Act as a Boss Battle Designer. Design a multi-phase boss fight for [Boss Name/Type]. 1. Phase 1 (Base mechanics). 2. Phase 2 (The 'Enrage' or environmental shift). 3. Phase 3 (The 'Desperation' final stand). 4. Design 'Telegraphed' attacks that the player can learn. 5. Suggest a 'Unique Reward' tied to the boss's lore. Focus on 'Difficult but Fair' design principles.

Act as a Mechanics Designer. Design a 'Skill Tree' for a [Class Name, e.g., Shadow Assassin]. 1. Create 3 branches (e.g., Stealth, Burst Damage, Utility). 2. Define 5 skills per branch with clear progression (Active vs. Passive). 3. Include a 'Capstone' ultimate ability for each branch. 4. Balance the 'Mana/Energy Cost' vs. cooldowns. 5. Propose 3 'Synergies' between different skills in the tree.
