Hello,

I finished the game once, a long long time ago. I just came back to the game and saw there are a lot of Mods.

Which Mods should i pick (more endgame / classes / skills / balance / items)? are they all compatible?

Generic Rewards - Multi classmod fix
Skill Points x2
TL2-ACE
TL1CP
Variant Classes
FEP+ (Kensei's passive Fine Control was never fixed; otherwise bug-free)
Dungeon Challenge ReMod
Adventures II (access this after the Mapworks otherwise it's a one-way portal)
Synergies
Abysm

That maximizes both classes with maps and is as compatible as I'm aware of.
5 mods there add more classes (50 more mod classes; as bug-fixed as possible).
2 mods there re-balance some vanilla-class skills (I prefer Ace over Synergies).
5 mods there add new items (mostly for classes).
5 mods there add more maps (for endgame).
3 mods there re-balance the game (helps survival; Synergies adds more enemies)
I left out Essentials to maintain compatibility with Ace's Stash and it's Act_05 access.

The mods listed by steffire are all good choices! All I would add is (1) be aware there is a 10 mod limit imposed by the game launcher and (2), since you asked about compatibility, custom class mods do generally play nice with each other. But the mods which add a lot of *other* endgame content may conflict with each other.

If you follow steffire's suggestion and go with only one choice between ACE or Synergies, you can try them out separately first.

If you go with Essentials for its QOL features it has to be above either ACE/Syn and, in the case of Synergies, you should also add the Essentials-Synergies compatibility patch mod on top of them both.

Oh be mindful that games started with one set of mods may not load (and may even crash your game) if used with another set of mods.

Although mod-packs (mods that are merges of many mods) tend to work around the 10-mod limit. Usually the mod-merges don't play well together if they include Inventory mods.

End-game content mods are compatible if it's map-related usually because the map-mods are located separately in the game-world.

Players who play both Synergies and Ace together recommend that new characters be created if both mods are used together to prevent issues.
Although either mod can be tested separately.

Essentials and Ace have these issues when together:
If Essentials is below Ace then the Stash doesn't function (Shared Stash is fine).
If Essentials is above Ace then the only portal to Ace's Act_05 is blocked.
I'm currently requesting a work-around for the portal issue.

The mod-unbinder (a workshop mod) can be used to try and salvage items from a mod-character save that is crashing after removing a binding mod like Synergies.
Otherwise the harsher method to remove the crashes is to delete the entire mod-save folder while the mod launcher is on screen then enter / exit the game.
