Reduce All

Reduce All is a in Xenoblade Chronicles 3. It decreases the affected character's, accuracy, evasion, and defense.

Reduce All gives the target -30% damage, -30%, -30% to Evasion group 1, and -50%. (This cannot be increased, as there is no effect which increases the power of debuffs inflicted by an Ouroboros.) It lasts for 60 seconds at base. Uniquely among party-inflicted debuffs, it entirely bypasses debuff resistance, although it won't be applied if the inflicting art misses the target.

Reduce All is, without doubt, a very strong debuff to inflict on enemies. Most enemies do not have huge amounts of additive damage, so the 30% loss results in a big cut to their damage output, especially when combined with the missed attacks due to the loss in accuracy. The penalty to evasion can be useful against enemies that have high dodge chances, but the real offensive strength lies in the negative damage reduction; there is no other way to inflict negative damage reduction on enemies and very few have nonzero damage reduction under ordinary circumstances, so Reduce All effectively provides a x1.5 damage multiplier on all attacks that hit the target.

While its duration can't be increased by regular effects, it is still naturally high at 60 seconds. Taion's Unceasing Curse skill can reduce the rate at which the debuff ticks on enemies, effectively making it last longer or, if the skill is at max level, indefinitely until the Ouroboros form is canceled. Generally though, re-applying the debuff shouldn't be hard if the player manages Interlink level or the Unlimited Sword timer correctly.
