After unlocking the recipe, you should be able to craft the Reinforced Climbing boots by supplying the required materials to the regular Armorer’s Bench, which are the Epic Light Gauntlets / Boots ( from the Exile Epics feat, crafted in the Improved Armorer’s Bench ), the Twine and the Star Metal Bars.
It is indeed confusing if it requires the epic light boots and gloves because this can’t be crafted on the improved bench, only in regular bench and the requirements shows light boots and gloves as if regular light gear. Edit: I meant to say the reinforced climbing gear isn’t crafted on improved bench but the epic light gear is. Sorry lol
It is helpful to have both benches next to each other I just bounce back and forth to see what works. How ever don’t put a recycling bench next to them. Great way to make scrap oops.
