above level 20 boss power ups only drop on even levels removed mod ablative mines (was buggy, and too similar to ablative drones) flechettes get stuck in walls flechettes do no damage to mobs on hit flechettes do more damage over time, and have more ammo mod - flechettes pierce mobs mod - mutualism: each spore does 2x damage but they borrow 1% life from player
