Guide talk:Thrileon's Guide to Double alchemy crafts
I think you don't really need the Cleric levels; Guidance isn't really necessary if you're a Halfling with +13 to Medicine and Advantage. Transmutation Wizard 2 / Any Bard 10 gets you Experimental Alchemy, Expertise in Medicine at Bard 3, Enhance Ability at Bard 3, 2 ASIs at Bard 4 and 8 for +2 Wisdom each. This build almost guarantees a successful check. The only way to fail would be to roll 2 1's with advantage and then roll another 2 1's for the Halfling Luck rerolls.
Level 3 eay Act 1 method
This can be improved upon by a lot with a little better optimization.
You can do the exact same chance with using 2 characters one level earlier. Hire Brenna Brightsong at level 9 hireling and a level 1 Cleric/Druid or a level 3 Tomelock for Guidance, or level 3 Bard/ Cleric/ Druid/ Sorcerer for Enhance Ability. Use Wizard 2 (Transmuter) for the ability, Rogue 1 for expertise, Fighter 6 for the 2 ASI to bring up to Wis 20 on the Halfling hireling.
If you want to stack Guidance along with Enhance Ability, you can just use 2 other characters to cast them and/or use one other character & loan/use some of the Magic Items that grant the spell(s). There are items that can be found very early game that help. One allows anyone wearing it to cast Guidance, and another gives the same effect that also stacks with Guidance if you are shapeshifted/disguised (netting +2d4 instead of +1d4).
With those items and one other character to cast Enhance ability you can have roughly a similar chance at level 3: The Halfling Transmuter 2 / Rogue 1, & one level 3 of a class that can cast Enhance Ability (Bard, Cleric, Druid, or Sorcerer). 7 +2d4 with advantage and Halfling Luck at level 3. 99.64% only a 0.11% worse chance than the author’s method, 7 levels earlier.
At level 9 that is virtually a guaranteed success at 99.999375% success, with only 1/160,000 chance of failure. And that is where it caps out at.
TL;DR: Level 3. Use Brenna Brightsong and make her a Wizard (Transmuter) 2/ Rogue 1; have her take Expertise in Medicine proficiency and have her take disguise self as a spell; wear the Shapeshifter’s Boon ring and shapeshift her to anything else; cast Guidance and Enhance Ability using 1 other character and the Silver Pendant or 2 other characters.
