Charred

Charred gives your cat Bruise 1, meaning it takes 1 extra damage from every hit, but makes the cat completely immune to Burn. Burn immunity means fire attacks, lava terrain, burn-inflicting abilities, and any source of the Burn status effect have no impact on your cat. The Bruise 1 penalty is minor compared to the full Burn immunity, making this a net positive disorder in most situations.

Charred is heritable and can pass from parent to kitten through breeding. It can also be acquired through events or applied with a Disorder Syringe from the Organ Grinder. The Burn immunity is particularly valuable because Burn is one of the most common and dangerous status effects in Mewgenics, appearing on many enemy attacks, terrain tiles, and environmental hazards. Being immune to it removes a significant threat vector.

Charred is the perfect pairing for Spontaneous Combustion (15% chance to Burn 5 self and adjacents when hit) and Flaming Fists (Burn 1 on basics, start with Burn 1), as it negates the self-inflicted Burn from both disorders while keeping their offensive effects. With Charred, Spontaneous Combustion becomes a pure offensive tool, and Flaming Fists loses its self-damage downside entirely. Even without fire synergies, Charred provides solid value in fire-heavy environments. The +1 Bruise is negligible compared to the immunity benefit.
