the CHANCE portion stack multiplicatively, if there's a buff from a unit that adds 20% chance for 50% more dmg and the trigger misses, then it'll then roll the dice for the 40% chance for 50% damage given from the sphere.

the DAMAGE portion stacks additively, if both the 20% and 40% chances trigger then you get 50% more spark damage from the buff and 50% more spark damage from the sphere, as HQDominator said.

in total you have a 20% chance for 50% dmg, a 40% chance for 50% dmg, and a 8% chance to deal 100% dmg
