Ruler of Ruination

Prestige 2 (Works Everywhere)

As you leave your mark on the world, all living things within the area begin to decay under your corrosive rule unless they swore their servitude to you. Those who aren't willing quickly learn it's within their best interest to serve you, if they wish to remain alive.

Ruler's Call - At the start of initiative, a wave of your authority runs through everyone within your aura. For every creature within your aura (including your domain) who is has your Servitude Blessing, you gain a +1 bonus to your armour class, saving throws, ability checks, attack rolls and damage bonus. When this ability is activated, creatures within your aura who don't currently have the blessing may choose to accept and gain the blessing, adding to your aforementioned benefits. 

Servitude Blessing - A creature who choses to stand by you and serve you can gain your blessing, which you grant to all willing creatures of your choice that you can see as an action. This blessing is symbolised by a fiery moth that lingers near their person. Whilst a creature has this blessing, they gain the ability to persist after regular creatures would fall. These creatures can not die as a result of failing death saves (for PCs) or being brought to 0 hit points (for NPCs). They also do not fall unconscious so long as they do not have an amount of failed death saves that'd normally consider them dead. You know the location of all creatures with this blessing at all times and, as an action, you can choose to see through the moth's senses that follows them. You can end this or switch to view another creature using your action again.

Prestige 4 (Works in native realm and realms where you have roots. Ex. Domain)

Your hatred for those who oppose you seeps into your rage and causes you to become more of a monster than you already are as you widdle them down to nothing. Causing their being to shatter and swiftly too their will.

Challenger Tether - You lay a corrupted bond between yourself and a creature of your choice you can see as a bonus action. This bond lasts until you dismiss it (no action required), the creature is on another plane of existence, or you choose another creature to tether. Any damage you or the tethered creature takes is dealt half as much to the other, using the same damage type. This damage does not trigger this abilities' effect.

Brittle - When you hit a creature, you can cause them lose half of their movement speed (rounded down) and take double damage from all sources until the start of your next turn. A creature with this effects has a shattered crown appear on their head, symbolising their inevitable fall.

Prestige 6 (Works in certain parts of the native realm)

At this stage, you gain the abilities to use your own enemies' strengths to your advantage. You show what happens when people step out of line and no ability is going to save them.

Domination - Choose a creature who has your Servitude Blessing as an action. That creature falls under Domination until you end it. A creature under Domination follows your direct commands in the fastest way possible. These commands can also include ones that would cause the creature to go into harms way.

Ruining Aura - Creatures within your aura who do not have your Servitude Blessing start to decay and corrode. Whenever you end your turn, all creatures within your aura gain a stack of Blister which are visible as boiling bumps on the creature's skin. Creature's who deal damage to a creature with Blister deal additional damage die equal to the amount of stacks they have. The additional damage is acid. This can be cured by 9th level Greater Restoration, Wish or they gain your Servitude Blessing. A creature killed whilst having at least one stack of Blister has their body melted into a pool of flesh as the acid destroys them.

Prestige 8 (Works in domain or with explicit DM approval)

Now you make those who defy you weak and defenceless, creating the ultimate safe haven for those who wish to live a life of security under your reign. Your domain always has your aura active for the purpose of all the abilities that revolve them.

Feeble - All items that are not in possession of you or those with your Servitude Blessing lose any and all of their magical properties whilst in your aura. Creatures' who don't have your blessing also can not benefit from any ability, spell or feature that grants them defensive attributes (reduction, resistance, immunity, bonus AC, etc) whilst in your aura.

Lingering Death - When a creature enters your aura for the first time, they gain a stack for Lingering Death. For every 6 seconds or every time they start their turn in your aura (whichever happens first), the number of Lingering Death stacks they have increases by one. This is represented by a tightened chain around the creature's neck, that progressively gets tighter the more stacks they have but is harmless. At any time, you may dismiss the chain as an action and if the creature has accumulated an amount of stacks equal to their charisma score, they die outright as you destroy their will to live. A creature who dies to this can only be brought back by Wish. These stacks are lost if the creature is outside your aura for 24 hours.
