In Diablo 2: Resurrected, many of the gear players can find have many different stats, and Light Radius can be confusing as gear can actually have both positive and negative numbers attached to it. Meaning playing could be using a device that both gives them Light Radius and takes it away.
The only effect Light Radius has in Diablo 2: Resurrected is the amount of light around the character in dark areas. This could be in dungeons, caves, or above ground locations at night. There is not much of an advantage to having either a big Light Radius or a small Light Radius, and seems to be just a leftover mechanic from the original Diablo. Although it can be helpful when finding hard-to-find dungeons.
In the first Diablo, the increased range of light alerts enemy D2R Items characters more quickly. This has resulted in some players equipping gear with as small a radius as possible so they can sneak past some enemies. It was useful in the original sequel for illuminating the environment to spot loot and high-level enemies, but that's not an issue in Diablo 2: Resurrected, thanks to updated visuals.
If having a larger light range does appeal to players, they should know that their base stats start at 13 and have a maximum cap of 18. This means they only need to equip items that add up to +5. Nothing can be done beyond that. There are also many hidden game tricks like this that players need to be aware of, like how to reset skills and stats in Diablo 2: Resurrected.
In Diablo 3, Light Radius became redundant as the game was much brighter than its predecessors. The devs also didn't restore the ability to Buy Diablo 2 Resurrected Runes sneak into small radius enemies, so this data is completely broken. Additionally, if players realize the importance of Diablo 2 Resurrected Items, players are advised to visit MMOWTS immediately and place an order. They are ready to offer players the cheapest D2R Items.
