It means that his SBB might trigger a debuff on your enemies that increase the amount of damage they receive through Spark, and this debuff (of 25%), stacks with all the spark damage boosters you might have applied to your team. So, if you have a unit with +100% spark damage, and the enemy has the +25% spark damage debuff, you will deal +125% on that target on that specific turn.
