Here's the text from Spell Reader, which covers the making of runes and talismans:
Perform a standard 2d6 Test to successfully read the scroll. When successfully read, the magic of the scroll takes effect, and the scroll turns to dust. If the Test is failed, the magic is not invoked and the scroll is unaffected.
You have mastered a few arcane words, inscribed into your talisman. Test to craft spell scrolls using words of power, failure requires you start over. The more words combined the greater the effect and the more costly the scroll and longer it takes to craft. Spells crafted only using mastered words tests at advantage.
| # Word | 1 (Rune) | 2 (Talisman)
|
| Minutes | 1 | 10
|
| Gold | 1 | 10 |
Scrolls could be extended to include 3 or 4 Words, but I don't remember what the stepping was.
(I don't think it was a full 10x each step, but could be wrong.) Actually, doing a full 10x each step should work just fine. 100 minutes is just over a hour and a half, and 1000 minutes is basically a day. So, it does work out OK, though 1000 GP scroll or potion should be absolutely outrageous! (Like blow up an entire building or raise someone from the dead.)
To transition that to alchemy, make that Components instead of Words and it should transfer fairly directly. So, with just the base Trait he can make potions, oils, and bombs that take 1 or 2 Components. He has to take Advanced Alchemy (or whatever) as a Prestige Trait in order to make items that take 3 or 4 Components.
