I just finished the Botanist's Life for Me achievement hoping to get the Axe of the Luminary. But I get no axe reward lol! Anyone know how I get the weapon after I do the achievment?

I've tried checking my mail, armoire, and even the botanists guild and the calamity reclaimer lol... no idea where else to look

I want my weapon xD Probably missing something painfully obvious here tho
