Each time you use a spell, gain 1 Dark Point. The effect of this ability changes on the amount of Dark Points you have.
1 Dark Point: Deal 144 (+8 per level) ranged damage to all nearby enemies.
2 Dark Points: Summon three Black Whelps.
3 Dark Points: Teleport behind an enemy, instantly dealing 409 (+10 per level) damage.
4 Dark Points: Deal 20% of an enemies health as damage.
5+ Dark Points: Deal 100 (+5 per level) ranged damage to an enemy for each Dark Point you have.
*Specify your hero's statistics (especially range). If you don't know, how much your hero should have, you may use scaling from 1 to 10 or describe in words (low, high, massive, poor, mediocre).
*Add talents. Talents are part of a hero and they describe them more than abilities, in example the thing that Tyrande has healing doesn't make her support at all if she'll take all damage perks.
*Clarify the way how Dark Points works (I mean, when do you lose them, what's the limit etc). Right now, it looks like each time you use a spell, you get a Dark Point. Dark Points stack infinitely and are never lost. This means, that you have only one opportunity to cast the first four variatione (as they grant a Dark Point) and after the first 10 minutes, you can probably kill each enemy hero with one click.
*Add cooldowns and mana costs to your abilities. They are as important as the skill's effects.
