and they glow a lot so i didnt miss my loot detector at all

A not very convenient way in the heat of battle is to use https://warframe.fandom.com/wiki/Detect_Vulnerability on Helios. But you could do it once for science and then you know

Also Banshees Sonar skill

Join a clan if you have not already, they usually have researched a bunch of good weapon/frame blueprints you can buy and build if you want some diversity

Yeah it’s in settings

I suggest you dont sell anything for ducats until you know what you want to buy and how much you need. Then try to get by with only selling duplicates at first, this way you can build your arsenal at the same time for MR experience. And if you want to take it a step further, check the prices for the pieces before you sell them. You might have gotten a vaulted piece from someone elses relic that you are not likely to get ahold of again any time soon

Excaliber Umbra has better stats and umbra polarities, and since you have the mods I guess you have the frame (was a while since I did that, but I think they come together?) Also if you don’t have it already, Healing Return or Life Strike on your melee could help some. And what the others said
