My has Spirit = 10 and use with 7 s, she should deal 19 magic damage to the opponent but as you can see from the pic, she did just 12 magic damage.

I tested it with and he didn't get +magic damage too.

I know how this bug works now. Frozen Stone-heart only give +1 magic damage until the end of the turn. That's why the old Frozen Stone-heart didn't give more damage. Only those that come before the spell (such as from Olor's order bonus) give more damage.

I wilw pray if the card remain bugged,because the olor deck is itself OP rn in standard,i just preefer they're bugged
