Fungal material coalesces into a mushroom cap shield. This magic shield lasts until the spell ends. It counts as both a shield and a simple weapon with which you are proficient. It grants +2 AC, deals 2d8 necrotic damage on a hit, and has the thrown property (range 40/120).   In addition, when a creature misses you with a melee attack, you can use your reaction to release a cloud of spores over it. The creature must make a Constitution saving throw. On a failed save, it takes 2d12 poison damage and is poisoned until the start of your next turn. On a successful save the creature takes half as much damage and is not poisoned.   If you drop the shield or throw it, it dissipates at the end of the turn. Thereafter, while the spell persists, you can use a bonus action to make the shield reappear in your hand.
