well, it's a free refresh for stage dodging just like blueprint and a free shop node every floor and bosky. the shop is the strongest node in IS5, especially if you've got the rare collectibles upgrade in a run. it can get you every busted relic not covered by lamp, and save you wish nodes by getting you the relics you might've taken from lamp regardless, like the 8 ingot king's relics.
you're also fishing for visage of crowned fates to run king's+sarkaz king's, which spamming shops helps you find, and it gives you a huge amount of flexibility in when to rob. it's free plans every time you enter a shop too, and free ingots which gives you more aspd and more flexibility for buying.
you can play runs normally and refresh whenever you've got an abundance of ingots, need a free plan, need a stage dodged, want to rob, right before heading into lost and found to pick up qui'lon's relic, etc. etc.
it makes you stupidly busted
