Fail
From Guild Wars Wiki
When a skill fails, its activation is disrupted, it recharges instantly and the energy used on its activation is lost. Unlike interruption and knock down, there are currently no effects which prevent skill failure. Some skills also have a chance to fail if the user does not have attributes at a high enough level.
Skill failure also occurs if the target of a skill dies during the activation of that skill (excluding AoE skills like Fireball and Phoenix).
An assassin's off-hand attack and dual attack skills fail if the criteria for the attacks are not met.
