Does Irelia Graceful (purple) reduce REPEAT cost?

Ruling: Yes, Irelia Graceful can reduce the REPEAT cost because REPEAT is an optional additional cost, and discounts can apply to additional costs. However, the discount only applies once per spell, as REPEAT repeats the spell's effect but is not itself a new spell.

Nuances:

• REPEAT is not considered a spell itself, only a repeat of the spell's effect
• The discount applies only once total, not separately to the REPEAT cost
