How to play and combo preview

Written guide · based on the official ability texts

Renata Glasc is a control support: her attacks mark enemies, and her allies deal bonus damage to marked enemies. Handshake roots and throws, Bailout delays an ally's death, Loyalty Program protects and slows, and Hostile Takeover drives the enemies it hits into a frenzy.

Renata Glasc's strengths

Her attacks mark enemies and her allies deal bonus damage to them.
Bailout delays an ally's death and lets them survive if they take part in a takedown.
Hostile Takeover turns the enemies against each other.

Renata Glasc's weaknesses

Depends on the presence of allies to benefit from her marks.
Handshake has a long cooldown (16 s) and is cast blind.
Bailout has a 24 to 28 s cooldown: choose the ally well.

Role in team fights

Renata controls the engage: she roots an enemy or sends them toward her allies, protects her carry with Bailout and Loyalty Program, then triggers Hostile Takeover when the enemies are grouped. Her marks raise her allies' damage on the target.

The pick

When: An enemy is isolated.

Handshake roots the first enemy hit; recast it to throw them in a direction; Loyalty Program slows and protects.

Protection

When: An ally is about to die.

Bailout delays the ally's death and lets them survive if they take part in a champion takedown.
