During the 1.5 Anniversary update for The Seven Deadly Sins: IDLE, claim your 300,000 free diamonds immediately and pull on the featured event banner to unlock and awaken Traitor Meliodas. Channeling this currency windfall into duplicate pulls and potential stat upgrades provides the fastest increase to your team's combat power.

How to Spend the 300,000 Free Diamonds

The 300,000 free diamonds supplied in the 1.5 Anniversary celebration shift resource planning from conservative saving to aggressive investment. Instead of holding currency, spend these diamonds on event-exclusive opportunities that yield immediate power spikes.

Use your currency according to the following priorities:

  1. Traitor Meliodas Event Banner: Spend diamonds until you hit banner pity thresholds to guarantee multiple copies of Traitor Meliodas. Duplicate pulls are required for awakening tiers that deliver major base stat increases.
  2. Hero Shards: Allocate surplus event currency toward hero shards if banner pulls fall short of your next awakening rank requirement.
  3. Potential Stat Enhancement: Invest remaining diamonds into the potential stat system to keep your combat power aligned with higher stage requirements.

Avoid spending this diamond windfall on standard summoning pools. Event banners offer targeted value that resolves combat power bottlenecks faster than standard pools.

Building Around Traitor Meliodas

Traitor Meliodas serves as a primary frontline or mid-line DPS unit designed for sustained damage in long encounters, including the Tower of Trials and boss raids. Because his performance scales heavily with offensive stats, team composition should focus on amplifying his damage while maintaining frontline stability.

  • Support Synergy: Pair Traitor Meliodas with support units that grant Attack or Critical Rate buffs to maximize his total output.
  • Defensive Balance: Do not spend every diamond exclusively on offensive growth if your supports are dying early. Keep healing and defensive units leveled so Meliodas can survive multi-wave fights.
  • Versatility: Meliodas fits into most general compositions without requiring niche setups, making him an easy drop-in upgrade for underperforming damage slots.

Equipment and Progression Management

Rapidly increasing hero levels through diamond spending pushes your overall team combat power higher, which triggers harder stage scaling. To keep pace with rising stage difficulty, match your hero awakening levels with corresponding gear investments:

  • Equipment Sets: Upgrade active hero equipment alongside hero rank-ups to prevent sudden durability drops in later waves.
  • Artifact Shards: Farm daily event missions to accumulate high-tier artifact shards and refined upgrade stones that are difficult to obtain outside anniversary events.
  • Daily Event Checklists: Complete event-exclusive daily tasks to earn extra materials needed to maintain stable automated stage clears.
