The chances of that happening are astronomically low of course, but it doesn't hurt to be prepared. I wouldn't spend any more resources (Seeds), but reaching 100 Reds has a good chance of getting you LMB on the weapon.
I've gotten to the point where I actually have a dupe for both the SSR weapon and the eidolon after I MLBed them. I know the benefits of having dupe MLB weapons (it's possible given my current pace), but I don't main dark (but this is less of a concern to me given I could just pull core dark hime over time). I'm concerned about dupe MLB SSR eidolons though, already have a list full of SSR eidolons, would I get any use out of an extra? If no, are there future updates that allow me to convert the useless dupe into something else?
