Diablo 1 HD Hellfire Mod | Awake

Hello I started to play this mod 2 days back. I realized I can't repeat mushroom quest (probably), shrines are working completly different and elixes are only buffs.

Is there any other way how to permanently increase your stats or should I spend my points more carefully?

Yes - level up.

Obviously I meant some other repeatable way.

Quests that increase stats

-The Infestation of the Worms (level 5)
-The Black Mushroom (level 9)
-The island of the sunless sea (level 12)
-The lost treasure (level 13)

I also heard somewhere that when you reach level 60, all your points can be redistributed.
