Making him somewhat stronger than regular mages/spiders so he can survive some punishment but still won't be tough enough to make a proper thug. You could give him reasonable (But not very high) point cost and high path costs, but give him multiple paths. AWSN sounds like a good selection to me, since he's the bringer of rain (AW), maker of stars (S) and teacher of agriculture (N). Maybe AAWSN to stress the tricky nature of air magic. These would also be nice paths for Machaka since many aren't readily available to national mages.

Also, I wouldn't recommend naming the avatar "Anansi" - call it "Divine Spider" or something. This way Anansi would be the natural name choice, whereas "Spiderman the Anansi" sounds pretty lame.
