Currently just three projectile modifier cards and two perks, but I intend to add more eventually.

Cards:
Avoidance causes projectiles to attempt to avoid the terrain. It's a much stronger effect than Avoiding Arc.
Corrective Thrust causes projectiles to adjust their trajectory closer to the direction they were fired.
Furious Buildup gathers strength and enhances the projectile.

Perks:
Peppy Pauper gives enemies a chance to drop a healing item INSTEAD of gold. Health pickups are a heavily modified version of the ones by VileGoo ( https://modworkshop.net/mod/26132 ).
Segmentation gives you segmented health regeneration, at the cost of max HP.

You can disable the perks individually with the config file, if desired, as well as tweak them for balance.
