Spark Boost

Spark Boost is an effect that boosts Spark damage. If multiple Spark Boosts effects are used, they will stack additively, regardless if the boosts are buffs and passives. It is one of three multiplicative damage bonuses, with the other two being Elemental Damage Boost and Critical Damage Boost.
Unlike other damage bonus buffs, Spark Boost buffs can activate and update in the middle of unit attack animations.
Unlike Critical Damage Boost effects which have a hard cap of 700%, Spark bonuses do not have a cap.
For more information on sparking, see Spark.
Certain Spark Boost effects can also boost BC, HC, and Item drop rate upon sparking, including items such as the following. Much like Spark Boost and Drop Rate effects, BC/HC Drop Rate on Spark effects occur on a per hit basis, stacking additively to their respective bonuses.

==Examples of Stacking==
===Spark Damage===
*Hallowed Dance Sefia’s 130% Spark buff on her BB/SBB with Wisdom Flower (150% Spark) equipped will result in a total 280% Spark bonus.
*Hallowed Dance Sefia’s 130% Spark buff on her BB/SBB and Holy Emperor Karna Masta’s 180% Spark buff on his BB/SBB will not stack with each other. Whichever unit reaches to the enemy target last will have their Spark buff active.
===BC/HC/Item Drop Rate===
*A unit equipped with Quintan Emerald will have a total BC drop rate of 85% (35% as base BC drop rate + 50% from Quintan Emerald) and a total HC drop rate (10% as base HC drop rate + 50% from Quintan Emerald) of 60% only on hits that spark. Otherwise, non-sparking hits will have a BC drop rate of 35% and an HC drop rate of 10%.
