Wall of Fire takes the rim warps (rules rev 39)

A warp mouth at the maze's edge is a corridor — the wraparound connects
it to the opposite rim — so the fire may bar it. It takes BOTH mouths
(each with its own burn-out clock), and the crossing steps through flame
for the usual 4 from either side. Older ledgers refused the cast and
replay so.
