You should get Shatter instead of Firestorm since you already have 20 earth magic and only a little fire magic. Also, Lehudib's Crystal Spear. You also want Regeneration, which you should keep on whenever you are below max HP. Passage of Golubria will be helpful for escaping from enemies, and you'll eventually want to upgrade to Controlled Blink. Controlled Blink will take a lot of Translocations to get, but it's absolutely worth it since it gives you an almost instant escape from any dangerous situation. Aura of Abjuration is also nice to have in extended for fighting summoners (demonspawn summoners, panlords, hell lords, greater mummies, serpents of hell), and fairly cheap to pick up for a mage character like you. And you need Apportation to help grab runes.
You need more Spellcasting, in the 15-20 range or more, not least because you need it in order to memorize these additional spells, and you also need more MP. I would amnesia Stone Arrow and Mephitic Cloud. Also you need more Fighting for the HP.
If possible you should wear an Amulet of Magic Regeneration.
Do Tomb last, with Controlled Blink and Shatter. On Tomb:1, you can Shatter near the entrance to Tomb, to open up the large central structure. Greater mummies will come out and start tormenting you, but you can Shatter or Iron Shot/Crystal Spear them, and retreat back out of Tomb to rest if it starts getting too hot. Fight near the entrance to stay safe. Once Tomb:1 is clear, there are several stairs down to Tomb:2. The stairs near the middle of Tomb:1 are the most dangerous ones. The central stairs are the ones characters who don't have Shatter are forced to take. You should instead take the stairs near the corners of Tomb:1. On Tomb:2, first you should read Magic Mapping to locate an up-stairs if one isn't already in view. Then, you need to get to the up-stairs, by walking or using Controlled Blink if necessary. Now while standing on the up-stairs you can fight the monsters using Shatter, and escape up the up-stairs when your HP gets low. Repeat this until all the monsters on Tomb:2 are dead. Now when you go down to Tomb:3, immediately read Magic Mapping. Get to the up-stairs back to Tomb:2 as fast as possible using Controlled Blink. Again, fight the monsters on Tomb:3 using Shatter while standing on the stairs. If your health gets too low, go back to Tomb:2 and repeat. I think you will be strong enough to kill everything on Tomb:3, but if you decide it's too dangerous, you can try to ninja the rune using Controlled Blink and Apportation to quickly get to it and then get back to the up-stairs.
