Benefit: You receive a +2 bonus on Craft (alchemy) checks, and you may create mundane alchemical items much more quickly than normal. When making poisons, you can create a number of doses equal to your Intelligence modifier (minimum 1) at one time. These additional doses do not increase the time required, but they do increase the raw material cost.
In addition, whenever you make alchemical items or poisons using Craft (alchemy), use the item’s gp value as its sp value when determining your progress (do not multiply the item’s gp cost by 10 to determine its sp cost).
At 18th level, an alchemist can create alchemical items with almost supernatural speed. He can create any alchemical item as a full-round action if he succeeds at the Craft (alchemy) check and has the appropriate resources at hand to fund the creation. He can apply poison to a weapon as an immediate action.
My understanding is that Instant Alchemy would probably take over the Master Alchemist's second ability in terms of how long it takes (full-round action), but was wondering if anything happens with the second ability from Master Alchemist to make up for this loss in Feat power? Or does it just turn into a worse skill focus at Alchemist level 18?
