Eruption counter

Eruption counters are a type of counter introduced in Doctor Who. They act as a counter for damage dealt to creatures and players when chaos ensues.
==Description==
Eruption counters first appeared on <c>Pompeii</c> in Doctor Who. They act as markers on the plane card with one being added whenever a blank is rolled on the planar die. Then whenever chaos ensues damage is dealt to each creature and player corresponding to the number of the eruption counters. This represents the pressure building up until the volcano explodes.
