Dreadful Invocation

Epic Tier
Prerequisite: 21st level, invoker, trained in Intimidate
Benefit: Whenever you score a critical hit with an invoker encounter or daily attack power, that enemy moves its speed away from you by the safest means available and takes a -2 penalty to attack rolls (save ends). Creatures immune to fear do not move and do not take this penalty.
