        if target:HasModifier("modifier_suns_embrace_ally") then
            dmg = dmg * (1-MR)
        end

If magic resist is negative (via Rule Breaker or Tamamo W), then damage is increased instead.

        if target:HasModifier("modifier_suns_embrace_enemy") then
            dmg = dmg + dmg*MR
        end

Similarly, if magic resist is negative (with Tamamo W) then damage is decreased.
