To determine a spell's total cost, start with the mana cost (or an alternative cost if another card's effect allows you to pay one instead), add any cost increases (such as kicker), then apply any cost reductions. The spell's mana value remains unchanged, no matter what the total cost to cast it was.

If a spell's kicker cost was paid, the spell is "kicked."

The kicker ability doesn't let you pay a kicker cost more than once.

If you put a permanent with a kicker ability onto the battlefield without casting it, you can't kick it.

If you copy a kicked spell on the stack, the copy is also kicked. If the copied spell is a permanent spell, the token the copy of that spell becomes when it enters is also kicked.

If a card or token enters as a copy of a permanent, the new permanent isn't kicked, even if the original was.

If more than one mode is chosen, perform them in the order written. Nothing can happen in between, however, and no player may choose to take actions. Any abilities that trigger will be put onto the stack after the spell has finished resolving.

If any targets become illegal, the other targets will still be affected as appropriate.

If the second mode is chosen and each creature the target player controls has negative power, that player doesn't gain or lose life.

If either target creature is an illegal target as Inscription of Abundance resolves with its last mode chosen, no creature will deal or be dealt damage.

If you kick Inscription of Abundance, you can't choose any one mode more than once.
