So..I skip my forge key step. Got it.
I get the amber from my opponent forging keys. Got it.
Does this mean they don't forge a key? Do they forge a key AND I get six amber?
If they have 13 amber...do they attempt to forge, I get six, they don't get a key...they try again...I get six...now they have 1 amber remaining and I have twelve and they have no key?
The action makes sense. I just got all this amber now I kill the artifact and give my opponent one turn to react and try to stop me or or get it back.
