TFT Update: Soulbound Class
Senna and Lucian enter Teamfight Tactics together, bound beyond life and death. As Soulbound, these two damage dealing carries fight past their own mortal limits as long as the other is still alive.
Here's how they work:
Soulbound
(2) The first Soulbound unit to die in a round will instead enter the Spirit Realm, becoming untargetable and continuing to fight as long as another Soulbound unit is alive.
Senna
Cost: 2
Origin: Shadow
Class: Soulbound
Ability: Piercing Darkness
- Senna fires a beam through her furthest ally, dealing 50/100/150 magic damage to enemies, and buffing allies' on-hits for 5 seconds to deal 25/45/65 magic damage from Senna.
Senna is a back-line unit that focuses on buffing allies as well as dealing damage. Her ability Piercing Darkness infuses any friendly in the beam with bonus on-hit magic damage applied from Senna, allowing her Shadow trait to benefit from many more takedowns in a combat.
Lucian
Cost: 4
Origin: Light
Class: Soulbound
Ability: The Culling
- Lucian fires at 4 times his normal Attacks Per Second in a direction for 4 seconds, each attacking for 20/30/50% of his AD, applying on-hits, and dealing 30/40/50 magic damage.
Lucian is the new carry for the Light trait and is especially adept at single-target DPS. His ability Culling synergizes very well with damage modifiers like Piercing Darkness and applies on-hit effects.
Oh, and we almost forgot about Amumu
Cost: 5
Origin: Inferno
Class: Warden
Ability: Curse of the Sad Mummy
- Amumu’s rage explodes, dealing 250/500/1337 magic damage to enemies within 2/3/4 Hexes, and stunning them for 1.5 seconds.
Inferno at the 6-piece level has been a bit underwhelming. Specifically, it lacks the utility to compete with other all-in compositions (Light, for example). Enter Amumu - he’s here to be the tanky frontline for all of your Infernal needs. He roots enemies in Inferno Hexes and is generally an adorably cute, but often lonely, force of raw destruction.
