The Battle Effects, often referred to as Buffs and Debuffs, are a battle mechanic in Xenoblade Chronicles X. During battles, several strengthening and weakening effects can occur that can change a character's stats, abilities, and behavior, and their activations depend on the Arts used, the surrounding Battle Probes installed, and the ongoing Weather effect.
Buff[]
Melee Accuracy Up: The Melee Accuracy stat increases.
Ranged Accuracy Up: The Ranged Accuracy stat increases.
Ranged Power Up: The damage of Ranged Attacks increases.
Beam Res Up: The damage taken from beam attribute attacks decreases.- Barrier: A certain amount of damage is reduced from all attacks taken by the user.
- Supercharge: The damage of the next art is doubled; the buff wears out afterwards.
- Decoy: A certain number of enemy attacks are avoided, ignoring Accuracy and Evasion.
Weather and Battle Probe Induced Buffs[]
- All Attribute Resist Up: Damage from all attributes is reduced, decreasing total damage taken.
- Critical Chance Up: The critical rate increases.
- Ether Attack Up: The damage of Ether attribute attacks dealt by the user increases.
- Debuff Res Down: The enemy's existing Debuff resistances decrease, making it easier to inflict those Debuffs.
- Skell Fuel Recovery: Skell Fuel steadily increases; does not affect parked Skells.
Mobility Debuffs[]
- Stagger: The character is knocked back, preventing them from attacking for a brief time. The Stagger status will persist even once a character can move again; during this time, topple arts have a higher rate of success, and a Skell Bind will be possible.
- Knockback: The ally is pushed backwards, further than they would be with Stagger.
- Stun: The character faints.
- Sleep: The ally falls asleep and remains inactive, but will be awakened if hit by an attack.
Status Debuffs[]
- Blackout: Reduces Accuracy and Evasion. Ranged attacks will also do less damage.
- Blaze: Thermal damage is inflicted at regular time intervals.
Weather Induced Debuffs[]
- Ranged Accuracy Down: The Accuracy of Ranged attacks decreases.
- Melee Power Down: The damage inflicted by Melee attacks decreases.
- Weather Damage: Heat: Thermal damage is received at regular time intervals.
- Weather Damage: Lightning: Electric damage is received at regular time intervals.
