v2.01.1 Change List

Gameplay

[p align="start"]Eidolon planet development

[p align="start"]The Eidolon get more out of the worlds they take, and colonizing one no longer runs into conflict with shroud limitations.

[p align="start"]Safeguard Device: The Eidolon armor failsafe was firing as often as corruption allowed. It now has a 60 second passive cooldown, reset when the device triggers.

[p align="start"]Advent Unity Abilities

[p align="start"]Intense Gravity Field (Buff)

[p align="start"]Focus Conversion

[p align="start"]The Advent research line now has one source of truth. The per-asset research modifiers are the whole rate, and the flat conversion baseline in the Advent player definition has been removed. Rates you have already researched are rebuilt when an older save loads, so nothing is lost in progress.

v2.01.0 Change List

Gameplay

[p align="start"]Iskazhar Epitaph (Buff)

[p align="start"]The Eidolon Starbase has grown more powerful and precise, with one new upgrade and one improved upgrade.

[p align="start"]The Dimensional Shifter teleportation can now be targeted to a specific location in its destination gravity well. However, with precision comes a need for information, and the ability now requires vision over the target to activate. Fortunate then, that the Eidolon can observe a destination unseen...

[p align="start"]The Phase Destablizer has been added to the Starbase as a new researchable item. This device will damage the hull and drain the antimatter of enemy forces attempting to jump away from it. This cannot kill a target... But it can leave them weakened and perilously close to death.

[p align="start"]Sythren Onslaught (Buff)

[p align="start"]This unit is intended to act as the Eidolon early anti-capital unit, as well as an anti-heavy cruiser option. In order to better fulfil this, its missiles have been improved, with greater range, pierce and superior straight line movement stats. Additionally, the missiles it fires are now tougher, allowing the unit to resist Point Defense a little more reliably.

[p align="start"]Corruption Targeting (Buff)

[p align="start"]Propagate Mode and Vile Presence will no longer spread Planetary Corruption to allied planets. See how magnanimous the Eidolon are, to withhold their sinister gifts from their future thralls allies.

[p align="start"]Corruption Mitigation (Buff)

[p align="start"]Shortly after the arrival of the Eidolon Vanguard the mysterious Phase Jump Inhibitor used by all factions began to demonstrate a new function - seemingly capable of purging corruption from a planet and even calming the Shroud. Researchers from all factions have shown great interest in this technology now that the threat posed by the Eidolon has been made clear.

[p align="start"]Granular Corruption Mitigation Research. Existing mitigation techs have been split into entire tech lines, to better allow the other factions to gradually fight back against the planetary maluses imposed by the Eidolons.

[p align="start"]Vespa Corvette (Nerf)

[p align="start"]The Vespa Corvette was added to provide the Advent an early high-pierce option to deal with capital ships and structures prior to the Exoria Illuminator at Tier 3. In this role, it has excelled - a little too well, in fact. In order to bring it back in line with its intended role, we have reduced its damage output and survivability, while moving it to Tier 2 to more closely align with the early pierce focused units of other factions.

[p align="start"]Focus Conversion (Nerf)

[p align="start"]Focus Conversion is a mechanic we added to the Advent in order to reflect the Psionic nature of their commercial economy prior to their invasion of Trader Space, as well as to assist with their early game economic woes. In order to better perform that task while maintain both lore consistency and balance, we have adjusted the first two techs in this line to be Focus to Credit only, and to be available at Tier 1 and 2 for easier access. The Advent retain the ability to convert Focus to Metal and Crystal much later in the game at Tier 5, but at reduced rates. We will continue to monitor the impacts of this new function on Advent gameplay.

[p align="start"]Other balance
