Hobgoblins, being loathe to wield "elf magic," rely on the Alchemist class for their arcane powers, but I noticed that neither of the two NPCs with Alchemist levels that the part runs into in the first book (Tukang from Oreld's Fine Shop and Yissti from Camp Red Jaw) possess formulae books. I assume this to be an accidental omission on the part of the author.
My group running through this adventure contains an Alchemist so he is always on the lookout for new formulae. I was thinking of including a formulae book in one of Yissti's locked chests. Noting that the hermit Veld possesses a spellbook with all 0- 1st- and 2nd-level spells from the Core Rulebook, I was considering taking that same approach with Yissti's formulae book - including all formulae of 1st- and 2nd-level from the Core Rulebook and APG.
Does anything think that would be problematic?
