Potion, uncommon
This sticky black unguent is thick and heavy in the container, but it flows quickly when poured. The oil can cover a Medium or smaller creature, along with the equipment it's wearing and carrying (one additional vial is required for each size category above Medium). Applying the oil takes 10 minutes. The affected creature then gains the effect of a freedom of movement spell for 8 hours.
Alternatively, the oil can be poured on the ground as an action, where it covers a 10-foot square, duplicating the effect of the grease spell in that area for 8 hours.
Notes: Control, Movement, Utility, Consumable

Posted May 14, 2020But what would the DC for the grease be after applying it to the ground... it'd make no sense for the 'Slipperiness' of the Oil to shift depending upon a person's spellcasting modifier... and what if a non-spellcaster poured it on the floor?

Posted May 15, 2020Apply the same DC as if it were a scroll for the minimum level needed to cast the spell. See scrolls in the DMG.

Posted May 15, 2020So DC 13 Dex save, according to the table on Spell Scroll. Is that homebrew or in the rules somewhere?
Also that is actually really good for a mundane item, it is better in everyway than the action from Ball Bearings (bag of 1,000) (not to mention that the oil has explicit alternative uses):
“Slick grease covers the ground in a 10-foot square centered on a point within range and turns it into difficult terrain for the duration.
When the grease appears, each creature standing in its area must succeed on a Dexterity saving throw or fall prone. A creature that enters the area or ends its turn there must also succeed on a Dexterity saving throw or fall prone.”
If only it had an explicit cost...

Posted Jun 9, 2020It's a potion. As in a consumable magic item
There are cost suggestions in the DMG and Xanathars for buying and making them

Posted Sep 9, 2022Except it’s an uncommon, consumable magic item, and not something you can find at any mundane item shop in the world for 1 gp. At best you could hope to find it for a couple hundred GP at a DM’s homebrew magic item shop.

Posted Nov 28, 2022It may well be better than that *action* in the moment, yes. But, if given the choice, I would be likely to select the bag over the potion assuming cost and all other factors were equal. This is because the ball bearings can at least potentially be recovered after they have been utilized and then reused, possibly indefinitely. The Oil of Slipperiness, though, is usually a single-use substance.
