Top 3 Multi-Button Mice for Diablo IV: G502 X, Naga, Scimitar

This is a buying guide for those who want to consolidate inputs like Skills, potions, and evasions to the mouse side when playing Diablo IV on PC. Blizzard officially supports remapping keyboard, mouse, and controller inputs. This article compares three products with different button counts and uses, based on official manufacturer specifications as of August 9, 2026. Using a multi-button mouse does not increase your damage output. The selection criteria are based on whether it can reduce the movement of your left hand or the burden of key operations.

Conclusion: G502 X if in Doubt, Naga or Scimitar if Consolidating to One Hand

If it's your first multi-button mouse, the G502 X is an easy choice. With 13 programmable controls, it can assist with major Diablo IV inputs and is the lightest of the three products at an official weight of 89g. For those who want to move more keyboard operations to the mouse, the Naga is a candidate; for those who want to adjust the front/back position of the side panel, the Scimitar is a candidate.

5 Items to Check for a Diablo IV Mouse

1. Number of Side Buttons Required

Diablo IV's Skill slots are limited, so 12 side buttons are not necessary for everyone. Write down the operations you actually want to move to the mouse, such as potions, evasion, forced movement, and the action wheel. If 4-6 buttons are enough, fewer buttons than a thumb-grid type can reduce mistaken presses.

2. Ease of Button Identification

During combat, you cannot visually confirm buttons. It's important whether you can distinguish buttons by their shape or angle from adjacent ones, and whether your thumb can reach them without bending too much. For 12-button models, it's safer to limit assignments to a few until you get used to them, then gradually increase them.

3. Wired or Wireless

Wired mice do not require charging or battery replacement. Wireless mice avoid cable drag but require a dedicated dongle USB port and battery management. The Naga V2 HyperSpeed officially offers up to 250 hours via 2.4GHz and up to 400 hours via Bluetooth. The Scimitar Elite Wireless SE offers up to 150 hours via 2.4GHz and up to 500 hours via Bluetooth when RGB is off. View these as upper limits that may vary depending on usage conditions.

4. Weight and Grip Style

The G502 X weighs 89g, and the Scimitar Elite Wireless SE weighs 114g. Beyond just lightness, the burden changes depending on grip style (claw, palm), and hand size. If you plan to play for long sessions, it's reassuring to check the thumb position and ease of lifting at a physical store.

5. Configuration Software and Compatible OS

For button assignments, you will use software such as Logitech G HUB, Razer Synapse, or CORSAIR iCUE. In environments where you cannot install additional software, such as on a work PC, check the extent of onboard memory and the initial setup method.

Logitech G502 X: Sufficient 13 Controls and 89g

This is a wired model featuring 13 programmable controls, a HERO 25K sensor, up to five onboard profiles, and a dual-mode scroll wheel. While not as many as a 12-button keypad type, its configuration is easy to handle for assisting with major Diablo IV operations. It is suitable for those who want a lightweight multi-button mouse without worrying about charging.

Note: There are models in the same series such as G502 X LIGHTSPEED and G502 X PLUS. Please confirm the product name as their connection methods, weights, and prices differ.

Razer Naga V2 HyperSpeed: 21 Controls and a 12-Button Thumb Grid

The official specifications list 21 programmable controls and a 12-button thumb grid. It supports 2.4GHz and Bluetooth and operates on a single AA battery. It is suitable for those who want to profile multiple build operations and shortcuts to significantly reduce left-hand key operations.

Note: Razer Synapse 3 is required for button assignments. With its right-handed ergonomic shape and high button count, accidental presses may occur more frequently until you get used to it.

CORSAIR SCIMITAR ELITE WIRELESS SE: 12 Position-Adjustable Side Buttons

Of its 16 programmable buttons, 12 are placed on the side panel, which can be moved forwards and backwards with the Key Slider mechanism. For those who want to match the length of their thumb, this is a more important feature than the sheer number of buttons. It supports 2.4GHz and Bluetooth, and configuration uses iCUE.

Note: The official weight is 114g, so it is not a lightweight mouse. The sensor and battery specifications differ between the SE and the conventional SCIMITAR ELITE WIRELESS, so please check the model number on the sales page.

Recommended Assignment Examples

If You Have Fewer Extra Buttons

• Side Front: Potion
• Side Rear: Evade
• Extra 1: Forced Movement
• Extra 2: Action Wheel

For 12-Button Models

Do not fill all 12 buttons from the start; use only the 4-6 buttons your thumb can naturally reach. When changing Skill assignments, do not change both the in-game key settings and the mouse software simultaneously; verify operation one by one. For reasons of terms of service and preventing accidental operations, it is generally recommended to set one button to one input, rather than using macros that automatically execute multiple operations.

Cases Where You Don't Need to Buy a New Mouse

• You are not having trouble with operations using your current 2-side button mouse.
• Keyboard operations are faster and cause no fatigue.
• You do not want to keep configuration software running in the background.
• You need a compact or left-handed shape, but the candidate products don't fit.

In these cases, first try in-game input remapping or Skill toggles. If the issue can be resolved by simply changing settings, a new mouse is unnecessary.

Pre-Purchase Checklist

• The right-handed shape and body size fit your hand.
• You have decided on the necessary number of buttons.
• You have decided on your preference for Wired／2.4GHz／Bluetooth.
• You can install the configuration software on your PC.
• You have checked the model number, warranty, and return conditions on the sales page.
