Question about Vigor rune

If i attach a superior vigor rune and a major vigor rune on 2x different equipments will the effects of both runes apply ? or only one ? and can i use 2x of same rune to stack effect ? thanks

ony the superior ruune will count.

Nope, no rune effects stack.

2 minors give only 1.

2 majors only give 2.

2 major vigors only give 41.
