What else can Ezreal make?

This is something that I've been wondering even before the lore rewrite/rework. Ezreal's gauntlet seems to be capable of a number of different things, but there are two particular abilities it has that seem to be a bit more prominent than others: one is teleportation, and the other is creating a magical bow that fires energy arrows.

The Gauntlet of Ne'Zuk, in-lore, is stated to be primarily told of in legends as allowing its wearer to traverse vast spaces in the blink of an eye, but none of its other qualities are ever really talked about. This leaves me wondering: can the gauntlet make things OTHER than the energy bow? In the right hands, could it be used to summon energy swords, spears, or even shields? What are the limits of its creation ability, and is it even possible for Ezreal to utilize them?
