Item Rating(potential) and Enhancement(star) System

Maybe an useless question but.

Are the self skills canceled by the usual ones ?

Example : i cast self SE then usual sharp eyes from an archer.
Am i getting both ?
Or (that's more what i think. But . . .) both works and add their own effects ?

Thanks for the answer.

Great guide too.

(Even if i don't really like the 'Question / Answer' Thing since it means the guide itself is not complete. But DW, great guide ^^)


Editing because i have another question : (not idiot that one ).

If the item already have a % stats (thanks to a 'nice' identifying), if i use an enhancement scroll, will these be able to go higher ?

thanks again.

Mini-buffs and normal buffs don't stack.

As far as I know, nothing can affect the potential bonuses, chaos included.
