Alchemist Discoveries

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.
