A DnD Tale: Curse of Stradh - Wintersplinters Coming To Town!

And he's bringing his naughty list

So the team take an hour to heal up and investigate the tree that bleeds blood. Hope reminisce about a vampire named Gulthias that was staked and from the stake sprouted a tree. The tree also reminds them of the staff the druids had in the winery. Imiral picks out the axe in the tree and even more blood flows out of the tree. Toby picks it up as the only one used to axes overall. Specially good as it is a magical axe. Now, I'm used to magical axe giving +1 so I might have put to much power since it's only magical and gives extra damage to trees so I might have to rectify it. So they basically feel the tree need to be cut down so Toby stays ready and starts to put the axe in position when they suddenly hear thunder strikes from the east, from Castle Ravenloft. It starts out as a black speck from where thunder strikes, but as it gets closer they notice a black horse with red mane which rides across the sky with a rider with pale skin, black hair and red armour. They quickly hide behind the tree.

The rider rides toward the stone circle and across the storm they here the sounds of a chant and the rider throws bolts of lightning within the circle and twelve figures raises from the ground, 6 berserkers and 6 druids. The druids stand in a circle in front of the statue and starts chanting while the  berserkers circle the druids watching the entrances to the circle. The group springs to action and charge at them. And the first stage of the battle goes ok. Katrina throws a fireball at 3 of the berserkers at first that make her grow a beard. Imiral and Hope uses their long range weapon while Toby and Cygnus forms a wall for the storming berserkers. The first berserker that reaches Cygnus heaves the axe and critical him, but with the help of Imiral and Hope the berserker is slain. Katrina uses Crown of Madness on another Berserker and gains command of him and set him upon his former friends. At the same time she gets even more health back... that was already full. Thanks.

Cygnus on the other hand has to heal himself with lay on hands since that one strike from the berserker bloodied him. During the battle the druids chant higher and higher. As the group push forward Katrina throws another fireball and with it the wild magic surges makes lightning flow from her body hitting one berserker and two druids... killing them all. They round up the rest of the berserkers and druids except one... that obviously is able to complete the ritual as the ground shakes and the statue beams of green light emitting from the chest. Another spell from Katrina turns her invisible and she runs toward the statue to pick up the gem. She climbs it and as the druid laughs like a maniac the roots around the statue begins go upward forming Wintersplinter (Katrina was able to stay on the outside). Imiral and Hope slays the druid while the other focus on the huge tree. Toby and Cygnus slashes with their weapons while Katrina throws of scorching rays on the tree. Which causes her wild magic surge to cast certain spells as an bonus action. Nice! Doesn't help that much when Wintersplinter uses two branches to hit her and Cygnus while the roots grab Toby and Hope. Cygnus tries to free Toby, but misses... twice. Hope on the other hand breaks free from her own and Imiral hits the tree while Katrina is able to throw of 5 scorching rays... that is 10d6 of damage (of course the draw back is that she now ages 6 years so she is 41 years old at the moment). Then Toby on his strength alone breaks free and with his last action swings his axe killing the tree and revealing the gem inside it as the green light shines out from it. Imiral picks it up and the session ends.
