Ultimate Gley Demonic Modification builds changed on October 22 when The First Descendant patch 1.4.6 adjusted True Aim, explosions and the unique weapon’s fixed fire rate. If an October 15 setup feels different, it probably is: the weapon now fires at 157 rounds per minute, its explosion has a lower base coefficient and holding True Aim increases explosion damage more strongly.
The best starting point for Ultimate Gley Demonic Modification is a Skill Power-oriented setup with enough HP to survive the module’s True Aim health cost. A publicly shared area-clearing build supplies a real set of supporting modules, while Nexon’s official patch notes tell us which damage values are current. Below you’ll find both, along with the rotation and the trade-offs worth considering before investing more catalysts.
Ultimate Gley Demonic Modification build modules
Equip Demonic Modification as the Transcendent Module. For a usable Ultimate Gley Demonic Modification starting loadout, the following modules appear in a real post-1.4.5 area-clearing build on TFD Hub. It was last updated October 15, so its individual stats are not proof of the absolute best loadout after October 22. The module names and overall damage/HP priorities remain useful to test on the new version.
| Module | Role in the setup |
|---|---|
| Demonic Modification | Transcendent module changing Skill 4’s unique weapon |
| Focus on Dimension | Dimension-oriented Skill Power |
| Non-Attribute Amplification | Non-Attribute damage emphasis |
| Non-Attribute Syncytium | Additional Non-Attribute support |
| Life Resonance | HP to help absorb the True Aim health cost |
| Spear and Shield | Defensive and damage support |
| Skill Expansion, Bio Expansion | More area coverage |
| Skill Extension | Skill duration |
| Walk a Tightrope | Conditional damage at a health-risk trade-off |
The community setup also uses a Materialized Phase Reactor and an Ancestors Module called Thirster’s Resolution. That is a concrete example, not a demand to reproduce every socket or catalyst before the build works. For Ultimate Gley Demonic Modification, start with the skill-damage pieces and enough HP to finish attacks; only then experiment with risky conditional bonuses such as Walk a Tightrope.
Patch 1.4.6 damage values and fire rate
Nexon’s October 22 patch sets the following current Ultimate Gley Demonic Modification values. The explosion’s base damage decreased, but its increase from True Aim grew substantially. That combination is why comparing only the base explosion number can give the wrong impression of the patch.
| Stat | 1.4.5 | 1.4.6 current |
|---|---|---|
| Fixed unique-weapon fire rate | 120 r/min | 157 r/min |
| Base explosion damage | Skill Power × 8,942.0% | Skill Power × 6,259.4% |
| Explosion True Aim increase | 44.2% per 0.1s | 92.1% per 0.1s |
The tooltip now calls the mechanic Damage Increase on True Aim, instead of Focus Additional Damage. Nexon separated the normal-damage and explosion-damage descriptions and removed a Fire Rate 50% line that wasn’t actually applied. Patch 1.4.6 also fixed additional damage incorrectly failing to affect Demonic Modification’s explosion. Older videos may therefore show the previous coefficients alongside damage that was affected by the pre-fix explosion bug.
How to play Ultimate Gley Demonic Modification
Begin with a safe position and enough HP for the attack. True Aim consumes health over time, so decide where to fire before committing to a longer aim. When enemies gather closely, release the modified unique-weapon attack where its explosion can catch more than one target. Then move or recover as needed before repeating. This is the basic Ultimate Gley Demonic Modification area-clearing loop.
Against a boss, timing becomes more important. Holding True Aim longer can improve the relevant damage but also spends more health and leaves you committed to the shot. Test shorter and longer windows against the same target on patch 1.4.6, and compare both damage and your remaining HP. Nexon hasn’t published a single best aim duration for every reactor, module configuration and enemy.
Don’t mistake the 157 r/min fixed rate for a regular firearm speed bonus you can freely scale without limit. Equally, avoid designing the Ultimate Gley Demonic Modification setup around the old 50% Fire Rate tooltip, because Nexon explicitly says that figure was never applied. The current effects listed on your equipped skill are the ones that matter.
What reactor and stats should you prioritise?
The published area build uses a Materialized Phase Reactor, matching the Non-Attribute and Dimension direction of its module selection. That offers a starting point for Ultimate Gley Demonic Modification, but the precise best reactor substats depend on the rest of your equipped gear. Check the Skill Power and damage changes in your live character information before replacing a reactor that already performs well.
HP has a direct gameplay purpose here. Spending more health than you can safely afford can interrupt your damage rotation, so a weaker-looking but durable setup may clear a full run more reliably. The Gley October rework guide covers changes to Thirst, Blood and Iron, Explosive Life and other options that might influence your equipment decisions.
Demonic Modification compared with Explosive Life
The two modules support different skills and playstyles. Demonic Modification rewards managing True Aim and its explosion. Explosive Life was redesigned towards Skill Power and skill critical hits in 1.4.5, and 1.4.6 increased its maximum Life Spheres from 10 to 20. Choose the module that matches the combat loop you want, rather than assuming a single damage chart ranks them across every activity.
For Ultimate Gley Demonic Modification, Onslaught and Bounty Operations are places to try its area damage against groups. Stage 5 still requires barricades to prevent Tyrants reaching the Energy Concentration Point and has a Colossus after six waves. Our Onslaught Stage 5 guide explains those mechanics, while the Monster Hunter rifle guide covers a separate large-enemy weapon option.
Cradle of Evolution requires more than enemy damage: Vulgus Shells can’t be destroyed with ordinary skill attacks, and the laser room has its own objective. See the Cradle walkthrough before relying on explosions for every room. The daily weapon boost guide also helps if you’re farming equipment alongside character improvements.
Common build mistakes after October 22
The main Ultimate Gley Demonic Modification mistakes are using the old 8,942.0% explosion value, expecting the removed 50% Fire Rate line to work, and chasing the longest True Aim without considering HP. The 1.4.6 values are 6,259.4% base explosion damage, 92.1% added explosion damage per 0.1s of True Aim and a fixed 157 r/min firing rate.
Look at actual clears as well as individual damage numbers. A setup that regularly finishes its attacks, controls health loss and hits grouped enemies can be more useful than a fragile version that only looks impressive against a stationary test target. The Freyna and Enzo rework articles provide other current options for a squad, but they don’t change the way Ultimate Gley Demonic Modification uses True Aim.
