Renewable Mark of Blood

[Limas Venomscale]

If the spell Mark of Blood was made into an Oil and placed into a Bountiful Bottle for a Mark of Blood 1/day, would it work ?

Overall do I think such an item could be made. Yes, but note it requires a Mythic Crafter, would have to work on Oils, Elixirs and other non-potion liquids which requires Craft Wondrous not Craft Potion and generally Oils, Elixirs etc. are more costly per dose so the item would need to account for this in its crafting.

And like any item, particularly non-standard items, it would require the DMs approval for a PC to create.
