I’m fairly new to Warframe, only MR 6 with a few weapons maxed (and sold) and just now making Rhino as my first new frame. I have been working through the star chart and completing quests as I got them.
In my adventures I have encountered some opportunities to grind for certain things. Reputations with the syndicates, rewards from Fortuna or the the happy family in Deimos, or that frame you can buy from Duviri wyrm kills etcetera. But how do I know what is worth going for?
I don’t necessarily want to rush to end game ASAP, but I also don’t want to spend time grinding for something that I would very quickly replace anyway
In my experience;
The best grinds are those that you’re either grinding multiple things at once. For example: Doing a mission that gives parts for something you want while also doing it as a Void Rift so you collect Relics (ideally also for Prime items you want). You would also, ideally, be leveling weapons simultaneously to these grinds to be grinding three things at once but as you go it gets harder and harder to have new weapons to grind.
There are a few grinds that are still very worthwhile even when they’re not multi-grinds. Getting to max rank with Fortuna is one of them. Efficient grinding of Focus for the Operator (once you get it, and the Zariman) is another.
