dice or the spell automatically fails. When you do, blood
flows from your body then crystallizes into a barbed
arrow, which launches at a creature of your choice
within range. Make a ranged spell attack against the
chosen creature. On a hit, roll the hit dice expended to
cast this spell, and the creature takes piercing damage
equal to the result.
Once lodged in the creature, the bloody arrow begins
to burrow toward its heart, rendering it vulnerable to
further attacks. At the start of the creature’s next turn,
it must make a Constitution saving throw. On a failure,
attacks against the creature score critical hits on a 19 or
20 on the attack roll.
At the start of each of the creature’s turns after that, it
must repeat the Constitution saving throw or the critical
hit range on attacks against the creature increases by 1
again. If the creature succeeds on three of these saving
throws (these successes do not need to be consecutive)

At the start of each of the target creature’s turns, it loses 1 temporary hit point granted by this spell. While the creature has any temporary hit points granted by this spell it moves with unnatural vigor, gaining a +2 bonus to all ability checks, attack rolls, and saving throws. Once it loses all remaining temporary hit points granted by this spell, the creature gains a level of exhaustion.

Creatures within 5 miles of you gain a level of exhaustion every 10 minutes they are directly exposed to the red rain. Each time a creature gains a level of exhaustion from this effect, it takes 2d10 necrotic damage and has its maximum hit points reduced by an equivalent amount until it is no longer exhausted.
While a creature has any levels of exhaustion caused by this spell, it automatically fails all saving throws against being poisoned or diseased. Beasts and plant creatures within the area of effect of this spell must succeed on a Wisdom saving throw or be frightened until they have spent 1 minute or longer outside the area of effect of this spell. Mundane plants within the area of effect of this spell wither and die after being exposed to the red rain for at least 10 minutes.
For each hour you maintain concentration on this spell, roll one of the hit dice expended in the casting of this spell then total the results at the conclusion of the spell. The total equals the number of days before beasts will willingly return to, and plants can begin to regrow in, the area that was affected by this spell.

If your sanguine poppet is ever reduced to 0 hp or more than a mile away, the spell ends immediately. As a bonus action on your turn, your sanguine poppet can walk or climb up to 30 feet, and you can see and hear through them until the start of your next turn.
As an action, you can cause the poppet to selfdestruct in an explosion of blood, ending this spell.
