Yon Empty Flask. Card Artwork. Equipment Class: Magical item... when full.
This is from a series of card artwork I'm working on with a friend in getting his card party game off the ground. The game, Thy Dunjon Quest, is a party game utilizing elements of charades and blackjack for players to go one mock quests and encounters while gambling their gear based on success or failure.
Yon Empty Flask is essentially the potion bottle that you needed... if it had full contents. I originally was drawing a literal flask, but my friend was leaning more towards a potion bottle, so I adjusted accordingly. The angle is actually from the scanner, and I liked it as the drop coming out of it works better at a downward slant than an upright tilt.
