Content Improvements
| # Designer's Comments We have been receiving a great deal of feedback regarding the performance of Transcendent Weapons used by firearm-specialized Descendants. We are aware of the same issues, and our internal gameplay data also confirms that, compared to Transcendent Weapons used by skill damage-focused Descendants, both the adoption rate and practical combat contribution are relatively lower.
Before making adjustments, we would like to first explain how we are analyzing the current situation and what direction we are preparing improvements in.
Transcendent Weapons used by skill damage-focused Descendants have high base amplification rates, and the way amplification is applied is also intuitive. Simply equipping the weapon immediately increases the damage of primary skills, so the value of the weapon can be felt relatively easily even before additional setups are completed.
On the other hand, Transcendent Weapons used by firearm-specialized Descendants are designed so that Transcendent effects are triggered or maintained in conjunction with shooting, since shooting itself is the primary source of damage. In this process, there are structures that require fulfilling specific conditions or repeating certain actions to maintain effects, and they were designed to achieve their intended performance only when modules, sub-abilities, and Descendant setups are sufficiently prepared.
However, aside from this design intent, we clearly recognize that the current performance of Transcendent Weapons used by firearm-specialized Descendants is not meeting expectations. Accordingly, we are preparing an overall buff for these weapons.
In addition to simple numerical adjustments, we are reviewing improvements that allow effects to be more reliably activated during actual combat flow, as well as reducing the conditions and operational burden required to maintain effects, thereby improving usability.
We will provide detailed information on the specific targets and adjustments as soon as preparations are complete. Furthermore, even after the changes are applied, we will continuously monitor actual gameplay data and feedback from Descendants to closely examine whether the intended level of performance is being achieved across various combat environments, including high-level content.
If we determine that further adjustments are needed, we will respond swiftly. |
