Point is we need to but a leash on this concept. Lightspeed is the ultimate power that can be obtained as far as I see things. I'm not saying we need to kick it to the curb but if we don't we need to set some restrictions.
To have lightspeed:
-You must be using a spell, no passive effect can generate lightspeed
-The primary aspect of the magic or magic item must be light
-While traveling at lightspeed you are incapable of attacking, catching, grabbing, blocking, anything. Only moving.
-You cannot change direction while moving at lightspeed, you can stop then change directions and start again but not mid travel.
Regarding Lightspeed Projectiles: No.
If it doesn't follow those guidelines I say
- Spoiler:
Regarding the inevitable "Okay if not lightspeed what is the fastest we are permitted?" As a member of the development team I am currently working on App Rubrics, which will be set universal grading criteria for app checking. The question will be addressed once I get that finished.
