The 3rd trait for the Stormcaster hero gives a lightstorm at the start of every turn.
I’m using a Stryx team with a stormcaster hero and Phoenicia. Phoenicia needs a firestorm to be worthwhile. The Stormcaster is using the Phoenix crossbow to set off a firestorm. If I had the 3rd trait enabled… Phoenicia would never be able to get the double damage bonus off firestorm.
So a toggle button to disable a trait would be handy thing.
