You use it to dye your tames by dying the dust and putting in your tames inventory and tap “remote use item”. If you’re early game, go to your mortar and pestle. Then tap on your amber and click “crush”, which will give you 2 podent dust per 1 amber. If you’re not so early game you can use an industrial grinder. Basically just do the same thing you do with the mortar and pestle but instead you tap “grind” and it gives you 6 podent dust per 1 amber.
