Other Equipment

Most other varieties of equipment in Pathfinder have Starfinder equivalents, and it should be relatively simple to adjudicate their use. Spell gems can function like scrolls, serums like potions, and so on. You should always warn your players that specific interactions of converted equipment with other items and feats are always subject to change. For example, you might rule that the alchemical flasks awarded by defeating a time-displaced alchemist can function as detailed in the appropriate Pathfinder source book, but you should also keep in mind if such items will be a suitable reward and could perhaps instead choose to have them operate as grenades. It's usually best to wait until after a session to make any on-the-fly adjustments. Your players will likely remember the encounter where they took out a pair of vesk honor guards with a glue bomb fired out of a fireburst chamber!
