Bullet lines

is a defensive system assist  that allows the player's targets to see the trajectory of the bullets that are being aimed at them. as it allows a player with high agility (AGI) and enough courage to evade more than 50% of an assault rifle's continuously fired bullets.

ou can see a colored line whenever you’re being attacked by a ranged attack by the person you can see.
As a reaction you can use movement to weave around the projectile.
Works on blue dragon breath or any ranged spell that forms a line.
