Prosperity Rune stack?

[Shujinko]

Since we can get more than 1 easily now with preorder bonus, I want to know if the effect will stack if we use more than 1?

Never tried before on the OG suikoden 1 since its hard to farm for it if you want more than 1.

i dont know but fortune rune is better go to that mining town alone from the begining of the game dont talk to ted, u go alone there talk to npc to get another fortune rune

you need to go southwest of your town then cross the mountain dungeon to arrive at that mining town

I know about the early secret to get one of the rune. I just want to know if having more than 1 prosperity rune effect will stack.

Fortune rune is not worth it to get since you can buy it later.
