You must always pay the surge cost of the ability re-triggered by means of Inner Fire; the card simply (where simply is not that simply, it's really a strong card) allows you to trigger the special ability more than just once / roundHer reading has already been corrected by official source in a later thread, but I'll reiterate it here for forum consistency (a bit OCD I know).
Inner Fire: Once per combat round as a combat action, you may exert to trigger the surge ability on your hero. This allows you to trigger that surge ability more than once per combat round.
1. Exerting triggers the ability. You do not have to spend surge symbols like you usually do. This is Inner Fire's primary effect; you can use Inner Fire to trigger your surge ability even if you have no surge faces casted. The fact that this allows an ability to be used twice is a bonus effect.
2. If you use Inner Fire on Master Thorn's Mind Meld, or Battle Robes' (A11) Channel, this allows you to double/ quadruple the damage.
3. Yes, the card is too cheap and the ability is broken. Good luck drawing it.
