All the Dark Aeons CAN drop armours with 3-4 slots and any two abilities from: Ribbon, Break HP Limit and 1 more such as Ice Eater, Fire Eater, Lightning Eater, Auto-Haste, Auto-Protect, Curseproof, Auto-Regen, Deathproof and Auto-Phoenix. Surely that's in one of your guides? :P They also Drop Weapons with Break Damage Limit and other good abiities like 1-mp cost, first strike, alchemy, triple overdrive, triple AP etc. but most people will probably already have celestial weapons if they are fighting Dark Aeons so the weapons don't matter.

and if it costs 600,000 gil then how come when i ive them 500-540,000 gil i get 3 or 4 99% of the time? and also how come that the bribe FAQ also says "Monster: Marlboro
Bribe: Wings to Discovery x4 for 540,000 gil
Location: Calm Lands

Monster: Great Marlboro
Bribe: Wings to Discovery x8 for 1,280,000 gil
Location: Inside Sin, Omega Ruins"

so i was off with my great marlboro estimation but it's still more cost effective to bribe marlboros
