Stacking Expert Tracker

[Hodges]

If Kraven spends 6 power on two Expert Trackers, can he put them both on the same enemy character? And if so, will it give +2 dice for all allied characters that target that character?

You could use the superpower twice and both times choose the same character.

You will only get one additional die when attacking that character though because each character or object can only be effected by the same named effect once.
