Could look something like this.
-2 Ritual (Crafting)
-2 Refinement (5 Enchanted Item Slots; 3 Potion Slots)
Total refresh cost -4
Focus Item from the two slots of Ritual (+2 crafting Strength)
combined with a high Lore skill, this gives you nicely powered Enchanted items and potions, (potions can be a lot of things, not only drinks, so they can model magical explosives or other stuff as well) while retaining enough Fate points to spend for instant potions.
Depending on if you want the character to have more fixed gizmos, or if he's more supposed to whip something up on short notice you can modify the number of enchanted item vs. potion slots.
