Summary (Please read this!)

Originally posted by evilflora: !!! Please note that some Synthesis Targets will only spawn on Steel Path mission, sometimes on both or only on normal!

To clarify this, we will add this icon for steel path mission.

If the invading faction during an invasion wins the siege by getting to 100% occupation then the faction will change to (Occupying). For example, if the Corpus invaded the Rusalka (Sedna) node and won the invasion by getting the occupation percentage to 100% then the Corpus will take over the node and, instead of finding Grineer in the mission, you will then find Corpus in the mission.

This means any Grineer synthesis target that may have had a chance of spawning in that mission will no longer spawn there until it changes back to a regular Grineer mission after 24 hours of being occupied by the Corpus.

Remember, you MUST have a Synthesis Scanner in your gear wheel in order to have a chance of spawning a Synthesis Target (Codex Scanners will not spawn a Synthesis Target and cannot be used to scan one either). If you do not have at least one Synthesis Scanner in your gear wheel then the target will never spawn.

A note for the author, unsure if it's been covered in the comments.

During a 'post-invasion' event, (allowing different mobs to spawn from different factions) there is a chance that multiples of your synthesis target may spawn (Just happened to me with 3x 'Drahk Master' spawning at 'Shklovsky - Phobos').



When this happens even if you capture multiple targets you will only receive credit for one.

The information in this guide is constantly changing. Due to this, some information may be missing or incomplete.In addition, you MUST either be the host of the mission when it is started or load into the mission at the same time as the host in order for your Synthesis Target to have a chance of spawning. If the host also has a Synthesis Target then their target will spawn and not your own. If the host does not have a Synthesis Target but another player in the squad does and they load into the mission quicker than yourself then their Synthesis Target will spawn instead of your own. For this reason it is recommended to do these missions solo in order to guarantee a chance of your Synthesis Target spawning.You can also receive Cephalon Simaris Standing from Synthesis Targets spawned by other players in the party. To do this you must remain within affinity range (50 meters) to the Synthesis Target after all of the target points are scanned, and the target begins to de-materialize, until the standing is awarded. Although you do not have to scan any of the points yourself, you must have a Synthesis Scanner in your gear wheel to receive the standing.For more information about Synthesis, visit the Warframe Wiki page found here: Warframe Wiki - Synthesis. Synthesis Target missions listed below as "(Unconfirmed)" only mean the Synthesis Targets on said mission have only been confirmed by users in the comments. This, however, does not mean that the information is incorrect. It will be updated once one of the verified contributors to this guide have verified the results.Thank you to all of those who have contributed to this guide!
