Using Bow Bash as an example.

What does it mean when I get a new ability such as Bow Bash 2 and I put it in my combat bar but I can't use it?, at the bottom of the ability it says
"Lack the consumables for this ability"

I have several version 2 abilities that are doing this in archery, and I have all the prerequisites to be able to use them. Just dont understand. Please help!
