As the title says I started playing warframe a couple days ago and I’ve loved every moment of it.As of this moment I’m mastery rank 4 with rhino,mag,frost and Excalibur warframes built.I have a decent number of rare mods and as well as the staple bronze ones.For missions I have mostly stuck to and focused on finishing the star chart and as of this moment I’m right now on Jupiter.My only fear is that I’m going to be stuck at the same power level to the point where going forward into the game it’s going to be very hard to progress.

What do I need to do to get stronger?.Also are there any specific items or mods that I will need.Sorry if this is a noob question still learning a lot about the game.Any advice is well appreciated.
