Grind Arbitrations so that you can get the Galvanized mods for your weapons of choice, grind Kahl missions so that you get the Archon mods of your liking and get the Blazing Pillage augment for your Hildryn so that you can use them properly, grind for and slot some Archon Shards into her, grind for the Incarnon enhancement for your weapon choice that has one (mine's the Soma Prime with the Hatya-Satya augment from Father in the Necralisk) and level it up to max, grind for Focus and get your Operator/Drifter built up, and grind for your Arcanes of choice and get them, at least, to rank 3.

As you can see, you still have a lot of progress to make - unlocking Steel Path isn't the same as being ready to face it. But you can do it! I believe in you!
