A) I equip a champion (draksar augmenter) with an equipment which gives a cooldown ability (yetihide cape gives frost cone). My champion has 10 ap. B) I use said cooldown ability (ap cost : 4) and cooldown is set to 3. My champion has 6 ap. C) I use binding reflection on equiped champion. Cooldown is set to zero and I can use frost cone again (ap cost : 4). My champion has 2 ap remaining.
Another Binding reflection exploit : using it on a unit with initiative gives it the ap bonus points back again. A) I have a unit with initiative and zero ap stored (already deployed and used ap already) B) Use Binding Reflection on it C) Initiative unit gains ap as if it was just deployed
