Sphinx Claws are just a temporary solution. I get pounce Next level, at Weretouched Master (Tiger) 3. Then, they get switched with a new bind, and I'll get Rageclaws back.
I was actually looking at Totem Avatar. Having a Grey Render show up ontop of his armour would be awesome, and gives me 7 HP and a potential 5 armour.
However, I need to find out what slots my shapes take up. Dragon Tail is either feet or waist, and Blink Shirt is heart. Totem Avatar, thus, can fit on the arms, feet, or shoulders, for some HP and Natural Armour, (I'm not going to be investing much essentia into natural weapons, but Blink Shirt... )
(Also, Next level, I'm binding Totem Avatar to my shoulders. +1 Damage Die Size, or a max total of like 6d6 for some attacks.) But there are better options.
For this level, I can shape Kruthik Claws to my shoulders, and get a +4 to Hide and MS. +2 for each Essentia, so slightly better than Worg Pelt.
Lammasu Mantle might be good. +2 Deflection against Evil (With +1 for Essentia)
Alternately, Wormtail Belt for +2 Natural Armour, with the same essentia deal as above.
If I end up using my Safewing Emblem, I'll probably go for Peg. Wings, If I can slide them into a non-shoulder slot.
So, I think I'll go with WT Belt, and see how it continues.
