Charred Stone

Charred Stone is a natural floor tile encountered in Mindustry that inflicts the Charred status effect on units that stand on it. It appears as a scorched, volcanic ground type and functions as part of environmental hazards that interact with unit movement and survivability. Charred Stone commonly appears in maps or sectors with molten or burning terrain and is used to create dangerous zones that punish slow-moving or lightly armored units.

Standing on Charred Stone applies the Charred status, which scorches and slows affected units. The status deals 18 damage per second, reduces effective health by a 0.8x multiplier (incoming damage is increased accordingly), and reduces movement speed by 0.8x. Charred interacts with other natural effects: it has affinities that add 8 armor-piercing damage and extend the duration of Tarred when both effects are involved (Tarred duration can be extended up to 3.33s by certain sources). Some units are immune to specific terrain effects, but Charred does not list universal immunities in the available sources.

Gameplay implications and practical notes:

• Charred Stone is best avoided by fragile or slow units because it inflicts significant DOT and a simultaneous speed and health penalty. Fast, armored units can cross it more safely but still suffer the ongoing damage.
• Charred combines well with other environmental hazards or weapon effects that apply Tarred or Burning; the interactions can extend status durations and increase effective damage through armor-piercing affinities.
• Defensive base layouts should account for Charred tiles near approaches: placing walls or funnels so enemies must cross Charred can substantially weaken waves before they reach your defenses.
• Units or abilities that provide mobility, temporary invulnerability, or resistance to status effects mitigate Charred’s impact. Conversely, weapon systems that ignite or scorch can create Charred-like zones to control enemy movement.
• The health multiplier shown by Charred does not change a unit’s numeric health stat; it alters how much damage the unit effectively takes (damage is divided by the multiplier after armor is considered), so the apparent “reduction” behaves like increased incoming damage rather than a lowered max HP.
