Full Barrier Domain

General Features of Domains

All the superior domains inherit the features of their previous ones. A Domain consists of many parts and all of them can be picked and chose to be used or be left unused. Out of these The Burnout and the Barrier (except in the case of the Incomplete Domain; Open Barrier still has a Barrier but is left intentionally open) cannot be left out as it is the cost of using the Domain. It is to be noted that except when you use a Focus you are always concentrating on maintaining the Domain, a broken concentration breaks the Domain Expansion. It is to be noted that you cannot normally cast spells when you use Domain Expansion except through the use of the Domain itself.

Sure-hit Effect

The Domains all have a Sure-hit effect, meaning all spells that are imbued within the Domain will hit regardless of any rolls or checks at the start of the round and when the domain is first cast. All creatures within the Domain are targeted simultaneously and individually by the Sure-hit effect, the Focus can extend this targeting to objects too. The attacks originate upon the target creature itself and therefore always hit. With Area Spells they are targeted/centered on the target creature. (It is possible for two creatures standing close by to be targeted by two AoE spells at the same time, in this case they can roll the save against the spell that was not centered on them) Lines and Cones always face away from the User of the Domain and are fired at pin-point on the targets.

There are, however, a few ways to avoid them: use a Legendary Resistance to negate the Sure-hit effect for a turn, use a Simple Domain or an Incomplete Domain to overwrite the Sure-hit effect, to be immune to the attack itself, to touch or hold on to the user of the Domain that one is in, or use spells such as counterspell and dispel magic as a reaction against the hit (this method only works on the first spell that is imbued).

It is to be also stated that the effects such as anti-magic field while active on the creatures within the Domain have no effect on the spells created by the Domain as its attack.

The user of the Domain is immune to the Sure-hit effects and the spells casted with it as are all those touching or in contact with the user.

Attack Enhancement

Domains are inherently your own space. Hence you always gain an advantage on all ability checks, saving throws and skill checks and a few other enhancements to your abilities and attacks. Damaging spells have their damage die increased in size by 1, if the spell has a condition then stack the duration of the condition additively or make the condition more severe, if it is neither then increase the intensity of its effect, this is up to your imagination and the DM's discretion.

Spell Imbuing

All Domains can be imbued with a spell or a magical effect that is automatically triggered when the round starts and when the domain is first laid out. The type of Barrier that is used is defining factor that decides how many spells or techniques can be imbued into a Barrier at a time. When the Domain is first expanded these spells can be chosen all at once if they are levelled spells then the slots are required slots are expended all at once. A spell can be chosen multiple times and if it is a levelled spell then the spell slot used to imbue it defines at what level it is imbued at (Note that the Attack Enhancement always comes prior to the Spell Imbuing so the spells are improved but that does not count towards the spell limit). The Barrier uses the spells in the order in which they are imbued, thus makes multiple, separate attacks if more than one spell is imbued. Only one spell that requires Concentration can be imbued into the Domain at a time. A maximum of three spells can be imbued into a domain at a time. Domains with a Focus can have four.

The following table helps determine the number of spell limit that a Barrier has.

Therefore, a cantrip counts as 1, a level 1 spell slot counts as 2, a level 2 spell slot counts as 3 and so on. A class or racial feature, magical in nature, is considered to be the same as a level 1 spell slot.

Barrier

The creation of a Barrier requires a verbal and somatic component. And, in the case of a Domain Expansion, requires concentration. A Barrier is regarded as a structure.

The Barrier is a necessity for making a Domain, if the Barrier shatters then the Domain simply ends. Closed Domains are often better in keeping creatures trapped within than preventing their entry. However, the DC and the condition can be switched around by the user, a higher level user may even make make it so that the barrier is impenetrable from the outside but shatters from the inside on a single touch. Domain Expansions are versatile and their many moving parts are supposed to be customized and played around by the player.

Barriers extend out to overlapping planes too such as the Ethereal plane, preventing escape via phasing out.

Burnout

It takes immense magical effort to create a Domain therefore, the caster loses their ability to cast spells once the create their Domain. And when a Domain Expansion ends, the user experiences a 'burnout'. A person cannot use a Domain Expansion while they are under the effects of the 'burnout'.

However, at higher levels (From level 17) you gain the ability to restore or heal your 'burnout' by using a healing spell/ability/or tool but reducing your intelligence score by 1. This feature called 'Burnout healing' can be used until you decrease your intelligence score below 9, if you do use the feature again the next burnout will also deal 8d6 psychic damage (10d6 at level 17 and 18) to you and you will be unable to use the feature again until your intelligence returns to 9 or above. And you cannot cast a Domain Expansion even if the ability scores are healed and 'burnout' removed until you finish a long rest.

The ability score damage remains lasts a long rest or until a healing spell is cast which has the effect of removing exhaustion on you.

A Domain Expansion can normally be cast only once per long rest until you reach level 17 and gain the feature to cast a Domain whenever you want except when suffering from a 'burnout'.

Full Barrier Domain

You learn to form a proper barrier. A Full Barrier Domain inherits all the features from an Incomplete Domain.

Activation

With an action you expand a domain enclosing all creatures within 25 feet of you. Creatures at the edge of your domain must attempt a dexterity saving throw against your spell save DC. On a failure you get to decide whether to enclose them in the domain or not, on a success it is up to the creature's discretion. The barrier goes around physical objects.

Spell imbuing

The barrier has the same effects as before (regarding cantrip spell effect strengthening), but now your spell limit increases to 2, which increases to 3 on level 14. Imbuing the spell in the domain uses a spell slot of the spell level, but when it triggers every round it does not consume a spell slot.

Duration

The domain lasts for 1 minute.

Barrier strength and breaking

The creatures caught within your domain can break out by breaking through the confines of the barrier by attempting a strength check vs your Spell Save DC + 10 or deal damage equal to your hitpoints at a certain point. Creatures that wish to attempt to enter the domain can break into the barrier by attempting a strength check vs your Spell Save DC or deal damage equal to half of your hitpoints at a certain point. Every time your barrier is broken its duration is decreased by 6 seconds. If the barrier breaks this way then you also take 5d6 psychic damage.

Barrier movement

You may move the domain along with its barrier (moving everyone inside as a result and possibly re-catching an escaping creature) at half your movement speed as a move action or an action. You may permit the entry and exit of creatures within your domain, doing so does not decrease its duration.

Burnout

When the domain ends you gain 1 level of exhaustion for 2d4 rounds and you may not use spells until this effect is over.
