Greek Fire Trap or Weapon Revised
(+ 2 to defuse if trap if the player knows or can define historical "greek fire" to the GM's satisfaction)
When a trap or weapon spurts its ancient napalm fire at you, ROLL+DEX.
On a 10+, you find suitable cover.
On a 7-9, you dodged but choose 1 anyway:
Your weapon melts on your hand.
Your armor burns and leaves you breathless for a while.
Say goodbye to your backpack.
On a 6-, you must choose one and take 2d6 damage from the flames.
