After completing both level I proceeded to Rentar but Erika did not came(boon accepted and I asked her to activate the amulet, its in my journal)
Not only that, when I fought myself, still, nothing hopeful happened after doing this:
Press the Load Slime Compounds Button, then the Refocus Beams button, and finally the Begin Process button.
I am still doing an endless fight with Rentar. Please help
