Dragon's Spore Swarm

You summon a swarm of spores infused with the power of a dragon's breath. A cloud of shimmering, silver spores spreads out in a 20-foot-radius sphere centered on a point of your choice within range. The spores unfurl their delicate tendrils towards any living creature in the area.

Each creature in the area must make a Constitution saving throw. Creatures who fail take 5d6 poison damage and become poisoned for 1d4 rounds. Additionally, all creatures in the area that are not immune to being blinded become temporarily blinded for 1 round as the spores seep into their eyes.

When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
