If stage progression or timed boss fights are stalling your account in The Seven Deadly Sins: IDLE, prioritize summoning Bloody Ellie as your primary damage dealer and pair her with Merlin. Bloody Ellie supplies the raw damage output needed to overcome high-health targets, while Merlin provides skill support and debuffs to maintain team momentum.

Hero Roles and Gear Focus

To maximize performance, assign specific stat priorities to each hero based on their role within the squad:

MerlinUtility SupportCooldown ReductionReduce skill downtime to maintain debuffs and crowd control

How to Set Up the Duo for Stage Progression

  1. Focus Resources on Ellie First: Allocate your primary skill upgrade materials and highest offensive gear to Bloody Ellie. Her high base damage directly solves progression walls caused by strict time limits or enrage timers.
  2. Build Merlin for Skill Rotation: Equip Merlin with cooldown reduction equipment so her support skills cycle quickly. Her utility creates windows for Ellie to deliver uninterrupted damage hits.
  3. Align Skill Execution: Position Merlin so her utility triggers before or alongside Ellie's attack window. This prevents enemies from interrupting Ellie's high-damage strikes.
  4. Manual Skill Timing for Bosses: While automated mechanics clear general stages effectively, manual timing during difficult boss encounters allows you to sync Merlin's debuffs immediately before Ellie's primary skills hit.

Resource Allocation and Summoning Priorities

  • When to Pull: Pursue Bloody Ellie if your team lacks single-target lethal damage or struggles against timed stage limits.
  • When to Wait: If your frontline dies rapidly before DPS units can cycle their skills, allocate currency toward defensive support heroes before spending heavily on offensive banners.
  • Long-Term Progression Strategy: Treat Bloody Ellie and Merlin as your primary engine for stage pushing and resource farming. Use the increased material yields from higher stage rankings to build specialized units for future meta updates or specific elemental counter requirements.
