Chapter 1: Moonshae Isles

There are two weapons. In case of a combat each weapon can be shoot once per combat round (constructs reload it full round). A character need to spend his turn to fire though - perhaps not the most effective weapon for lvl 15 PCs, but Mangonel at least has a good range

Weapon: Ballista
Ranged Weapon Attack: +6 to hit, range 120/480 ft., one target. Hit: 16 (3d10) piercing damage.

Weapon: Mangonel
Ranged Weapon Attack: +5 to hit, range 200/800 ft. (can't hit targets within 60 ft. of it), one target. Hit: 27 (5d10) bludgeoning damage.

Detect Thoughts
Casting Time: 1 action
Range: Self
Components: V, S, M (a copper piece)
Duration: Concentration, up to 1 minute

For the duration, you can read the thoughts of certain creatures. When you cast the spell and as your action on each turn until the spell ends, you can focus your mind on any one creature that you can see within 30 feet of you. If the creature you choose has an Intelligence of 3 or lower or doesn’t speak any language, the creature is unaffected.

You initially learn the surface thoughts of the creature—what is most on its mind in that moment. As an action, you can either shift your attention to another creature’s thoughts or attempt to probe deeper into the same creature’s mind. If you probe deeper, the target must make a Wisdom saving throw. If it fails, you gain insight into its reasoning (if any), its emotional state, and something that loom s large in its mind (such as something it worries over, loves, or hates). If it succeeds, the spell ends. Either way, the target knows that you are probing into its mind, and unless you shift your attention to another creature’s thoughts, the creature can use its action on its turn to make an Intelligence check contested by your Intelligence check; if it succeeds, the spell ends.

Questions verbally directed at the target creature naturally shape the course of its thoughts, so this spell is particularly effective as part of an interrogation.

You can also use this spell to detect the presence of thinking creatures you can’t see. When you cast the spell or as your action during the duration, you can search for thoughts within 30 feet of you. The spell can penetrate barriers, but 2 feet of rock, 2 inches of any metal other than lead, or a thin sheet of lead blocks you. You can’t detect a creature with an Intelligence of 3 or lower or one that doesn’t speak any language.

Once you detect the presence of a creature in this way, you can read its thoughts for the rest of the duration as described above, even if you can’t see it, but it must still be within range.

Starting at 1st level, you can form a telepathic connection between your mind and the mind of another. As a bonus action, choose one creature you can see within 30 feet of you. You and the chosen creature can speak telepathically with each other while the two of you are within a number of miles of each other equal to your Charisma modifier (minimum of 1 mile). To understand each other, you each must speak mentally in a language the other knows.

The telepathic connection lasts for a number of minutes equal to your sorcerer level. It ends early if you are incapacitated or die or if you use this ability to form a connection with a different creature.

Right creature: seems good humans, they should know something about the evil one. Just need to force them talk
Left creature: humans avoided question about vessel content! They are hiding the demon in there!

Gust

Casting Time: 1 action
Range: 30 feet
Components: V, S
Duration: Instantaneous
You seize the air and compel it to create one of the following effects at a point you can see within range:
One Medium or smaller creature that you choose must succeed on a Strength saving throw or be pushed up to 5 feet away from you.
You create a small blast of air capable of moving one object that is neither held nor carried and that weighs no more than 5 pounds. The object is pushed up to 10 feet away from you. It isn't pushed with enough force to cause damage.
You create a harmless sensory effect using air, such as causing leaves to rustle, wind to slam shutters closed, or your clothing to ripple in a breeze.

abjuration
Casting Time: 1 action
Range: Self
Target: Self
Components: V S M (Ashes from a burned leaf of mistletoe and a sprig of spruce)
Duration: Up to 1 hour
Classes: Druid, Ranger
A veil of shadows and silence radiates from you, masking you and your companions from detection. For the duration, each creature you choose within 30 feet of you (including you) has a +10 bonus to Dexterity (Stealth) checks and can’t be tracked except by magical means. A creature that receives this bonus leaves behind no tracks or other traces of its passage.

Casting Time: 1 action
Range: 60 feet
Components: V, S, M (a bit of fleece)
Duration: Concentration, up to 10 minutes

You create the image of an object, a creature, or some other visible phenomenon that is no larger than a 15-foot cube. The image appears at a spot within range and lasts for the duration. The image is purely visual; it isn’t accompanied by sound, smell, or other sensory effects.

You can use your action to cause the image to move to any spot within range. As the image changes location, you can alter its appearance so that its movements appear natural for the image. For example, if you create an image of a creature and move it, you can alter the image so that it appears to be walking.

Physical interaction with the image reveals it to be an illusion, because things can pass through it. A creature that uses its action to examine the image can determine that it is an illusion with a successful Intelligence (Investigation) check against your spell save DC. If a creature discerns the illusion for what it is, the creature can see through the image.

We have come to seek information and guidance in our hunt of a vile necromancer in league with a powerful demon. They have been killing many creatures in the seas and other isles. If there is any information you can share with us we would be grateful.

Casting Time: 1 action
Range: 500 feet
Components: V, S
Duration: Concentration, up to 10 minutes

You create linked teleportation portals that remain open for the duration. Choose two points on the ground that you can see, one point within 10 feet of you and one point within 500 feet of you. A circular portal, 10 feet in diameter, opens over each point. If the portal would open in the space occupied by a creature, the spell fails, and the casting is lost.

The portals are two-dimensional glowing rings filled with mist, hovering inches from the ground and perpendicular to it at the points you choose. A ring is visible only from one side (your choice), which is the side that functions as a portal.

Any creature or object entering the portal exits from the other portal as if the two were adjacent to each other; passing through a portal from the nonportal side has no effect. The mist that fills each portal is opaque and blocks vision through it. On your turn, you can rotate the rings as a bonus action so that the active side faces in a different direction.

You pull wisps of shadow material from the Shadowfell to create a nonliving object of vegetable matter within range: soft goods, rope, wood, or something similar. You can also use this spell to create mineral objects such as stone, crystal, or metal. The object created must be no larger than a 5-foot cube, and the object must be of a form and material that you have seen before.

The duration depends on the object’s material. If the object is composed of multiple materials, use the shortest duration.

Material Duration
Vegetable matter 1 day
Stone, crystal 12 hours
Precious metals 1 hour
Gems 10 minutes
Adamantine, Mithral 1 minute
Using any material created by this spell as another spell’s material component causes that spell to fail.

5' cubic = 60*60*60=216000 inch cubic

Making cage walls of 30 poles= 50 walls

That should be big enough to hold them, top, bottom, walls

You send a short message of twenty-five words or less to a creature with which you are familiar. The creature hears the message in its mind, recognizes you as the sender if it knows you, and can answer in a like manner immediately. The spell enables creatures with Intelligence scores of at least 1 to understand the meaning of your message.

You can send the message across any distance and even to other planes of existence, but if the target is on a different plane than you, there is a 5 percent chance that the message doesn't arrive.
