Feats

Most of the skill and general feats from Pathfinder can be used in Starfinder without any challenges. PCs should avoid feats that rely on incompatible equipment that might be difficult to obtain in the Starfinder setting. Alchemy has been supplanted by grenades and pharmaceuticals, while scrolls and wands have been replaced by spell gems and spell chips, and runes have been replaced by upgrades and the item grade system (commercial, tactical, and so on). Additionally, PCs should be aware of augmentations and tech gear that can make certain feats superfluous, especially those that provide new movement speeds and senses. These feats might still prove useful in campaigns where players don't have reliable access to their technology and for characters who can't spare the slots for additional augmentations and equipment upgrades.

Technology has also made some skill feats less useful. The Legendary Linguist feat still has its uses in campaigns exploring uncontacted worlds, but within the Pact Worlds, most PCs can get by through purchasing a translator app and investing in the lower-level Digital Ambassador skill feat. The theme of the campaign should always be considered. For example, players investing in Survival will appreciate being told beforehand that the campaign will likely not include wilderness adventures but might include some interplanar or urban survival.
