+# Multiplayer Boss Design Philosophy
+
+This project focuses on 4-player cooperative boss encounters.
+
+Bosses are not just enemies.
+Bosses are cooperative execution challenges.
+
+## Core Design Philosophy
+
+Boss encounters must test:
+- role execution
+- positioning
+- pattern recognition
+- sustained coordination
+
+Boss encounters should not primarily test:
+- raw stat checks
+- random power spikes
+- build luck
+
+## Role Model
+
+Roles are soft ratios.
+
+Players are not locked into hard classes.
+Each player contributes a mixture of:
+- Tank ratio
+- DPS ratio
+- Support ratio
+
+Bosses should require total role pressure fulfillment, not specific class presence.
+
+## Combat Identity
+
+Combat is:
+- non-target action
+- directional dodge-based
+- positioning-focused
+
+Survival should depend more on execution than on numerical advantage.
+
+## Signature Pattern Philosophy
+
+Each boss must contain at least one defining signature mechanic.
+That mechanic must:
+- create a clear player problem
+- have a clear expected solution
+- produce a clear failure result
+
+Ambiguous solutions are discouraged.
+
+## Revive Philosophy
+
+Revive is allowed, but revive must be risky.
+Bosses should react to revive attempts.
+Revive should increase encounter tension, not reduce it.
+
+## Sustain Philosophy
+
+There is no hard time limit by default.
+Instead, bosses should escalate over time.
+Encounters must become harder if players fail to execute properly.
+
+## Build Philosophy
+
+Build strength should support execution.
+It should not replace execution.
+Players should adapt builds, not brute-force encounters.
+
+## Encounter Identity
+
+Boss equals encounter.
+
+Bosses may include:
+- multiple entities
+- supporting units
+- positional hazards
+
+Adds must serve meaningful gameplay roles, never filler.
