Here are the RNG ability and ribbon chests.

I hate how this has really good abilities you can miss if you don't know that they only spawn in RNG chests, so here's what they are and where they are for anyone who cares:

WHITE MAGIC

Cleanse - Cerobi Steppe / The Terraced Bank, chest in middle on trap. 20% spawn chance/100% loot chance

TECHNICKS

Addle - Henne Mines / Special Charter Shaft, hidden path at south. 10%/100%

Shear - Barheim Passage / The Zeviah Span, south end, only accessible from West Annex. 10%/100%

RIBBONS

Abyssal / North section of Pharos / Subterra: This is part of the lower section that opens later (Black Orbs fun). Northwest section, west door, western path, 10% chance to spawn in corner.

Henne Mines / Special Charter Shaft: The reversed upper-case "L" section of this area, it's the upper-central part of this map (the "blob" at the lower left of the reversed "L" shape). 15% chance to spawn in corner.

You should make this as a guide so it doesn't just disappear into oblivion under all the crap posts in this forum.
