I just picked up Summoner again after not playing one for ages. I last played a SMN when it had DoT skills and Fester spread them to other enemies... But it has changed big time it seems. What bothers me though and I wonder if I am just missing something, Carbuncle no longer attacks AT ALL.

Despite having steady and Guard (of which Guard says no attacks until attacking or being attacked) it just stands there doing nothing. When I check it says I already have Guard up, but then Carbuncle should do attacks when I am attacking or being attacked...

The only Carbuncle that seems to do ANY attack, is when I temporarily summon Ruby. So what gives? am I missing something, or was the first Carbuncle rendered useless?
