Encounter Design

Combat in Nephibis is an action RPG system — deterministic formulas, stat scaling, crit builds, dodge mechanics, and percentage-based damage reduction. There are no levels: every number on both sides comes straight from stats. When designing encounters, read the party's sheet first and build from what you see.

Scaling Philosophy — Read Stats, Not Levels

Enemies scale to the party's stats. Before placing anything, read: max HP and pools (Stamina/Energy/Mana), the top damage stat (STR for melee, DEX for ranged, INT/WIS for powers), Speed, and Perception. Match or pressure those numbers — never a level, because there isn't one.

Enemy Type	Scaling	Purpose
Most enemies	Party-scaled stats	Consistent challenge
Fodder/mobs	Static (low)	Power fantasy — let players feel strong
Minibosses	Fixed/narrative	Gatekeepers and story beats
Bosses	Fixed + archetype scaling (below)	Climactic, high-stakes encounters

Party-scaled guideline: build the enemy's key stats near the party average, then shift by intent — easy: clearly below party's best numbers, normal: even, hard: above in one stat, deadly: above in two with a seam (a counter, a cooldown, an escape).

Area Difficulty Zones — Stats, Not Levels

Zones describe the stats that live there. A street human with modest stats loses in a military compound; an Omega walks through slum thugs without noticing. telegraph with fiction (armor, auras, wreckage), not numbers.

Zone	Who lives there	Example Areas
Safe	Baseline humans, low stats	Residential areas, markets
Normal	Trained humans, modest gear	Commercial districts, suburbs
Dangerous	Veterans, splices, light chrome	Bad neighborhoods, gang territory
Extreme	Mutants, nanos, heavy chrome	War zones, demon territories
Death	High-tier powers, war machines	Active battlefields, dimensional rifts
Apocalypse	Omega-tier and up	Omega-tier threats, cosmic entities

Creature Tiers — Threat Bands

Creatures carry a threat band, not a level:

Band	Role
Street	Mobs, pests, basic threats
Elite	Soldiers, wildlife, combat drones
Monstrous	Special forces, alpha predators
Calamity	Mutant beasts, elite demons, named bosses
Cosmic	Omega mutants, demon lords, space entities, reality warpers

Boss Scaling by Archetype

Every Boss file carries bossArchetype + scalingNotes. Read the party, then scale what matters for that archetype — direct fights care about boss stats most, indirect fights care about the situation most:

• Direct (duelist, brute, warden). The boss IS the fight. Boss stats matter most: set its damage near the party's per-exchange output and its HP/speed so standing trades are a genuine contest. The Warden is the template — match or slightly exceed the party's damage, force choices about trading vs mobility.
• Swarm Commander (hive lord, summoner, captain). Minions carry the fight; boss stats matter moderately. Keep the boss itself near party average and put the pressure in numbers, positioning, and reinforcement tempo. Set the dossier's compensatesWith to Minions plus one more (Environment, Time Pressure).
• Mastermind (scientist, trapper, puppeteer). Machines, traps, and counters carry the fight; boss stats matter least. The boss body can be frankly weak — even baseline-human stats — while its systems hit like a boss. Set compensatesWith to Puzzles/Traps/Counters and write scalingNotes around what the machines read (party Perception, INT-systems play, pool drain) rather than the boss's STR.

Whichever archetype: a boss weaker than the party still feels like a boss by leaning on its archetype's carriers — puzzles, traps, minions, environment, stakes (hostages, timers), counters. A weak Mastermind with a hostage in a trapped lab is scarier than a strong Direct boss in an empty room.

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.

Bosses: No Caps, Many Approaches

Use the Boss file type for bosses (or Creature for beast-type bosses). Bosses carry no cap — a boss's stats are whatever fits that specific boss. A cosmic-tier boss can exist if the story needs one.

Every boss is beatable three ways (see the Boss System GM instruction): learn its mechanics (the intended path), prepare (intel, prep, environment — worth ~2 difficulty steps), or overpower it (raw per-exchange damage above its Overpower Threshold — breaking mechanics always costs something, usually an enrage). The Boss System catalog covers the common defeat conditions: core-exposed, regen-lock, element-locked, adds, power-drain, counter-adapt, speed-gate, shield-gate, arena-lock, phase-wall — each with a tell, a counter, and a break threshold set from party damage stats.

High-Stats 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 stat-200 fighter clearing 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 Power Blocking

NPCs don't outscale the party's demonstrated tier until the party demonstrates it. If the party's best stats sit at street level, the world's heavy hitters stay rumors, distant auras, and one-sided warnings — not stat blocks. When the party breaks into a new tier through play or breakthrough, matching opposition unlocks.

Exception — bosses: Bosses are exempt. Their stats are set by the specific boss's design, not by the party, so a boss can be far above you (a terrifying gatekeeper) or far below you (a miniboss that must be solved, not fought).
