Deltarune’s chapters feature clandestine adversaries far exceeding standard foes in power. These encounters demand exceptional skill, rewarding victors with unique items. Chapter 1’s elusive opponent, Jevil, presents a pivotal combat challenge for players.
Conquering Jevil’s Chaotic Challenge

Players face two strategic paths against this trickster: direct combat depletion or exhaustion through tactical maneuvers. The pacifist approach requires precise action sequences, while direct clashes demand perfect evasion skills. Combat phases escalate through five distinct stages:
- Stage 5: Randomized assault patterns from all prior phases
- Stage 4: Requires ≥6 fatigue points or ≤1400 HP
- Stage 3: Requires ≥4 fatigue points or ≤2100 HP
- Stage 2: Requires ≥2 fatigue points or ≤2800 HP
- Stage 1: Initial confrontation
Each transition introduces predetermined attack sequences before shifting to random patterns, culminating in Stage 5’s unpredictable onslaught.
Pacification Strategies
Inducing exhaustion (9+ fatigue points) enables non-violent resolution. Strategic use of Pirouette (20% TP cost) grants turn-specific benefits:
- Cycle 9: Full party healing (36-50 HP)
- Cycle 8: Jevil gains +25% attack potency
- Cycle 7: Randomized health bars (temporary)
- Cycle 6: Individual healing (25-55 HP)
- Cycle 5: Neutral effect
- Cycle 4: 30% attack reduction
- Cycle 3: Reduced invincibility duration
- Cycle 2: -4 defense modifier
Optimal rotation involves exploiting beneficial cycles while using Hypnosis (50% TP cost) to accelerate fatigue accumulation when sustainable. This method prioritizes endurance over aggression, testing players’ resource management skills.
