Magnus edition for an extra fiver is worth it imo as you get the season pass. You get an extra chapter (nice reward item) and an additional skill tree which is very nice for some builds. Loot boost for shards is cool too.
Don’t bother with the other itty bitty DLCs.
Bargain in the current sale - I prefer it to most other Diablo clones out there. The builds on fextralife were v useful if I remember correctly.
