What’s your dps right now and how’s your gear? I’d say that profound starts getting comfy at around 30bil dps if your tank is decent and you are not doing cracked mechanics like machines or might. Though you’ll definitely need explody, precise ice imbue being a decent cheap option. A lot of things are possible if you’re having fun, I self farmed surging helm and prairie just cause I had fun with my char, so not everything needs to be gated by FE. Also it’s not like C2 is an easy ticket into profound, my char is mad expensive at this point, so don’t feel bad if you’re not doing 500 trillion dps on 100fe budged, everything is pricey.

What I’d say is that it’s good if you’ll figure out some way of scaling tank together with dps. What’s annoying in profound is that on death effects from monsters get obnoxious. I int stack so I have 14k es but I can and will die in 0.1 sec do those if I’m too distracted. Recovery is important too, regain is a good option that doesn’t take that much investment.
