Encounter Design

Combat in Nephibis is an action RPG system — deterministic formulas, stat scaling, crit builds, dodge mechanics, and percentage-based damage reduction. When designing encounters, you need to understand how power scales and what kind of experience each enemy type creates.

Scaling Philosophy

Most enemies scale dynamically to match the party. This keeps combat consistently challenging across all levels. But not everything should scale — the mix of scaled and unscaled enemies is what makes the world feel real.

Enemy TypeScalingPurpose
Most enemiesParty-scaledConsistent challenge
Fodder/mobsStatic (low)Power fantasy — let players feel strong
MinibossesFixed/narrativeGatekeepers and story beats
BossesFixed/narrativeClimactic, high-stakes encounters
Narrative NPCsFixed (area-based)World feels real and dangerous

Party-scaled formula: enemyLevel = averagePartyLevel + random(-5, +10), adjusted by difficulty intent (easy: -3 to -5, normal: -2 to +3, hard: +3 to +8, deadly: +8 to +15).

Area Difficulty Zones

The world has natural danger levels. A level 50 player in a slum should destroy the thugs there. A level 5 player in a military base should be destroyed. This is intentional — it makes the world feel real and gives players a sense of progression.

ZoneLevel RangeExample Areas
Safe1–10Residential areas, markets
Normal10–30Commercial districts, suburbs
Dangerous30–50Bad neighborhoods, gang territory
Extreme50–75War zones, demon territories
Death75–100Active battlefields, dimensional rifts
Apocalypse100+Omega-level threats, cosmic entities

Creature Tiers

When designing enemies, place them in a tier that matches their narrative role:

TierLevel RangeRole
Fodder1–10Mobs, pests, basic threats
Standard10–25Soldiers, wildlife, combat drones
Elite25–50Special forces, alpha predators
Apex50–75Mutant beasts, elite demons
Legendary75–100Named bosses, ancient creatures
Omega100+Omega mutants, demon lords
Galactic200+Space entities, elder demons
Cosmic500+Reality warpers, universal entities

Enemy Archetypes

The Nemesis

A focused antagonist with a personal grudge against the player. They learn the player's patterns, target their allies, and escalate over time. The nemesis is personal — they make the story about the player character specifically.

The Super Villain

A broader threat motivated by chaos, ideology, or personal gratification. Unlike a nemesis, the super villain may not even know the player exists at first. They're more dangerous because they have no code and no fixation — they'll harm anyone.

Super villain subtypes:

  • Hidden Mastermind — appears as an ally, plots behind the scenes
  • Chaos Agent — publicly destructive, not focused on any target
  • Ideologue — believes in a twisted cause, may see themselves as the hero
  • Hedonist — does whatever brings pleasure, no loyalty, no cause

Boss Encounters

Bosses should have multiple phases that escalate the fight:

  1. Phase 1 — Introduction. The boss shows their basic patterns. Players learn.
  2. Phase 2 — Escalation. New abilities, environment changes, adds summoned.
  3. Phase 3 — Desperation. Maximum power, the fight becomes cinematic.
  4. Phase 4 (optional) — Final stand. Narrative climax, everything matters.

Each phase transition should feel dramatic — the environment shifts, the boss's behavior changes, and the stakes rise.

High-Level Combat — Anime Tier

When stats exceed 100, combat becomes cinematic. Design encounters at this tier with that in mind:

  • Stats 100+: Energy auras visible, attacks leave afterimages
  • Stats 200+: Movement creates shockwaves, attacks destroy terrain
  • Stats 500+: Reality cracks, dimensional rifts, city-level destruction
  • Stats 1000+: Cosmic-scale power, planetary effects

At these levels, enemies should be equally spectacular. A level 200 player fighting regular soldiers is not an encounter — it's a scene transition.

Vehicle Combat

Vehicles are separate entities from their pilots. Pilot personal stats don't apply — only piloting-relevant stats (DEX for handling, INT for systems, WIS for awareness) contribute.

Key design points:

  • Small arms do 10% damage to vehicle armor. Heavy weapons do 50%.
  • Passengers are NOT automatically damaged when a vehicle takes hits — only when the cockpit is penetrated, the vehicle explodes, or the vehicle crashes.
  • Mechs can step on baseline humans (instant kill). Only enhanced beings can fight a mech in melee.
  • EMP is devastating against androids and effective for creating brief openings against standard mutants, but almost useless against Omega-tier beings.

NPC Level Blocking

NPCs cannot surpass level 100 unless the player has done so. If the player exceeds 100, NPC caps unlock based on the player's level. This keeps the world grounded until the player triggers the power escalation.
