Death's Head Shroom

You point to a target within 90 feet and cause the earth to sprout a Death's Head Fungus, which sprouts fibrous spider-like legs made from moss and charge the target.

Make a ranged magic attack. On a hit, the fungus leaps onto the creature, latches to them with tiny teeth, and begins to siphon the life from them, causing 1d10 necrotic damage every round for 1 minute.

The only way to remove the fungus is for the target to be struck by fire damage.
