Best spell for magery training with 25 int?

[CaramelHorse]

I planned on using Mana Vampire from 75.5 magery until GM, but having only 25 mana means I can't cast it. I'm not sure invis is going to take me all the way to GM, so which spell should I use once I stop gaining skill from invis?

The stats aren’t too hard to change up and down so if you are doing Magery first then just bump your int to make it easier.

If you don’t want to adjust stats then it’s going to be pretty hard with only 25 mana but don’t forget to bless yourself for a boost there should bump you to upper 30s which opens up more spells. In which case definitely make use of dungeon exp boost and good luck
