So I thought of a way to make The Acolyte better. Without reworking her completely. However, I still would think of reworking her completely and take away the healer tag and make her an attacker, or support.
I also made a change to keep her more inline with top end characters.
Strike from the Shadows - Deal Physical damage to target enemy (change, with a 40% chance to gain Stealth for 2 turns.) If stealthed deal double damage.
(If from shadows it should be like a backstabbing)
Sacrificial Magicks - Deal Special damage to target enemy. (Change if a finishing blow and gain to) If stealthed drain 25% Turn Meter and remove all negative status effects from allies.
(To capitalize oh her stealth instead of taking away from Asajj getting a killing blow)
Thrill of Victory- Nightsister Acolyte has +10% Critical Chance and (change and recovers 20% of her Max Health when scoring a Critical Hit.) and gains Stealth for 2 turns whenever an ally or enemy is defeated.
(Having her gain stealth in this fashion feels more like a passive then having to use a turn to maybe gain stealth)
