Talk:Spike Flail

I'm confused about this particular mob weapon skill. I thought it was supposed to hit everyone in range with hate. A mage in my alliance cured a PLD from a rival linkshell who had just claimed Fafnir. Hate was transferred and Fafnir used Spike Flail killing almost my entire alliance, but the original claimers were untouched by it and continued to kill Fafnir. I'd like some clarification on what Spike Flail can and cannot do.

Also, how does 1339 HP - 1019 HP = instant death?
