Version and source limits
This skill is registered in the reference release. The installed version and server configuration have not yet been matched. The acquisition review below checks reference-build conditions separately. Other usage details describe the cited wiki revision, not verified server behavior.
The upstream article is incomplete; missing effects or unlock conditions are not assumed.
Reviewed reference-build evolution route: Sloth → Belphegor. Separate the skill’s stored reserve, your maximum Magicules, and the bed-progress counter.
Prepare Sloth’s reserve
Fully master your own permanent Sloth. Its storedMagicule tag must hold at least 25,000 stored Magicules by default. Current player MP is not this reserve.
Build bed progress
The default is 12,000 recorded ticks standing still on a bed. The condition also requires you to be on a bed when checked. Sleeping through a night is not the predicate inspected here.
Meet the player thresholds
Reference defaults: at least 1,000 recorded mob kills and 1,000,000 maximum Magicules. These are a player statistic and a capacity gate, not held items or current MP.
Before evolving: the selected helper removes Sloth after successful learning. Gamerules, skill configuration, and the bed tracker must permit the route. Active server settings and successful evolution remain unverified.
Bed progress: ticks, standing, and configuration
The configured bed minutes are multiplied by 60 × 20. At the default of 10 minutes this is 12,000 ticks, nominally ten minutes at 20 ticks per second. No wall-clock timer or reliable live completion time has been verified.
The predicate checks a server player, horizontal movement squared no greater than 0.0001, and sampled bounding-box overlap with a block tagged BEDS. It then requires designer_bed_still_ticks to meet the threshold. Ordinary sleeping state is not checked.
The inspected tick helper increments the counter while this bed predicate is true. Leaving the bed does not reset the counter in that helper, but you must be on a bed when eligibility is evaluated. Other reset and persistence paths remain unverified.
The shared tracker uses Designer’s separate slothBedMinutesRequired setting, default 60, to enable tracking. A nonpositive value resets the counter to zero. That setting does not replace Belphegor’s default ten-minute threshold. The handler calls the tracker on its server-player tick path; effective runtime cadence remains untested.
Evolution gates and exact counters
The selected route requires nightmare_ultimates, auto_evolve, and Belphegor’s enableUltimateEvolution. The two gamerules default to false; the skill setting defaults to true. Review the gamerules. Already owning Belphegor blocks another evolution.
The reserve predicate reads Sloth’s skill-instance tag; the kill predicate reads Stats.MOB_KILLS. Both accept the configured minimum. The shared helper checks maximum Magicules with a 0.000001 tolerance; this does not prove the complete learning pipeline never charges resources.
The helper rejects predecessor tags trnightmare_directive_ego and AkashicStarOrderImprint, records predecessor mastery, and forgets Sloth after successful learning. Keeping both skills is not promised. Alternative routes and surrounding event ordering remain unverified.
Belphegor’s default mastery target is 15,000 from ultMasteryConfig.masterySinUlt, replacing the source’s 5,000 value. Acquisition evidence · Reviewed release. Usage effects remain source-described, not a complete effect audit.
Usage
Passive
- [Passive, True] Lord of Lethargy:
- Whenever the user sleeps in a bed, they fully restore a large sum of magicules, and any amount that would bring them above 100% is stored as temp MP.
- [Passive, In-Slot] Phantasmal Style:
- Applies an effect that deals 2.5% of the target's spiritual HP (5 when mastered) to the user's attacks. The user also has a chance of applying a level of Drowsiness to the target, (15% Chance, 30 when mastered), up to level 8. The user increases the Spiritual Damage they do by 50 for every level of Drowsiness the target has.
Active
- [Active, Press] Fallen Catastrophe:
- The user can attacks a target, and instantly kills any target that doesn't check 2/3 of the conditions. If 2/3 conditions are met, it gives them drowsiness 4, if 3/3 are met, it gives them 3 instead.
- Spiritual Attack Resistance or Nullification.
- Greater than 30% of the user's EP.
- Has an ultimate skill.
- The user can attacks a target, and instantly kills any target that doesn't check 2/3 of the conditions. If 2/3 conditions are met, it gives them drowsiness 4, if 3/3 are met, it gives them 3 instead.
- [Active, Press] Fallen Thanatos:
- The target the user is looking at is given Drowsiness every 7 seconds. The target dies once the level of Drowsiness hits 10..
- [Active, Press]Fallen Strike:
- The user's attacks deal 2.5% of the target's spiritual health damage (5% when mastered). This stacks with Phantasmal Style. Any target that doesn't possess an Ultimate Skill will be instantly killed upon their Spriitual HP reaching 30% of lower.
- [Active, Hold] True Sleep:
- The user dozes into a sleeping state while it is held down, the player is unable to move, attack, or activate other abilities. Regen 100 (+10% of target’s max with Mastery) HP and Spiritual HP per sec and increases the players MP, and AP Regen by 100X. If MP is at max, it fills up a temporary MP storage at the same rate. If there is enough MP in the temporary storage (1000 x Y = X [Y = Number of Allies. X = Cost]), crouching will restore 2000 MP, 2000 AP, 100HP and 20 Spiritual HP to all allies within a 30x30 radius. Any nearby enemy instead has their SpiritualHP reduced by 20 and their MP and AP reduced by 100 every second per level of Drowsiness they have. When looking at no target and crouching, show the quantity of MP stored.
