Effects of the joining on magic

Gaining magic

 * In some occasions, the taint strengthen the newly joined warden's connection to The Fade. It can help a late onset of magic beyond the standards of the race (Only by few years, no more than a decade older than onset age).
 * The person must have showed signs of some connection to the Fade at young age but it wasn't enough for manifesting magic on its own
 * It's a very rare occurrence, talk with a staffer if you want apply that to your character ICly or in its history.

Losing magic

 * Mysteriously, the taint at older age can work quite the total opposite of the previous effect As it can make a newly joined Warden lose the ability to enter the fade consciously and bring their magical abilities to an end.
 * It can't happen at young age, only possible if the joining is made at +25 years old.
 * Usually it happen only to mages who has haven't developed their magic thus far, stopped at the basics and learned to control it and maybe with just few spells. Well trained mages can't lose their magic by the taint.
 * It's a very rare occurrence, talk with a staffer if you want apply that to your character ICly or in its history.

Faster magic development

 * It's known that Wardens gain a boost in their abilities from the joining, while warriors gain more strength and endurance, rogues more agility, mages can start to master their spells faster than any non Warden mage. Some scholars believe that comes from the faster aging rate the taint provide.
 * This faster development of magic compensate the shorter lifespan of the Wardens. So a forty year old mage Warden can have pool of spells not possible for a non Warden before hitting fifty.

Developing new spells

 * The taint in its casual form gotten from the joining can't develop any special spells. But with Avernus research, he could prepare Alchemical Concoction the Warden can drink to gain these spells.

Known spells

 *  Mage : Dark Sustenance, Bloody Grasp
 * Rogue : Dark Passage, The Tainted Blade
 * Warrior : Blood Thirst, Blood Fury
 * General : The Warden gain an ability to track and hunt darkspawn disciples [Must be developed from the Warden own blood and it accelerate the rate of taint corruption]

Interaction with other alien blood (Reavers)

 * Some warriors has other alien blood in their veins already, like reavers who drank dragon blood ritually to gain special blood spells/talents. There have been no observation of any unusual changes among reavers who join the Wardens (apart from more discipline they get from training)
 * The only significant interaction happens when reaver use the spilled darkspawn blood to heal himself and take it into his veins (Using Devour), as it increase the healing effects and accelerate the taint in the reaver blood. Excessive using it will cause the remaining years for the reaver before hearing the calling to diminish.

Taint and Blood Magic

 * The blood mage Warden can tap into the darkspawn and manipulate them, control them and enhance the Warden ability to sense other darkspawns accurately, whereas a non Warden mage cannot do that.
 * The more a blood mage Warden does do that, they accelerate the rate of taint corruption in themselves, essentially speeding up their Calling, so it is not recommended.
