When planning, you can put two traps here, but you don’t have to choose the order of the traps. In the Trap Step, you can resolve the traps in either order.

Order is important not only because the first trap can eliminate an adventurer (and thus change which adventurer will be affected by the second trap) but also because the second trap is only affected by the anti-trap abilities that remain after the thieves and paladins deal with the first trap.

Example: Suppose we have a thief with 2 trap icons, the paladin with 3 trap icons, and two warriors in between. We played Rolling Stone (4 damage to the first adventurer) and Wall of Fire (1 damage to each adventurer, 1 extra to the last) in our Labyrinth. If we use the Rolling Stone first, then the four damage and also the first damage from the Wall of Fire gets prevented. The paladin will get no damage, the warriors will each get 1, and the thief (as the last line) will get 2 damage. On the other hand, if we use the Wall of Fire first, then its 5 damage gets prevented, and the Rolling Stone does 4 damage to the paladin. In both cases, five damage were prevented and four damage were dealt (but to completely different adventurers).
