You utter the magic words 'cwician ysl'
A stream of green light erupts from your hands and wraps itself around Sloth.
Your fingertips are surrounded with swirling ENERGY as you cast the spell.
The air is filled with pure energy and crackles with power.
Unseen BURSTS of magic are absorbed into the spell!
You watch with self-pride as your spark birth hits Sloth.

...
At least got decent amount of sparks...
