I can be leveled up and it works properly.
so if Level 1 has 30% damage reduction and Level 2 has 50% reduction, Level 2 work? I mean some maps got this problem that some item-based abilities don't work on Level 2
you can level up any ability via learning by heroes by setting Data(Or Stat?) - Hero Ability to True. i think the same goes with Spell Damage Reduction (i know some abilities have problems with learning via hero, if i'm not wrong some are Item Life Bonus, Item Mana Bonus)
Yes. Being able to level it up and it then working correctly means just that
Just asking, How could I do an ability useless without a specific unit. Passive Ability to be exact
I don't understand what you're asking here. Could you rephrase the question?
