Paladin stats & race

[Snaggles]

With enough dex a Dawnfire is going to do 10-20dps average from the proc alone (1-2ppm x 585).

You could also go with a Poison Wind Censer gnome build and the cultural arms. With SCHW and those you can self-haste to 60%. Wear a fungi and just club away. Gale of Poison is nasty to get hit with but you have heals for days.

I'd say "it's going to slow down in the 50's" but soloing a pally to 60 isn't exactly a thrill so any sadist who can do that could probably be fine with a cleric...
