Spells are Tools

Veer was making the magic circle for Arcane Shield as it was the safest spell in his arsenal. Even if it went off, he wouldn't be injured, not heavily at least.

For Arcane Shield, the magic circle needed a total of three Runes and they were relatively easy to carve. After making the Magic Circle, Veer muttered, "Arcane Shield."

Instantly, the magic circle shimmered in an ethereal glow as a translucent sphere appeared around him. He observed it while supplying it his mana.

'How does it even work?' Veer thought. 'This shield is just a sphere of Mana, so why doesn't it work when I try the same thing?'

After one minute, the shield dispersed in the atmosphere. Right after that, Veer took out his Spellblade and used it to channel his Mana to form a shield around him.

His mana leaked from him as he tried to control every single wisp of it. But it was clear that the farther it travelled, the worse his connection with it became.
