==Example of Stacking==
*Assuming Devoted Yasna Armaiti is equipped with Delusion Device and her "Add to SBB (Boosts Spark damage for 3 turns)" SP option is the only option unlocked, Armaiti will have a total spark damage bonus of 445% during the first two turns, but a total spark damage bonus of 345% from Turn 3 onwards.
**Armaiti's SBB provides a 125% boost to Spark damage for Earth units
**Armaiti's SBB provides a 220% boost to Spark damage, provided the SP option was unlocked
**Delusion Device provides a 100% boost to Spark damage during the first two turns
