Glad I was told about this before it finished. I guess I will have to throw my hat into the ring and give it a try or more specifically Aroth below will be the one trying as I don't have a death wish.
A good idea of what he is like would be combining Rincewind who can actually use magic but is all the worse for it and minus his genre sense with a human diplomat sent to a Dwarven Mountain home which is the result of a long succession game because his parents happened to like how Dwarven words sound so named him with them and the king thought that made him the best man for the job. He carries with him besides his generic wizard hat and robe a couple of gifts given to him by the dwarves before he set out by their request to "give it a try" by one of the dwarves (the dwarves have a substantial amount of beer and such riding on how long he survives with bets ranging from won't even be able to enter to him making it back because he is too stupid to die). The staff he carries was given too him with the cryptic remark of how he seemed to have been hit with it enough already so should return the favor to someone else and the tankard was given to him after being specially made to his size. Both where engraved by a crazy dwarf who before he left grabbed them and spent a few months locked in a craft shop before giving them back, Aroth tries not to look at the engravings as they make his head hurt.
Name: Aroth MÜmgozzanor

Class: Royal Diplomatical Mage Unit
Items: Royal Magical Staff being no more then 10' in length but no less then 9' in length titled "Eknar Sholil" made of Ironwood and is engraved with an image of Est ìfid, Legendary Tankard "Est ìfid" made of mermaid bones and menaced with Sea Serpent teeth with an engraving of Eknar Sholil
Spells: Summon Alcoholic Beverage, Heal, Acid Splash, Summon Alcoholic Beverage, Telepathy
Upon arriving at the tomb Aroth uses telepathy to locate if anyone friendly is in the place and locates Midna first because he has so much practice finding dwarves (the manager in the mountain home seemed to actively avoid him whenever he arrived so he had too polish this skill to an unhealthy amount just to find out what they wanted the traders to bring next time) and upon arriving at her locations notices the lack of beer so summons her a supply of it with Summon Alcoholic Beverage, then with the most pressing matters attended to Heals her.
