First off wanted to thank everyone who chimed in on my last post I feel like I'm no longer stumbling around in the dark.
But I've started to grind towards wisp prime while progressing my start chart using this wiki to see what relics I need and where to get them, but I've been having bad luck
I got one of my friends to help me earlier during a void fissure mission but still no luck opening getting the blueprints
I'm sitting on a radiant relic that has the blueprint for wisp but I'm holding off on opening it in case there's something I can do to further increase my shot on getting the gold tier wisp blueprint
Yup, the pre-made messages are just convenient way to let the seller know which item you want without having to type it out yourself. You should get an invite from them to their dojo and then the trade commences. Just click on any of the boxes on your side of the trade and select platinum, type in the amount and verify that the item they are trading you is the one you want (I've never had someone try to scam me but better safe than sorry). Do watch out for your daily trade limit, your mastery rank is how many trades you can do per day.
Does not matter, so long as a message beings with a /w it will always become a whisper. From then on, it will get it's own separate channel tab (you can close it by right clicking on it).
