Blood Tree

Aberrant Ground. The blood tree is rooted in an area of aberrant ground. Any creature that ends its turn within 5 feet of the tree must succeed on a DC 15 Wisdom saving throw or be affected by confusion for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Aura of Madness. Creatures within 30 feet of the blood tree that can see it must succeed on a DC 15 Wisdom saving throw or be affected by the tree's aura of madness. An affected creature is affected by short-term madness for 1 minute.

Blood Drain. The blood tree drains blood from creatures within 5 feet of it. A creature must succeed on a DC 15 Constitution saving throw or take 14 (4d6) necrotic damage and have its hit point maximum reduced by an amount equal to the necrotic damage taken. This reduction to the creature's hit point maximum lasts until the creature finishes a long rest. The creature dies if this effect reduces its hit point maximum to 0.

Multiattack. The blood tree makes two slam attacks.

Slam. Melee Weapon Attack: +7 to hit, reach 10 ft., one target. Hit: 21 (3d10 + 6) bludgeoning damage.

Blood Burst (Recharge 5-6). The blood tree causes the blood of creatures within 30 feet of it to explode. Creatures within the area must succeed on a DC 15 Constitution saving throw or take 14 (4d6) necrotic damage and be stunned until the end of their next turn.
