Calcium Complete Guide
High-risk, High-reward Character That Relies On Maintaining Speed.
This build weaponizes Calcium's speed to deal more damage, making him a fast and agile character. His passive ability grants him speed over time, but it is halved when he takes damage, making him a high-risk, high-reward character. The core strategy is to prioritize speed items to maximize damage while avoiding all incoming attacks. While his performance is highly dependent on his ability to avoid damage, a successful run results in an unstoppable character that can kite enemies and deal massive damage.
- Primary Mechanic: Calcium gains damage the faster he moves. His speed periodically builds up over time when he does not take damage.
- Scaling Strategy: The build scales by stacking speed and projectile damage to maximize damage output.
- Core Playstyle: A fast-paced, skill-based playstyle that focuses on mobility and perfect damage avoidance.
- Power Curve: The build starts off strong and is great for map traversal, but its power is inconsistent and depends on avoiding damage.
