Ok, couple of things with regard to the rules. Legend is what powers your special abilities. You can take a number of epic abilities up to one less than your legend. With legend 2, you can only have Epic <whatever> at level 1. Personally I think Legend 3 is a better choice than 2, but thats just me for you. Plus each point of Epic <whatever> gives you 1 automatic success in that ability, which is quite useful at times. 2 dots of epic, 2 successes.
Relics can do a few things. Weapons, armour, transport, stat boosting stuff are their innate powers. They also give access to the purviews (Sky, Justice, War, and so on), which allows the Scion to channel the boons of those purviews. Optionally a relic can be something simple, say a ring, that only grants access to a purview.
The more it does, the more dots it costs. Good rule of thumb, one dot per special. Weapon with stat boost (accuracy and damage), and access to the purview of justice .. 2 special things, 2 dots.
Bastet is part of the Egyptian pantheon. Coming from the deep south, one of the Loa (Voodoo) might be more suitable, but I can't remember if they have a trickster .. they probably do. There is a fan made pantheon for the native american gods, I found it last week. It looked ok.
I think you'd enjoy things like the purview of chaos and illusion (illusion is in the Ragnarok book, not the core).
