Transformation effect

Transformation Effect is name of effect of certain skills and items in TERA that turn your character different.

Typical example is berserker's Unleash, which transforms the character and replaces all skills with new ones. The effect is not apparent with some skills. Ie. mystic's Apex buff toggle Thrall Augmentation is counted as Transformation Effect. This skill earlier had green aura that was later removed (since you should use it always anyway). It is noticeable since you cannot enter the Dressing Room while under Transformation Effect (error message "Dressing Room is not available during transformation").
