This direction also proposes replacing Dynamo and Capacitor. A regular **Heatstep** transformation makes each deliberate Stride-powered pull scorch one visible ember into the floor wake. Only the three newest remain; the oldest visibly dims and goes out after a short shown interval. Forced motion, recoil and conveyor travel leave none. These are not battery charges: they show that the astronaut has kept the hot pursuit rhythm alive.

The second mapped trip in [Upgrade Choices](/Hold%20The%20Flood/Upgrade%20Choices) creates a fair test inside Storm Choir rather than a fourth fantasy. The astronaut carries the same Sensor, Projector, Dynamo, Fork, Arc and Capacitor through the same sealed pressure route. They already earned Thunderhead and chose Rebound Disc at the first Tune. At the sixth mark, one **40–75** hall band has broken for Echoing Arc while surviving bodies and the other band still contest Receiver Vault Approach. Neither treatment below is selected.

The current hybrid keeps the effects independent. An automatic disc follows its shown bank path. That Projector wave gives the locally clamped Dynamo at most one contribution; Fork feeds a rig-origin Arc action and Capacitor storage. Echoing Arc still starts from a target the astronaut can reach, and a distant rebound does not move the emitter.

The hint is already present: the Echoing Arc card shows connected bodies around the rig while the disc preview shows the fixed rib, pillars and terminal path. The astronaut experiments by moving until the nearest visible target gives the disc a useful line while another connected group remains in Arc reach. This is dangerous under Shutterback's fan and Siphon's line because the seven-space rig has no Barrier or Nozzle.

On a good sequence, lightning opens the nearby mass while the disc continues through a banked lane and the store rises toward Thunderhead. On a bad shot, a soft face or crowded segment ends the disc early, but the local Arc may still do useful work. Once the surviving pressure is cleared or separated, the astronaut captures the same seal strip and compares it with the hospital commissioning card.

This baseline has the strongest reliability and production case. It uses current links, local sensing, previews, heat, flight slots and the established Thunderhead discharge. Its weakness is experiential: the disc and Arc reward compatible positioning but can still feel like two attacks happening beside each other.

**Stormseed Disc** is a working label for one optional full-store mode, not a new part or upgrade card. It appears only when Rebound Disc, Echoing Arc and Thunderhead are already active. In the paused journal, the discharge preview offers either current Thunderhead at the rig or Stormseed's first currently shown disc/body contact. Choosing one mode excludes the other for that command and reveals no unseen target or route.

The rule change is narrow but real. A full Capacitor release still reaches Fork and divides **4 U** into the existing **2 U / 2 U** branches. Instead of producing Thunderhead's straight lance, Projector launches one Rebound Disc. The Arc branch uses one unit to reserve delivery and one unit for one normal Echoing Arc action; it gives up Thunderhead's three seed heads. Through a new delivery compatibility, that action attaches to the same parent flight instead of opening at the astronaut. The first valid body contacted by the disc becomes the Arc's initial body and origin; one base route and the two current Echoing branches begin there under their existing finite limits. The disc then continues with its remaining contact, distance, time and rebound allowance.

This does not turn Projector's physical output into a general signal port, let Dynamo hear remote impacts or give Arc a signal output. The contact only releases the electrical action already accepted for this manual wave. It happens once. The contact body is the disc contact and the Arc seed, not two Arc seeds; no rig-origin Arc or straight lance also occurs. The disc and every electrical route remain descendants of the same command, cannot recharge Dynamo, cannot refresh readiness and cannot create another discharge.

Activation keeps Thunderhead's current admission cost: a full **4 U** store, natural Projector and Arc readiness, the manual-ready hold and the complete **7 P** dispatch. The initial comparison also keeps Thunderhead's conservative heat row—Capacitor **+4 H**, Arc **+8 H** and Projector **+4 H**—rather than granting a discount for the different routes. Once launched, the disc keeps its normal flight slot and **1 P** reservation while the held Arc reserves **2 P** until contact or the disc ends. Later automatic fire must fit around that visible three-point hold. If the complete state will not fit, the command refuses before spending. After acceptance, obstruction, a lost group or a disc that reaches no body gives no refund; the Arc action dissipates when the disc ends.

When Echoing Arc joins Rebound Disc, the full-store preview can place a bright Arc-origin ring on the first body already shown on the bank path. The astronaut moves behind the receiver hall's shelter and pillars until the nearest visible target sits on the useful edge of a connected group, with a rebound line continuing beyond it. Holding that angle while Siphon or Shutterback threatens the approach is the setup.

A good press makes the combination unmistakable: one loaded disc reaches the chosen edge, lightning branches from that impact inside the remote group, and the same projectile keeps moving through its visible bank path. A bad press is equally clear: a nearer Presser crosses first, cover isolates the seed, or the disc misses every body. Lightning blooms from the wrong place or is lost, the store is empty, and neither local Arc nor lance rescues the command. The astronaut must survive the remaining hall and still earn the same quiet seal-strip inspection afterward.

Stormseed therefore buys one stronger causal surprise by sacrificing Thunderhead's safer local heads and straight lane. It also adds design and production work: a cross-branch link preview, loaded-disc state, first-contact marker, held Arc/readiness display, contact and fizzle feedback, sound and accessibility equivalents. Adoption would require the [Equipment Catalogue](/Hold%20The%20Flood/Equipment%20Catalogue) and [Mechanical Interfaces](/Hold%20The%20Flood/Mechanical%20Interfaces%20And%20Opening%20Quantities) to reconcile the contact-origin action, heat row, overlaps with ordinary flights, and future Fragment Wake or Long Arc compatibility. The cheaper baseline needs only clearer causal feedback between the existing disc impact and rig-centred Dynamo/Fork/Arc pulse; even that feedback has UI, effects and accessibility cost.

- Does Ricochet's smaller permanent footprint need another physical part or higher operating cost, or is its dependence on room geometry enough?

- Can automatic target selection and the first-contact preview give enough control without steering, remote sensing or a recipe list?

- Should an adopted Stormseed retain the conservative Thunderhead heat row, and how should its cross-effect overlap be shown without implying stacked kills?

- The rules are untested and all quantities remain proposals.
