Borrowed Grace — ruling 1

You choose all of your modes at once. You can’t wait to perform one mode’s actions and then decide to choose more modes.

Borrowed Grace — ruling 2

You can’t choose any one mode multiple times.

Borrowed Grace — ruling 3

If two of the chosen modes of an escalate spell target a creature, you may choose the same creature for each mode’s target, or choose different creatures. The same is true if the chosen modes target a player (or opponent).

Borrowed Grace — ruling 4

If one target of an escalate spell becomes illegal, the other targets will still be affected. If all of the targets become illegal, the spell won’t resolve.

Borrowed Grace — ruling 5

Effects that reduce the cost of spells reduce the total cost, including any escalate costs added.

Borrowed Grace — ruling 6

If an effect allows you to cast a spell that has escalate without paying its mana cost, you pay escalate costs for that spell if you choose more than one mode.

Borrowed Grace — ruling 7

Additional costs don’t affect a spell’s mana value.
