Frozen Runes, How Often to Roll Damage?

[Bruno]

We have faced Evil Runes that affected/infected every hex in the hallway. DX rolls each turn with an additional -1 per hex you enter after the first, to find a safe place to put your feet. So if you move one step per turn, just a DX roll. If you move 5 hexes, you make one DX-5 roll or take damage once.

The wizard cast Levitate on everyone, which worked well until combat broke out in the hallway. Then we risked having people knocked down/out and onto the Evil Runes...

This variant is pretty entertaining, but I recommend only using it on a fairly modest stretch of hallway, particularly if your group don't have astronomical DX, good Climb scores, Jump skills, Levitate spells, or other ways to have a chance to get most/all of the party over.

Combat on/over/through Evil Runes is always extra-entertaining.
