Argent Gliders

Wondrous item, rare (requires attunement)
  These meticulously crafted boots imbue their wearer with the nimble grace of the majestic silver dragon. Made by the elven smith Brimbor to honour the Forgemaster, they are always comfortably cool and a snug fit, enchanted to perfectly adapt to any type of terrain or activity.
  These boots have 2 charges and regain all expended charges daily at dawn.
  Ice Glide. When you step onto slippery terrain, such as ice or that created by the grease spell, while wearing these boots, magical blades of frost instantly form under your feet, allowing you to glide smoothly and easily on the hazardous ground. While these blades are out, you ignore difficult terrain caused by slippery terrain. In addition, while on that type of terrain, you have advantage on Dexterity saving throws, you automatically succeed on saving throws made to avoid falling prone, and your walking speed is increased by 10 feet.
  Slip and Slide. As an action while wearing these boots, you can expend 1 charge to stomp your feet on the ground and release a burst of chilling magic that freezes the ground within 15 feet of you, covering it in a thick layer of slippery ice and turning it into difficult terrain. When the ice appears, each creature standing in its area must succeed on a DC 15 Dexterity saving throw or fall prone. A creature that enters the area for the first time on a turn or ends its turn there must also make the saving throw. This effect lasts for 1 minute, after which the ice melts away.
  Uncommon variant. Reduce the save DC to 13. The boots have no charges, and using the Slip and Slide property costs no charges, but once that property has been used, it can’t be used again until the next dawn.
  Very Rare variant. Increase the save DC to 16. When you use this property, each creature in the area also takes 4d6 cold damage on a failed save, or half as much damage on a successful one. A creature that fails subsequent saves doesn’t take this damage
