Alchemy recipe
Expert's Truth Spellbook
Expert's Truth Spellbook is crafted with Alchemy at proficiency 15 from 1 × Splendent Truth Spellbook, 5 × Expert's Refining Stone, 6 × Fine Ruby Gemstone, 3 × Fine Odyle. A craft succeeds 76.8% of the time at your recipe's level and up to 94.6% with a higher proficiency. After a success, a combo (25% activation) can turn it into Expert's Splendent Truth Spellbook: 22.39% per craft at best.

Odds and real cost
Our calculation from the recipe's chance table: crafts per success = 1 ÷ success chance; per combo result = 1 ÷ (success × activation × combo craft). Parts that a recipe can make are expanded too, each crafted at your proficiency minus its own recipe level. Assumed: a failed combo craft still gives the normal item (the game only says a successful combo replaces it), and one proficiency level for every profession.
