The First Descendant has a wide variety of materials that you need to find to craft new characters and weapons. One of the rarer materials is the Anode Iron Particles which are needed to craft multiple weapons and Descendants.
How to get ANODE ION PARTICLES into the First Descendant (QUICK GUIDE)
Here's how to get Anode Iron Particles in The First Descendant and the best way to farm them.
Anode Iron Particles drop from Elite enemies in Hagios. One of the quickest missions to farm this material is the Broadband Fleet Beacon in Forward Base. The mission takes place in an area where you must kill enemies, destroy the generator, and stay in the circle with orbital bombardments.
This mission features three Elite enemies that can drop the Anode Iron Particles. The first one carries the bomb for the generator, and the other two spawn during the circle phase of the mission. Kill them both for a chance to get the Anode Iron Particles.
