Awesome, it sounds like you're making good progress! There are a few combinations of items you can use at this point.
You're on the right track with artefacts, both work as long as they are 'forged', but will have different results. Save before trying them.
'Swlrg' should work, as long as you have a viable artefact and ancra. You got that word from the ouija board, right? I'm hesitant to reveal the meaning of this text at the moment, I'm kind of waiting to see if anyone ends up translating all of that weird text. The full game will have additional clues for translating the text, but it's not something you need to do to beat the game.
What are you using as an Ancra? (rightmost stand?)
Thanks for the feedback, it's really helpful!
