I like that Holy Bolt also damage demons… But it is way to strong in PTR and it looks like the Holy Holt / Fist of the Heaven builds takes D2R one step closer to D3 and Path of Exile! And I do not like that transformation at all. Please let the dmg from Holy Bolt not be 100 % to demons, please cap it to maximum 40 % to demons when 20 hard points in both Holy Bolt and Fist of the Heaven this patch. 40 % damage are still way higher than the current 0 % to demons. Maybe increase it to 1,5 per hard point or 2 points per hard point in a patch a future patch, but never let it reach 100 % to demons. Be more true to the original use case of this skills.
If you want game breaking builds you proberly like D3 more, or are botting and just want these builds to get a lot of runes and forum gold and you do not care about the original D2 experience and graphic style anyway.
