I can guess other abilities, but I don't know about the charisma. Is it to make the minions stronger?

I'm currently level 16 but for some reason the level 2 map Gloomy Path is still marked as incomplete even though I've cleared it numerous times.

Took the main quest to get the solar shards and then it was like 'Well done you've got the solar shards here's the last boss!" and my level 8 wizard got splattered across the hall. Kind of ruined the game as I have no way of going back to the castle now except to fight the final boss......

Not only the dude summons the hardest skeletons all the time like 5 in one go, hits like a truck with non stop spamming, takes forever to kill He can also easily teleport next to you and 1 hit KO you in case you're casting something and don't even have time to teleport away. What kind of trash game design is this, who the hell thought this would be enjoyable for anyone?...

I encountered this near the beginning of the adventure and I damaged the chest to the point of oblivion. No loot
