Borrowed Hostility

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).

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.

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