Orb guardian corpse effects
Orb guardians should give more interesting effects when eaten.
Currently, practically all orb guardian corpses give bad (if any) effects, so practically the only use for them is to trade them for potions. In order to make it more appealing to eat them instead, I suggest the following guaranteed effects given by the corpses. Naturally it should be balanced by more corruption (~4-5 effects or so).
Snake From Beyond - water breathing intrinsic
Ancient Chaos Wyrm - fire immunity and 1000 castings of Fire bolt or Fireball.
Yulgash - teleportitis and teleport control (thought being the other RFE where Yulgash should be able to teleport despite the level restriction, also since teleportitis without control IMO ruins the fun in any possible game.
Ancient Stone Beast - the elementalist class power 50 of burrowing through stone.
Nuurag-Vaarn is rather balanced already.
