Destiny 2’s A Rising Chorus Act One questline tasks players with finding Radiolaria Samples as part of its 20th quest step, leading players back to Nessus for another round of collecting resources. Luckily for guardians, though, their locations are easy to find.

Step 20 of Destiny 2‘s seasonal questline for Echoes may feel more like a fetch quest, but it’s a somewhat quick and painless step if you know where to find Radiolaria Sample sites. This step borrows the proximity sensor mechanic from previous weeks but with much easier targets.
