Whenever a Dark Side ally loses Advantage without scoring a critical hit, they gain Advantage for 1 turn at the end of the turn.

Whenever a Dark Side ally gains Advantage, if they didn’t already have it, they gain a bonus based on their role:

• Tanks Taunt for 2 turns
• Attackers gain Critical Damage Up for 2 turns
• Supports and Healers gain 20% Turn Meter

Unique 1: PRESS THE ADVANTAGE
FINAL TEXT: (ZETA) Supreme Leader Kylo Ren is immune to Stagger and can’t gain taunt effects, and enemies defeated during his turn can’t be revived.

Whenever a Dark Side ally loses Turn Meter, they gain 10% of their current Max Health and Max Protection (stacking).

Whenever a Dark Side ally gains bonus Turn Meter, they lose 10% of their current Max Health and Max Protection (stacking).

Unique 2: GALACTIC LEGEND

FINAL TEXT: (ULTIMATE) Supreme Leader Kylo Ren dispels all debuffs on himself, enters an aggressive stance, and deals Physical damage to all enemies, which can’t be evaded. While in this stance, Kylo is immune to damage and detrimental effects, he can’t be defeated, his Siphon is doubled, and his abilities have no cooldowns.

• 85% Ultimate Charge: Aggressive stance lasts for 2 turns
• 100% Ultimate Charge: Aggressive stance lasts for 3 turns

Supreme Leader Kylo Ren can’t use this ability if he is already in an aggressive stance

 

 

Now a bit of the Developer Insight into the new Kylo Ren:

The Basics:

• Supreme Leader Kylo Ren is one of the first two Galactic Legends to be released along with Rey.
• Supreme Leader Kylo Ren is primarily focused on dealing damage and increasing his strength over the course of an encounter, but he doesn’t care about keeping his squadmates alive throughout the battle.
• His stats grow over time through a new effect called Siphon and can be very strong in longer encounters.
• Supreme Leader Kylo Ren’s Galactic Ascension event, Heir to the Dark Side, takes you through Kylo’s story in The Rise of Skywalker up to the battle atop the wreckage of the Death Star. At this point in the story (and the part of Kylo’s journey that this unit represents), Kylo is still held by the Dark Side and is consumed by his goal of crowning himself the ruler of the galaxy.
