Imperial Inspiration [Human]

Once a day you can give an extra d8 to an ally. This ally can use this d8 for any attack, damage roll, saving throw or reaction to add to their CA if they are attacked. The ally must nevertheless use it within one minute after this feat is used. You regain all the uses of this trait after a long rest. You gain a new use of this trait at levels 5, 10 and 15 (up to 4d8 per day therefore).
