Player Characters creating finite magical items

Divine spell casters need Crafts Domain ●● to make potions and scrolls. They need ●●●● to make staffs and wands.
Arcane casters need the appropriate Merit for the item they intend to craft.
Divine spell-casters roll Manipulation + Crafts in an extended roll to create finite items. Arcane spell casters roll the same attribute + casting attribute they would normally roll, but subject to a different difficulty.
Every three successes garnered creates one potion, one scroll, one wand charge, etc. If a player rolls five successes on a single roll they have created two potions. If the character rolls more than five successes, the character gets two potions plus some carryover to their extended roll.

● base difficulty 7, 2 hours per each roll
●● base difficulty 8, 4 hours per each roll
●●● base difficulty 9, 6 hours per each roll
●●●● base difficulty 11, 8 hours per each roll
●●●●● base difficulty 13, a full day per each roll

The base difficulty is subject to many potential modifiers (see the bottom sidebar). Characters need to lower the difficulty to at least 10 before they can even try to make magic items. Related ability modifiers are cumulative but they cannot lower the difficulty below 4.
Each roll consumes some reagents (see the top sidebar)
