it, then detonate it for a triple combo effect. /w adrenaline or lone wolf you can take it even further into:
Poison sting 2AP
Fossil strike 2AP
Bloated corpse 1AP
Flaming Crescendo 2AP
I'm not sure if supercharging the bloated corpse increases the crescendo damage or the explosion damage! Yet to be tested.
What spell combos have you come up with thus far?
