Character Overview

Master the art of speed-based combat with Calcium's unique mechanics

⚡ Passive Ability: Speed Demon

Calcium's speed-based power system works as follows:

  • Speed Buildup: Movement speed increases over time during combat
  • Damage Scaling: Higher speed = higher damage output
  • Damage Penalty: Speed resets when you take damage (except fall damage)
  • Fall Damage Safe: Taking fall damage does NOT reset speed
  • Risk/Reward: High damage potential but requires perfect damage avoidance

This makes Calcium a high-skill, high-reward character perfect for experienced players.

⚠️ Critical Warning: Damage = Speed Reset

Taking enemy damage resets your speed back to base - avoid it at all costs!

  • One hit resets all your accumulated speed
  • Important Exception: Fall damage does NOT reset speed
  • Perfect positioning and timing are essential
  • Consider health items only as emergency backup
  • Focus on mobility and avoidance over tanking

✅ Strengths

  • Infinite Speed Scaling: Speed builds up indefinitely
  • High Damage Potential: Speed converts to damage
  • Bone Weapon: Unique projectile with good range
  • Mobility Master: Outrun any enemy or projectile
  • Exciting Gameplay: Fast-paced, skill-based combat
  • Fall Damage Safe: Can use terrain without speed penalty

❌ Weaknesses

  • Damage Vulnerability: One hit resets all speed buildup
  • High Skill Floor: Requires excellent positioning
  • Unlock Requirements: Need to kill 1,000 skeletons first
  • Inconsistent Power: Performance varies based on damage taken
  • Stress Inducing: Constant pressure to avoid damage
  • Low Base Stats: No armor or shield protection

Unlock Strategy

Efficient methods to kill 1,000 skeletons for Calcium unlock

💀 Skeleton Farming Guide

Best methods to reach 1,000 skeleton kills:

  1. Use Sir Oofie: Tank character survives longer for more skeleton encounters
  2. Focus on Forest Runs: Higher skeleton spawn rate in forest areas
  3. Extended Runs: Aim for 15+ minute runs to encounter more skeletons
  4. AOE Weapons: Weapons that hit multiple enemies speed up the process
  5. Track Progress: Check unlocks menu to monitor skeleton kill count

Estimated time: 10-15 hours of gameplay depending on run length and efficiency
