I cast cure on 1 target it heals for like 500-550ish (guess) or w/e I cast it on 4 it hits each for 200-250ish.
I know 500 isnt that acurate but I know for sure that I’ve never had a cure hit over 700 (250 x 4) = 1000. (heck even 200 x 4) = 800, so this is definately not the way it works.
I think it is more like:
1 target: 100%
2 target: 66%
3 target: 50%
4 target: 33%
