Rings M-Attack value?

Newyn - Heavens Tear

Was playing with my gear and noticed that I only got 20 magic attack when equping my Magic Rings(48). (288 before equping 308 when equiped)
Sence they have 35 magick attack in the base I wonder if it should be like this or is somthing wrong?

Were you already wearing a ring that you equipped over, or had you taken the other rings off before comparing?

I removed my rings before.

The ring's magic attack value isn't a literal constant that's added to your base magic attack. It counts as part of the gear damage (same as your weapon). Generally I've always got more base magic attack than the ring says though.

as other person said above

there's like a formula somewhere along the line of

mag (atribute)xmag attack (gear)=mag attack output


but believe me the magical attack on your weapon or on your rings has a big difference on your output

if u put on a ring with +20mag attack will be about 100 more dmg depends on the magic u have
