Spell modifiers that change how projectiles interact with solid terrain.
A modifier that causes a projectile to try and avoid hitting terrain, veering off in a free direction most in line with its current trajectory. The modifier has a limited amount of strength, so projectiles that are too fast or shot perpendicular enough to terrain will still hit it, as well as enclosed spaces or dead ends.
Has some synergy with the Homing modifier/perk, as projectiles will a have better chance to reach what they're tracking instead of crashing into terrain.
