User blog:Crimson Storm Mich/Guide: Omni Evolutions: Cross Spark and Resonance

Overview
One hidden feature about the Omni Evolutions is their Resonance ability. Resonance is activated by Cross Sparking two or more Omni Evolutions. Sparking an Omni Evolution unit with non-OE units will not make Cross Spark trigger so be advised.

Cross Spark
Cross Spark is triggered only when the damage distribution of 2 or more OE units reach 150% have been sparked For those who don't know, damage distribution is how your damage is distributed between each hit. (durr) For example, OE Eze has a hit count of 2 and while you might think his distribution is 50, 50, nope. Eze's real distribution is 10, 90.

Note: Damage distribution is most commonly capped at 100%, no more, no less.

Provided below is the damage distribution of each starter. For easier understanding, the numbers are the % of each hit in order.

Resonance
Once you meet the requirements for Resonance, your party will get some extra buffs that will stack with regular buffs. Resonance will only last for 2 turns where the counter will reset and you need to spark 150% damage distribution again.

Resonance provides the following buffs:
 * 10% Atk/Def/Rec per unit that's the same element of the OE unit after the first one
 * E.g. Selena + 3 water units = 30% Atk/Def/Rec
 * This stat bonus can be used in stat conversions
 * Only applies to units of the same element as the OE unit
 * 5% OD fill rate per unit that's the same element of the OE unit after the first one
 * Applies to all allies
 * 1% elemental damage reduction to the element the OE unit is strong against per unit that's the same element of the OE unit after the first one
 * Applies to all allies
 * E.g. Mono thunder team = 5% Water mitigation
