Fun and work
The bolt, at its core, was a simple spell. It was a bunch of mana bundled together, shaped in an aerodynamical form, and infused with a simple intent consisting of direction and purpose.
It was its simple structure that allowed me to use it to chip away at the power of the otherwordly monsters by putting this world's mana against their anti-mana.
Yet, the bolt that I just shot out was different.
Rather than being guided with just the intent infused directly into the mana, it actually had a small array fitted at its core.
From a purely mechanical point of view, the one thing that the presence of this array-filled pebble did was add some mass to the otherwise purely magical attack.
But it wasn't those few grams of stone that would make a difference. It was the formation that I embedded into the pebble that made things interesting.
BOOM!
