Hopefully patch 8 will finally include level 5 so we can actually test something that really needs to be tested (multi-attack and level 3 spells) as there's definitely more than enough experience to reach level 5 (and possibly level 6) within Act 1.
There's enough XP in the existing content to reach between level 8 and 9 ( or 9 and 10, I forget which ) if you are a completionist. There is a mod called "LevelUp" on the nexusmods.com web site that allows you to continue past level 4, but it takes a while to update the mod after each new patch.
To be honest, multi-attack is a non-event as far as testing is concerned, and most higher-level spells have not been implemented, so testing above level 4 with this mod is hit and miss. It does add class features where that is possible and there are other mods that add classes/subclasses/races that are not yet implemented. None of that is supplied by Larian, so it is just a bit of fun to add them after you have become bored testing a new patch.
