During the 2nd Anniversary event in The Seven Deadly Sins: IDLE, spend your saved Diamonds on the Choice Heroes Banner to pull targeted units that fill specific role gaps in your main team composition. Using the Choice system guarantees that currency spent goes toward preferred heroes, making it significantly more effective for reaching key star levels and hero potential milestones than pulling on standard banners.
How the Choice Heroes Banner Works
The Choice Heroes Banner allows players to select specific target heroes from an available event pool before spending Diamonds.
- Targeted Odds: Selecting a hero concentrates your pull odds on that character, reducing reliance on general pool RNG.
- Progress Acceleration: Concentrating pulls on a designated hero lets you acquire duplicate shards faster, which is required to raise star ratings and unlock higher hero potential levels.
- Roster Alignment: Direct targeting ensures spent Diamonds contribute to your existing team goals rather than fragmenting resources across unused units.
Prioritizing Heroes Based on Team Gaps
Before spending Diamonds on the Choice Heroes Banner, identify your team's immediate bottleneck in campaign or combat stages.
| Roster Problem | Primary Banner Target | Desired Stat/Function |
|---|---|---|
| Frontline dies too quickly | Tank / Defensive Support | High durability, shields, or taunt skills |
| Timer runs out on boss stages | Single-Target or AoE DPS | Raw damage output, critical hits |
| Team damage lacks scale | Buffer / Utility Support | Attack speed boosts, critical damage amplification |
Always prioritize heroes that provide functional value across both PvE progression and competitive game modes over single-purpose niche options.
Diamond Allocation and Trade-Offs
While high-volume Diamond summons (such as spending 100,000+ Diamonds) yield significant duplicate shards, evaluate your account's stopping point to avoid resource depletion.
- Check Milestone Thresholds: Spend Diamonds until you hit a major star upgrade or potential unlock on your target hero.
- Avoid Diminishing Returns: If a unit is already at a high star level and near maximum capability, incremental stat gains offer lower progression value than holding Diamonds for future unit releases.
- Maintain a Safety Reserve: Avoid emptying your entire Diamond balance down to zero. Retaining a reserve ensures you have currency available for upcoming limited banners or essential support releases later in the season.
