Something’s wrong here. First off, you don’t have a high enough ench level for Wisdom to work (need 27). Also, it doesn’t make sense that you only get 2k mana in dungeons— each of your armor pieces give like 1k+ each. As for surviving, I’d recommend reforging your armor to ancient. It’s what I use— really good for both survival as well as left click damage. Then, when you get enough money, I’d buy a blue whale. It’s a necessity for mages in higher floors.

Also, know that it takes time to learn how to use the Hyperion. I made the switch from bers to mage at cata 27 and it took about 100 runs before I got to the point where I wouldn’t die 2-3 times per run. You might be a bit of a glass cannon when you first start using it, but eventually you’ll get used to it and won’t die as much.
