EXP Plus and other plus materia.

[XeQtR]

If i have the exp plus materia on one character, will all 3 party members gain the bonus, or do i need on for each?

And if i put two mastered exp plus on someone, will the effect be cumulative?

The last question goes for all the * plus materia. I've noticed that you can have two mastered hp plus, but a third one doesn't count, so is it the same with exp plus?

Only the character with the stat-boosting materia gets the benefit.
I'm pretty sure you can use as many HP/MP Plus materia as you like, and they'll all count, but not when your HP reaches 9999, or 999 for MP. The additional bonus will have no effect.

Not sure what happens if you use two EXP Plus...

I can't say for sure, but I think I tried with more than two hp plus at their initial level (10%), and only the first two helped. I also recall reading this somewhere.

As for the others, I guess there's no restriction, but i just want to make sure. Thanks for you reply ;)
