I don't have my starter rulebook handy, but, can they be Outwitted?
I believe the answer is yes, just like the Flight and Carry Abilities, but I just wanted to be sure.

Cheers.

All abilities except team abilities can be Outwitted, yes.

Just keep in mind that you're countering the abilities, not the symbols. If a feat prerequisite had the crosshair attack symbol or striped shield defense symbol and you use Outwit to counter Sharpshooter or Indomitable, it would not prevent the feat from being usable.

Great, thanks for the responses, and Rep to you 2.

Cheers.

EDIT: You must spread some Reputation around before giving it to Quebbster again.

Sorry , I'll get you for it though

Giant Size, Colossal Size and Multi-Attack cannot be countered either.

Cap'

Indomitable and Sharpshooter can be Outwitted. The only Combat Abilities / Special Abilities (as defined on page 17-18 of the FF rulebook) which cannot be Outwitted are Giant Size, Colossal Size, and Multi-Attack. Capture may be countered with the right die-roll.

It requires a single use of Outwit to counter each Ability, even if more than one Ability is granted by the same symbol. Most notably, the symbol provides Flight, Carry, and Move and Attacked; each must be Outwitted separately.
