Mage/Dark Wizard Help Fire-defense Solo-warring Mage

Low budget, has to be under 32le

Trying to be able to solo territory's with medium-low defenses
I've been recommended to go spell based with peaceful rest and king of hearts as a secondary. However I'm not sure if I should build spell steal or just plain old mana regen, as well how much my spells need to cost with a certain intel in order to sustain a cycle.

I've been given this build. https://wynnbuilder.github.io/#4_0lS0dL0u50Ty0aK0K00TN0OM0A4000021120s1g00001006CO
For 1 cost meteors and snakes, but lower mana regen / steal. I am not sure if I really need to get them both down to 1-costs because it means my defense/fire damage won't be as high when I have to put so much into intel.

Is there another variation with lower intel but higher mana regen / steal so I can get more defense / fire dmg?

Feel free to dm me on discord too at Sur#9802

 

Any input would be highly appreciated :)

 

Here's one of my old concepts that seems to fit your description:

Here's a build that I actually used, not sure how it would go warring, but has more dmg and less def
