This site should hopefully have anything you need to know or have found out during the campaign.
Brief overview: You pick 3 sacrifices (monster parts) to form a class and get abilities and spells, and then you enter the tower (Kind of like SAO) to kill stuff and do quests and level up.
Most useful pages:
[[Classes]]
[[Combat]]
[[Examples]]
[[Spells]]
We round numbers in this.
You start at level 0 in [[The Outside]]
Each square on a map is 1m
We do milestone levelling (Basically I say when you level up)
