Sgrios sighed and rubbed his face, drqgging his claws through the fur on his ears. "Spells are all about intent. You dont even need to make any sound while casting them, its just easier for most to keep their intent in mind if they are talking about it. But it isnt required. For example, my specific branch of magic, called Storm Singing, is usually cast via humming or singing wordless notes" he explained
Sgrios huffed softly "i never said you had to." He rumbled, his tail twitching a little. "But that doesn't matter if you dont have a Focus. I dont need one, because i am my own Focus. Humans however need one. If i remember right most humans use wands or staffs, though some use other things like amulets or weapons
"They likely still have a focus, probably some sort of jewlery. Humans can cast magic without focus, but is much more difficult" he said before tilting his head "casting magic without a focus is like trying to empty a lake with your hands. You can do it, but it would be easier with a bucket.
