Help me build a Slayer of Domiel

[Heroditis]

I am thinking of bringing in a Slayer to our current campaign. The paramaters are as follows. Character level 9, moderate to low arcane magic available, standard character wealth, 36 point buy. I am thinking human, but am open to other races. The campaign is using the Greyhawk standard pantheon (as expanded by the LGG) with ongoing discussion about which Greyhawk dieties might sponsor a small order of Slayers. Any takers?

Thanks in advance,
Heroditis
