He cons indifferent, and will not attack you, if you do not prompt him to :)
If you say "regret" or "Remorse", he answers, "That is not what I seek, but you will be happy to know that I have secured a place for you in the afterlife if you care to join me."
Saying "vengeance", prompts his quest text, as mentioned in the quest listed above.
-WARNING-
Hailing this mob will cause him to spawn 7-8 "Minions of Kotiz" (iksar skellie models), redcons to a 65. He also roots you with Vengeance of Kotiz. The minions themselves conned indifferent, until the root breaks (1min?). After that, they will proceed to pummel you (max hit 577 on 65 bard :P).
- edit -
Saying "Vengeance" will save you from his skellies, which will depop, if you say it before the root fades and they swarm you :)
