Diablo II: Resurrected players love freedom—freedom to theorycraft, freedom to break the meta, and yes, freedom to bind Teleport to the left mouse button like it’s 2003 and nothing matters. The Unlock LeftRight mod does exactly that. It unlocks the long-standing restrictions on assigning active skills to left- or right-click, giving you the flexibility Blizzard never intended but absolutely should’ve.
Crafted as a small but game-changing tweak, this mod cracks open D2R’s archaic skill-slotting logic and lets you slot almost any active skill on either mouse button. The result? Faster gameplay, smoother builds, and a whole lot of "Why wasn’t this always possible?"

What the Unlock LeftRight Mod Actually Does
At its core, the mod removes restrictions that block certain skills from being placed on left-click vs. right-click. In other words:
If it's an active skill, you can put it wherever you want.
No more “This skill cannot be assigned to that button.” No more fighting the UI when your muscle memory says one thing and the game screams another.
What Is Unlocked
-
All common active skills
-
All classes (yes, even Sorceress spammers and Javazon mains)
-
Skills like:
-
Teleport
-
Nova
-
Fireball
-
Charged Strike
-
Freezing Arrow
-
Slot them left. Slot them right. Live your best ARPG life.
What Remains Restricted
Auras and Passives—and not for lack of trying.
The mod creator attempted to free Paladin Auras, but Diablo II’s aura logic is hard-coded. Sure, you can slot an Aura on left-click... but it won't actually activate. They remain tied to the core game loop.
For auras to work on left-click, they’d have to behave more like:
-
Battle Command
-
Battle Orders
—buffs you activate once and forget.
But that would rip the identity right out of the Paladin’s design. So the mod leaves them untouched, preserving class integrity while freeing up everything else.
Why This Mod Feels So Good to Play
If you've ever played Sorceress, you know the pain:
You want Teleport on left-click for movement, but also want a big destructive nuke ready to go instantly. D2R’s default system forces awkward compromises.
Unlock LeftRight fixes that friction point completely.
Players can now:
-
Smoothly spam Nova or Blizzard on either button
-
Move and cast on preferred click layouts
-
Build hybrid setups without fighting the game
-
Make older builds feel modern again
It’s the kind of quality-of-life change Blizzard would never risk adding officially—yet once you try it, it feels natural.
A Simple Mod With Big Impact
Despite its effect on gameplay fluidity, the mod itself is surprisingly small. The creator describes it as “a simple piece of code,” made mostly for convenience while playing Sorceress. And that’s the magic of PC modding: small tweaks can make a legendary game feel renewed.
It respects the core structure of Diablo II while expanding freedom in a way that feels long overdue.
If you’ve ever wished for more intuitive control over your skills, this is one of those must-have D2R mods.

Final Thoughts
The Unlock LeftRight mod doesn’t try to overhaul Diablo II. It doesn’t add new runewords, enemies, or crazy difficulty spikes. Instead, it gives players something far more valuable: control.
Control over how you play.
Control over how your skills behave.
Control over the moment-to-moment feel of combat.
It’s the sort of mod that becomes an instant staple—quiet, powerful, and impossible to go back from.
