After getting this character I'm noticing that the character will lose the skill bar when his summon dies, this shouldn't happen because it takes him twice the time to let him summon again. He can't do anything else without his summon and he gets punished by not using the skill when the summon dies, it doesn't say anywhere that this happens but it does in battle if you look closely on his skill bar when his summon dies he can't refresh it
Not sure if this is intended because it's not in the skill description
