They are just giants. It's not like they have one more magic pocket for additional bracers. And yeah, that 3rd slot is just for stacking E9 bless bug.

Zamzummites are almost SCs, they are at least very good thugs. If they were cap only you'd have to choose between Adon and Zamzummite. And it would be a fair choice to make. And you'd be still left with non-cap mages other nations can dream of.

Zamzummites would be still probably the strongest recruitable fighters in MA. Way better than Jotun cap-only giants or other weak thugs.
