BC Cost Reduction

BC Cost Reduction (also known as 0 BC cost) is a passive effect that reduces the amount of BC required to use BB/SBB by a specific amount. This effect can be stacked with itself.

Examples of stacking

 * Gilded Seraph Vanila's 30% reduced BB gauge cost on her Leader Skill, Lunar Maiden QiuTong's 10% reduced BB gauge cost on her Extra Skill, Ragnarok Edict's 50% reduced BB gauge cost and Dragon's Amulet 10% reduced BB gauge cost equipped on a unit will give them 0 BC cost to using BB/SBB/UBB.

Tips

 * One viable squad building strategy in Colosseum is to create a 0 BC cost team by stacking this passive as high as possible. Example includes Gilded Seraph Vanila, Righteous Sun Cayena, and other units that provide a 30% reduced BB gauge cost as the leader and four copies of Lunar Maiden QiuTong, with all equipping spheres that reduce the unit's BC cost by at least 30%. Since this setup heavily relies on various sources of the buff, Leader Skill Lock, Extra Skill Lock, or Sphere Lock will ruin the setup.
