The collaboration between Mobile Legends: Bang Bang and Attack on Titan is officially back. The game features updated skins, events with free rewards, calendar bonuses, an exchange shop, and a draw system. 

1. Event Duration and Structure

According to in-game data, the collaboration lasts for 30 days, and activities are divided into two phases:

• Phase 1: December 12–16
• Phase 2: December 19–23

Most updates and reward availability are tied to server time at 5:00 PM (CET).

2. Updated MLBB × Attack on Titan Skins

Promotional screens indicate that all three collaboration skins have received enhancements:

• Martis — "Levi" Skill Visual Effect Optimization — updated skill visual effects.
• Yin — "Eren" Transformation Effect Optimization — improved titan form animation and visualization.
• Fanny — "Mikasa" Skill Visual Effect Optimization — reworked movement and attack effects.

Skins are available through the Draw Event and Event Shop.

• 1x Draw — 25 diamonds (50% discount)
