So, does Devargo Barvasi walk around looking like Wolverine all the time, or are the spikes on his gloves retractable? I imagine it might technically be possible to grasp other items with the spiked gauntlets on, but gods help you if you forget and try to scratch an itch!
Devargo's willing to suffer for fashion... ;)
More seriously I imagine he only has the spiked gauntlets equipped when he's handling business or feels the need to look appropriately intimidating. He is, after all, a man who is willing to let large spiders crawl all over him for the sake of his vanity title as the King of Spiders, so clearly appearances are very important to him when he is interacting with others. But if he's lounging around in private or engaged in activies where the spiked gauntlets would impede him, I imagine he takes them off.
