AlienWarlord
Too bad you can’t use a spell to extract all the knowledge from a dwarves mind so you can learn to craft like a dwarf. If you’re not going to learn crafting from a dwarf, don’t limit yourself to just asking for something that holds infinity stones. Ask for multiple weapons and armor. You can always trade them materials, transport them somewhere via portal, or provide other incentives. And finally, warn him about Thanos coming there to have him craft an infinity gauntlet. Just tell him you have a friend who can see the future and they had a vision regarding the attack.
