Songs - Rituals created by blending three or more Melodies together. They are capable of affecting planets at the larger end, yet pay the price for their power by inflicting horrendous wounds on the Choir using then if used in combat against void ships/stations or entire armies.
Dirge for the Innocent - Allows you to lay the uneasy dead of an entire world to rest, denying those souls to Chaos. (As long as they hadn't already pledged themselves to it.)
Bound To The Stars - Enables your Choirs to act as akin to an average Navigator. This enables you to traverse Unstable Warp Routes without suffering Warp Damage unless the routes utilized are tumultuous.
A Web Of Song - Enables a Choir to forward messages up to five systems away as long as there is another Choir stationed there.
A Glint of Genius - Can assign up to 40 Choirs to Research, adding +0.01 Research per Action Spent per Choir.
Turn Their Eyes Away - Enables a Choir to turn all attention from them and those they designate within a ~200km radius.
Break Your Chains - This Song amplifies and enhances feelings and sentiments of dissatisfaction, agression, rebellion, and dissent within all who hear it, growing stronger the more people hear and act on the feelings roused, while being focused and guided against the foes of the Hymnals instead of following the mind of the crowds.
Diverting Power - Enables a Choir to divert hostile Warp Energies around a bubble centered on themselves to another place. The size of the bubble can be improved by Psytech, Arcane Sigils, Sacrifice, and Power.
The Devouring Mechadendrite - Each Choir assigned to this Song grants an extra 2.5% Progress to [General] Actions, Research Excluded In All Matters, up to 50%.
Unto Works Generational - Reduces Action Cost of all General Actions by 33%, but requires 50 Choirs to operate. If said Choirs are removed, the reduced Actions are re-applied. In that case, Action Cost Reductions, if Unto Works Generational is sung again, are calculated upon the new re-applied Costs, instead of overall costs. This only affects Full Actions.
Paths Without Treason - Requires 10 Choirs. Neutralizes Chaos Corruption within Machines over months, instead of years. (Depends on level of Chaos Corruption.)
Heartbeat of Industry - Reduces Action Cost of Military Actions by 25%, but requires 50 Choirs to operate. If said Choirs are removed, the reduced Actions are re-applied. In that case, Action Cost Reductions, if Heartbeat of Industry is sung again, are calculated upon the new re-applied Costs, instead of overall costs. This only affects Full Actions.
Hippity Hoppity - Requires 100 Choirs to operate. Find 1 [One] Dark Age of Technology Ruin the Turn after. Loot varies starkly, and no important finds are guaranteed. But finds are.
Hiss of the Steam Valves - Unlocks a 5 DP Ship Equipment that costs a Choir. Choirs assigned to Sing Hiss of the Steam Valves in your Manufactories imprint a [Minor] resistance to Warp Corruption into every item constructed within.
See No Evil, Speak No Evil, Hear No Evil, Do No Evil - Requires 500 Choirs to operate fully. Upgrades [A Hand to Hold the Candle, A Hand to Guide the Sword, A Mouth to Sing the Hymns, Two Feet to March against the Dark, and Eyes to See the Star Child's Light] to [My Soul Has Seen The Glory Of The Coming Of Our Star...]. Singing at less than 100% Choir Requirements transfers an equivalent of 0.2% of the trait per Choir assigned. The trait will apply to all Non-Faithful half effectiveness.
Foretold Luminous Paths Seen - When Sung with 50 Choirs, this Song enables you to gain insights into schemes and plans created via Prophetic Sorcery and Scrying, as well as Runic Casting and Fate Weaving. Does not work on Computational-Based fate-telling.
Dutiful Spirits - This Song imbues a minor passive resistance in all your Machine-Spirits against Chaos, scaling with the number of Choirs assigned to it. Machines without Machine-Spirits obtain half the effect.
Class Is In Session - Each Choir assigned to this Song grants an extra 2.5% Progress to [Psykana] Actions, up to 150%.
Placebo - Requires 100 Choirs per Sub-Sector. Noticeably slows down transmissions of Warp-Borne Pathogens.
Promethean Gaze - Allows Choirs to call down vast pillars of Stellar Wrath upon their enemies, engulfing them in promethean fire until naught but cinders remain to feed on their ashes.
Soul's Shield - Soul's Shield allows Choirs to fully deflect up to Medium Chaos Sorceries within a Small Area centered around a point of their chosing within 20km of their position.
