Usage
Passive
- [Passive, True] Spacetime Manipulation
- [Passive, Toggle] Thought Acceleration
- [Passive, In-Slot] Detect Weakness - While this skill is in slot, entities you hit will progress the production of your Lethal Dose.
Actives
- [Active, In-Slot] Bloody Bite - The user strikes at an enemy, spending some of their MP to inject them with their Poison. If the Detect Weakness is at 30% of less, this move only deals Physical and Spiritual Damage. (Halved by Abnormal Condition Resistance, reduced by 25% with Nullification). If Detect Weakness is at 50%, it infects them with Magicule Poisoning. If Detect Weakness is at 80%, it becomes Lethal Poison. If it is at 100%, it becomes Cursed Poison.
- [Active, Hold] Poison Refinement - While Held, this move will slowly drain the user's MP and begin producing 2.5% (5% on mastery) of the progress for your Lethal Dose a second.
- [Active, Press] Death World - This can only be used when your Lethal Dose is at 100%. The user pulls all targets into their Death World Dimension. All entities inside of the Death World without [Samael,Lord of deadly Poison] are given Cursed Poison 3.
Any target pulled it which is not both a Spiritual Lifeform and wields an Ultimate Skill is instantly killed, otherwise, it deals 25 Spiritual Damage + 5% of the user's Nihility as 1/2 of it is used to deal Void Damage per second.
- [Active, In-Slot] Nihilistic Poison - The user begins to release their Nihility much faster, draining it into their palm, this makes it so the Nihility is drained by 3.5% on hit (2% when mastered) to gain a bonus 5% on the target's Lethal Dose. When the Lethal Dose is at 100%, they will take 200 Spiritual Damage + 10% of the user's Nihility as Void Damage.
- [Active, In-Slot] Nihility Supply (Requires Mastery) - While the user can generate Nihility passively in slot as they develop their Lethal Dose, they gain 1 Nihility for every Lethal Dose % they gain. Their Nihility can scale up to 10,000 points before the user begins to take 50 Void Damage a second until it is decreased below 10,000. The user can have a maximum of 25,000 Nihility.
Nihility Generation is 20 Spatial Damage to 1 Nihility.
- [Active, Press] Multidimensional Barrier - Like the extra Skill Multilayer Barrier
