Well yeah, you've got a high power output with like no stabilization to it.

[They were dancing around it but Brad will just come out and say it. So much for not acting like a mage.

He will take the pen again and draw a similar design, but with a couple sets of double-lines here and there.]

Try that one. That should keep the output stable while still keeping the same strength. But how are you getting this to work at all? Are you using a mana stone as a power source or something?
