Thanks for the reply
If I apply aid to a power attack or to the eidilon ability furious strike it become powerfull, but if it's applied to dual strike or dragon frenzy it's a bit watered down... well if it's the rule it's the rule I guess
I have a Summoner build and I wonder if I can help my dragon on his dragon frenzy attack.... will the aid be apply to all 3 attack?? Thanks for your knowledge
