Hero Level refers to the experience level of the player character in Remixed Dungeon. The hero level affects various game mechanics, character capabilities, and progression.

Experience is gained primarily from defeating enemies. The amount of experience required to reach the next level depends on the game difficulty:

• Normal/High Difficulty (difficulty > 0): 5 + (current level × 5) experience per level
• Easy Difficulty (difficulty = 0): 5 + (current level × 4) experience per level

This means on normal difficulty:

• Level 1 → 2: 10 EXP
• Level 2 → 3: 15 EXP
• Level 3 → 4: 20 EXP
• Level 10 → 11: 55 EXP
• Level 20 → 21: 105 EXP

On easy difficulty, requirements are slightly lower (4 EXP per level instead of 5).

Upon leveling up, the hero gains:

• +5 maximum HP (ht increases by 5)
• Immediate heal of 5 HP
• Increased awareness (chance to detect hidden traps/doors) up to level 10
• +1 skill point (every level if max skill points > 0)
• Skill point accumulation (max skill points / 3 added to current skill points)

• Gnoll: Gains a skill level every 5 levels (levels 5, 10, 15, etc.)
• Warlock: On level-up, heals min(max HP - current HP, 1 + (depth - 1) / 5) and satisfies 10 hunger
• Lich: If at max skill points when dying, can resurrect once (consumes all skill points)

• HP: Base HP increases by 5 per level (modified by class starting HP)
• Awareness: Increases with level up to level 10, formula: `1 - (0.85 for Rogue / 0.90 for others)^<sup>1)</sup> * 0.5)`
• Spell scaling: Some spells scale with caster's skill level (which is separate from hero level but related)
• Kunai Throw: Damage scales with caster level
• Enemy scaling: Some enemy stats scale relative to dungeon depth/hero level
• Death statistics: Hero level is recorded in death events for analytics

• Skill Points (SP): Used for learning skills/talents, max SP increases by 1 per level (if > 0)
• Magic Level (skillLevel): Separate from hero level; increases via specific items (Tome of Mastery, etc.) or class mechanics
• SP accumulation: On level-up, current SP increases by maxSP / 3 (rounded down)

• EXP formula verified: `expToLevel()` returns 5 + lvl() * 5 (difficulty > 0) or 5 + lvl() * 4 (difficulty = 0)
• Level-up benefits verified: +5 max HP, heal 5, awareness update, skill points
• Class specifics verified: Gnoll skill level every 5 levels, Warlock heal/hunger, Lich resurrection
• Awareness formula: `1 - (class_factor)^<sup>2)</sup> * 0.5)` where class_factor = 0.85 for Rogue, 0.90 for others
