Without access to advanced technology, many Starfinder classes have to rely on Pathfinder equivalents to properly function. In the Lost Omens setting, players might need to rely on technology from specific niche sources like alien technology from Numeria, relics from the Jistka Imperium, and experimental weapons forged in Alkenstar. Alchemical and magical solutions might also exist, but the item's traits would need some adjustment. Groups looking for a challenge might want to deny their players access to solar charging stations and might demand that players spend downtime to maintain or recharge their gear, or else incur the
glitching condition on a critical failure. While many of Starfinder's items aren't easily integrated into most Pathfinder campaigns, there are opportunities to use this alien technology in your game without having to convert everything into a magic item equivalent, guidelines for which can be found in
Anachronistic Gear.
Early on in a campaign, time-traveling characters might struggle to make ends meet, unless they happen to be antique coin collectors. The balance on a credstick is meaningless in a civilization without computers, but even the most mundane tech gear could be worth a king's ransom to collectors. A spare firearm,
jet pack, or even
datapad is likely worth many times more than what it would be in Starfinder, assuming you can find the right buyer. This kind of exchange can be especially helpful if a Starfinder character is being introduced to a Pathfinder campaign above 1st level, but the player wants the character to be completely out of their element. It can also serve as a fun narrative device when an eccentric noble finds their toy running low on battery power and demands a refund from the hapless time traveler!
