Corp:
Spirit Shield (Unblessed!)
Holy Elixir (Or whatever the hell it is that blesses it. This is so that spirit shields are actually rare-ish, instead of everybody and their mother having 4.)
Divine, Ely, Arc & Spec Sigils
Godsword Blades
Godsword Shards 1, 2, & 3.
(Not hilts?)

Jungle Demon: The barrows 1
Barrows.

Barrelchest Monster
Anchor, like its supposed to.

Strikewyrms (Ice, Jungle, Desert)
Make Slayer Helms a lower drop rate, add other things like frost dragon bones, Tome of frost from ice strikewyrms?

Penance Queen:
Something good, and the blue infinity top.

Nomad:
Dragon Platelegs (rare) & Dragon Platebody (?) (rarer)

These are all things that would be on top of what they already drop, so it would (except for the rarity changes) be only adding to the drop tables.
