To reliably clear Apep Difficulty 16 on auto using an all-epic, budget squad in Dislyte, run Sander as your sole direct damage dealer while setting your four-star supports to target side minions. Apep triggers a lethal Toxic Detonation counterattack whenever he absorbs a set number of hits. Restricting boss attacks strictly to Sander limits the counter gauge while ensuring every hit inflicts heavy burst damage and suppresses boss Action Points (AP). Pairing Sander with a bulky, 100% Accuracy Djoser prevents Apep from healing, stabilizing the run without requiring legendary Espers.
How the Solo DPS Strategy Solves Boss Retaliation
Apep Difficulty 16 punishes multi-hitter compositions through its passive retaliation mechanic. When a team uses multiple attackers or wide area-of-effect skills, the boss counter gauge fills rapidly, resulting in frequent, back-to-back team-wide poison detonations that quickly overwhelm four-star healers.
Funneling all direct boss hits into Sander solves this bottleneck. Because Sander's abilities naturally scale with Speed and manipulate AP, his attacks delay Apep's turns while advancing the hit counter only when dealing high single-target damage. Keeping supporting units focused away from the boss ensures the counter gauge advances at a predictable, manageable pace.
Required Esper Builds and Targeting Behaviors
To execute this strategy, configure your team roles so that only Sander and Djoser interact directly with Apep, while your healers and buffers direct basic attacks toward the side Totems.
| Esper Role | Primary Objective | Gear Sets | Key Stat Priorities | Auto Target |
|---|---|---|---|---|
| Sander (Solo DPS) | Boss damage and AP reduction | Wind Walker, War, Fiery Incandescence, Apollo's Bow | SPD, C.DMG, ATK%, 80%–100% C.RATE | Apep |
| Djoser (Debuffer) | Maintain 100% Diseased uptime to block boss healing | Stonevein, Frost, Master Grove | 100% ACC, DEF%, HP% | Apep |
| Heng Yue (Cleanser) | Remove Poison stacks before boss detonation | Wind Walker, Panacea | SPD, HP%, Effect Resistance | Side Minions |
| Secondary Support | Provide shields, defense buffs, or extra healing | Astral Monitor, Master Grove | SPD, HP%, DEF% | Side Minions |
Gearing Priorities
- Sander: Prioritize Critical Damage on Uno II, Attack Percentage on Uno III, and Speed on Mui II. High Speed allows Sander to cycle turns rapidly and repeatedly push back Apep's AP bar.
- Djoser: Reach the 100% Accuracy cap before investing in defensive stats. Apep has high base Effect Resistance and recovers massive amounts of health if left unchecked. Djoser does not need damage stats; his sole function is surviving and reapplying Diseased whenever Apep cleanses.
- Sustain Supports: Equip cleansers like Heng Yue with high Speed and Effect Resistance. Cleansers must cycle their abilities frequently to purge Poison debuffs before Apep's attacks can detonate them.
Common Failure Points and Speed Tuning
While this solo carry framework provides high consistency for budget rosters, it intentionally sacrifices clear speed for safety. Runs will take more turns than high-end burst compositions, making execution precision critical.
Watch for these primary failure points when tuning your auto runs:
- Sub-100% Accuracy on Djoser: If Djoser fails to land Diseased due to insufficient Accuracy, Apep will heal through Sander's damage, dragging out the encounter until poison stacks wipe your squad.
- Support Stray Hits on Apep: If your supports are left on default auto targeting, their low-damage basic abilities will advance Apep's counter meter without dealing meaningful damage. Manually assign auto-battle priority for your utility units to the side minions.
- Cleanser Speed Misalignment: If your cleanser acts immediately before Apep rather than after him, Poison debuffs will linger on your squad through the boss's turn. Tune your support speeds so cleansers move shortly after Apep acts to strip venom stacks before the next hit triggers.
