Angulotl Oil

This sticky translucent unguent is thick and heavy
in the container, but it flows quickly when poured.
Applying the oil over the user's body takes 2
minutes. The affected creature then gains the
Slippery effect, giving disadvantage on opportunity
attacks against them for 2 hours or until the oil is
washed off. Alternatively, the oil can be poured
on the ground as an action, where it covers a
0-foot square, duplicating the effect of the grease
spell in that area for 2 hours.
