question about runes

I have a max armour sunspear 5 set I put a death minor on one peice and a blood minor on the other

the question is what do I do with the other 3 peices.. well I used other runes and I want to know for example if I have 2 runes on 2 different peices of armor will they stack their ability or will it be the same effect like when I put two minor runes on two different armors (same minor runes) it still only upped my death magic by one even though I had two runes I know it doesnt work for attribute runes but does it work for the rest of the runes



if I put this on four armor peices will those spells now be cast almost instantly
or will it just be 25%

just 25%. that's what "Non-stacking" means, that it doesn't add up. compare Rune of minor Vigor to Rune of Vitae

Effects from runes only apply once per attribute. You won't get +2 from 2 minor runes; you'll only get +1. If you have a Superior Death and a Minor Death, you only get +3, not +4. Anything that says "Non-stacking" will not stack with another piece. You won't get +250 health for 5 Superior Vigors, just +50. You won't cast the spells instantly with 4 Bloodstained inscriptions, just 25% faster.

Note that with major and superior runes, the -35 or -75 health DO stack. So be careful with that unless you want to intentionally lower your max health (there can be certain advantages to that which i won't explain). Also the +1attribute from your headgear stacks with runes which means you can max an attribute to 16 (12+3+1).
