Attack

Immediate Interrupt - Melee 0
Target: The creature climbing over the gate.
Attack: +7 vs. AC
Hit: 2d8 + 3 damage, and target is impaled, effectively grabbed by the gate (escape DC15). Grabbed creatures take ongoing 5 damage.
Miss: the character must make a DC15 Athletics or Acrobatics check to cling on, if they fail they fall off the gate- no damage.

Countermeasures

♦ An adjacent character can disable the spears with a DC 20 Thievery check.

♦ A character that makes a DC 20 Athletics check to vault over the gate is outside of the spike’s reach.
