The spell Acid Splash describes itself as:
You hurl a bubble of acid.
This is followed with the damage description:
1d6 acid damage. This spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
The item Vial of Acid is simply referred to as acid and notes its damage as:
2d6 acid damage.
The question is can the caster catch the bubble in a flask or container
(they would then later pour it into a vial)?
Can the caster simply drop the bubble instead of hurling it?
If the caster can store the acid then would it deal damage equal to Acid Splash or to that of vial of acid?
If it deals damage equal to Acid Splash then what tool proficiency would be required to refine it
(Artisan's tools (alchemist's supplies), Herbalism kit, or Poisoner's kit) ?
