Donating perks or buffs

[TioBF]

I've seen a couple of times in the game they ask for donation, may i ask if it grants you something better in the future?
Like the guy on the boat or at the chocobo part.

Found it myself for anyone who want to know
the old'Gil or however its called, the amount you donate its a discount fo a future mission and on the Operation for fighting sin they give loot but people say they are not worth it

do you mean o'aka?

All his items are expensive. Until you donated 10000+, 10k is very easy to farm.You only have 4 chances to donate to him. His stock changes everytime you see him. He does have some great equipments for your party. He sells 4 empty slotted armors for your whole party at end game. Which is extremely good if you plan to fight dark aeons etc. The best armors you have to craft yourself and 4 empty slotted armors are needed for you to fill in what you want.

0 - 100 gil → all items/weapons will get 100% increase in prices.
101 - 1000 gil → all items/weapons will get 50% increase in prices.
1001 - 10000 → all items/weapons will get 20% increase in prices.

10001+ → items/weapons will get 30% discount on all prices.

However,

@ Mihen Operation - the guy that ask you for donation will give you something based on how much you donate. TBH, the stuff he is giving out are trash so you can ignore it.
