The potions of body restores are an interesting addition. I always look at them as "the noob resource until the restore spell" or the potion-er money maker at Mira and I kind of disregarded them in favor of the strong restores. However for small mirrors or no fail-safe restores can be helpful.
A warning: BRs CAN'T REPLACE RESTORES! I really doubt that such thing is ever possible in the swamp.
