The following discoveries can be selected by Alchemist or Legendary Alchemist^LAl characters.

Bomb Discoveries

Bomb Admixture (Ex)

Your bombs blend multiple concoctions into a deadly weapon. You may apply two [substance] infusions to a bomb (if a legendary alchemist) or may apply two talents marked with * to a bomb (if a normal alchemist) rather than just one. If this would cause the bomb to deal multiple different damage types, the bomb deals half of its damage as one type and the other half as the other type. You may only apply the non-damage effects of one of the bombs unless you take this discovery a second time.

Grenade Bombs (Ex)

Your bombs are designed to resemble conventional munitions. You may use your bombs with any equipment or feat that can be used with grenades (for example, they can be loaded into weapons such as grenade launchers and minelayers, made into grenade arrows, or used in conjunction with class abilities such as grenade expert or terrifying blast). If you are not already proficient with grenades, you become proficient with grenades.
