Adrenaline

Certain Warrior skills are fueled by adrenaline rather than energy. It is gradually built up each time the Warrior hits or is struck in combat, each such blow being added to the characters adrenaline level. Some skills increase the rate of adrenaline build up, while others expend it entirely.

Adrenaline Points
Adrenaline is not actually gained in strikes, but in points. Every adrenaline skill stores its own adrenaline points displayed by rising flames from 0 until fully charged. See this table for approximate number of adrenaline points needed for skills.

1 4 "strikes" on Cleave do not equal 4 "strikes" on Sever Artery. The "Points needed" column increases linearly; the "adrenaline strikes needed" in the skill descriptions are a simplification. A "strike" of adrenaline in the skill description equals 20-25 points. A real "strike" of adrenaline gives 25 points.

Gaining adrenaline
Gaining adrenaline means every adrenaline skill in your bar gains that many points. For every attack you make that hits, you gain 25 adrenaline points. For every 1% health lost from your maximum, you gain 1 point of adrenaline. For every 25% of your health lost, you gain approximately 1 "strike" of adrenaline--the equivalent of an attack landing. Note that health lost includes ranged attacks but excludes health degeneration. Commonly, 4 strike skills are charged in about 3 hits time, because you take some damage at the same time, assuming that the opponent is attacking you.


 * Soothing Images sets all adrenaline gain to 0. You can still use adrenaline attacks under Soothing Images if they are charged; the skill just prevents you gaining any more adrenaline until it ends.

Using adrenaline
You can only use adrenaline skills that are fully charged with adrenaline. They cost 0 Energy. When you use an adrenaline skill, all adrenaline skills in your bar lose 25 points. These lost 25 points can be recovered with your next hit (including the adrenaline attack itself), or by taking as much damage as 25% of your maximum health.

Losing adrenaline
Losing adrenaline means every adrenaline skill in your bar loses its full load of adrenaline. You lose all adrenaline after you do not take any damage and do not attack for 20 seconds, or when you die.


 * Some warrior skills cause "...lose all adrenaline." These skills are: Hammer Bash, Heavy Blow, Wild Blow, Final Thrust, "On Your Knees!" and Shove.
 * Sympathetic Visage and Ancestor's Visage causes a loss of all adrenaline when an adjacent foet enchanted with it is struck.
 * Blackout also causes a loss of all adrenaline in addition to disabling all skills.
 * Wail of Doom is similar to Blackout but disables only attack skills.

It is believed that Ferocious Strike and Balts Spirit both only give 1 strike of adren gain, no matter what your skill may be.
