I expect nothing lower then 15, if owlcat a team much smaller then larian where able to make 20 levels and mythic paths in a game, larian a team with more then 300 people have no excuse to not do so. 5th edition unlike pathfinder has everything so streamlined the devs can just copy and paste the code and have it work- with minor changes to adapt to their game engine. We have modders in the community already of 2-3 people who already added level 20 spells in game. There is 0 excuse for larian.
