But...

Lol. My healing is higher than yours now and I haven't casted one spell or trained any combats with anyone, nor have I been hunting.

You never mentioned the word "gain." You simply pointed out that it was amusing to you that your skill in healing was higher than mine without you casting any spells (which is actually irrelevant) or going hunting.

Without knowing the number of heal attempts you went through, and then what skill level you started and ended at for the sample, we can derive nothing about your actual gains. But, we apparently never will since you seem reluctant to actually provide any useful information in this thread to go with the rest.
