In September 2017, ZOS reworked Master and Maelstrom weapons. What they did was remove "unique enchantments" that the items possessed, and reclassified the skill-specific weapon modifiers as "sets." This allowed players to now put enchantments or slot poisons on their Master and Maelstrom weapons, while still maintaining the skill-specific weapon modifiers.
At the time, there was no such thing as a 1 pc bonus on Arena/Trial-style weapons. This led ZOS to say that the stat bonuses that were on the weapon enchantments (for example, Maelstrom 2H gave 189 weapon damage) were
"extraneous stat bonuses," so they removed those stat bonuses from the weapons to maintain the standards at the time.
The Master and Maelstrom unique enchantments have been rebuilt as Item Sets, with the new Asylum Weapons following suit as an Item Set and not an enchantment. This means you can now safely enchant and re-enchant these weapons, and still gain the special ability-altering benefit.
Developer Comments:
Due to the fact these items can now be enchanted or poisoned normally, their extraneous stat bonuses have been removed. For example, the Maelstrom’s Greatsword no longer adds 189 Weapon Damage on top of the modifier to Critical Charge.
The Master and Maelstrom One Hand and Shield Item Sets now require you to use both the One Handed Weapon and Shield together. Since the shield did not need to be paired with the One Handed Weapon originally, a brand new shield will be mailed to you for each One Handed Weapon you currently possess.
It’s also worth noting that you will still be able to back bar weapons, such as the Maelstrom Bow or Inferno Staff, and still receive the bonus from them when their abilities are active.

At the time, ZOS could not have predicted the future and realized that they would be adding 1 piece bonuses to Master and Maelstrom weapons to bring them up to standard with other Arena/Trial weapons that contain 1 piece bonuses and, at the time, had yet to be added into the game. It is understandable,
at the time, that ZOS would describe those stat bonuses on Master and Maelstrom weapons as "extraneous." But now, in 2020, stat bonuses are no longer "extraneous," as evidence of ZOS' intent to apply 1 piece bonuses to Veteran Master and Veteran Maelstrom weapons.
Simply put, ZOS, you removed stat bonuses from Master and Maelstrom weapons because you once described them as "extraneous," which they were for the standards at the time. But now that stat bonuses are no longer "extraneous," your decision not to update the existing weapons is inconsistent with the updating and balancing standards you have already established with current Master and Maelstrom weapons. If we have learned anything about your balancing/updating in the past year-plus, it is that you love standards. Follow your own standards and update the current Master and Maelstrom weapons.
