Manaless

Manaless Champions are Champions in the League of Legends, which do not possess any Mana. While the largest number of Champions use Mana, some Champions actually use their Health as Ability Cost. A minor number of Champions however use no Cost at all. They are fully played on Cooldown.

Cooldown Champions
Cooldown Champions, like Katarina, use no kind of Cast Cost. Their main advantage is their steady fight ability, without requiring any regeneration like Manaregeneration. Their main disadvantage, however is their lack of stunning or crippling abilities (e.x. Slows). The only Cooldown Champions right now are Garen and Katarina.

List:

 * Garen
 * Katarina

Health Champions
Health Champions use their own health to cast their abilities. Their main advantage is their possible focusing on their Health Regeneration, as they don't have to waste time for regenerating Mana or Energy. Their can literally fight to death. Examples for Health Champions are Mordekaiser and Tryndamere. Tryndamere can defy death for some time even if he uses abilities by using his Ultimate.

List:

 * Dr Mundo
 * Tryndamere
 * Mordekaiser

Energy Champions
Energy Champions use a special kind of Attribute to use Abilities. They have a Energy Bar, which has 200 points. It's main advantage is it's fast regeneration (50 Energy per 5 seconds). There are currently no Energyregeneration increasing items, which can be seen as a hard disadvantage. The Ancient Golem buff however increases the Energyregeneration by the same percentage as Mana. The neutral point of Energy Champions are the frequency of their abilities; they do possess short Cooldown, yet their Energy is quickly drained. Energy was recently added.
