So what you guys think ? I was thinking to change my first gladiator with the 992gold, or with 958 both are good, but hey the 3rd is not bad to or I can change both of my gladiators ? Maybe I can buy 1 more space for extra gladiator ? and this way I can buy the first and second slave ? but is it worth for them to buy extra space ? I'm playing without buying Trophies and not gonna start buying them ever, I only have 18 Trophies from quests and arenas and was saving them for expanding the inventory size to 2, need advice pls
Edit: and please tell me what race and speciality should make them
