Discoveries







At 2nd level, and then again every 2 levels thereafter (up to 18th level), an alchemist makes an incredible alchemical discovery. Unless otherwise noted, an alchemist cannot select an individual discovery more than once. Some discoveries can only be made if the alchemist has met certain prerequisites first, such as uncovering other discoveries. Discoveries that modify bombs that are marked with an asterisk (*) do not stack. Only one such discovery can be applied to an individual bomb. The DC of any saving throw called for by a discovery is equal to 10 + 1/2 the alchemist’s level + the alchemist’s Intelligence modifier.

At 20th level, the alchemist makes a grand discovery. He immediately learns two normal discoveries, but also learns a third grand discovery chosen from the list below, representing a truly astounding alchemical breakthrough of significant import. For many alchemists, the promise of one of these grand discoveries is the primary goal of their experiments and hard work.

Note Discoveries marked with an asterisk (*) do not stack—only one such discovery may be applied to a single bomb.
