A main-branch Hydra setup with a 7 SP upgrade budget
For a dragon summon whose published mechanics are concrete, start with Frostfire Hydra rather than trying to assemble every Breath and Egg interaction at once. The following setup uses the August 31, 2026 main-branch patch: range 5, damage 8, 24 HP, permanent duration, and 100 Poison resistance. Fire breath blinds for one turn and Ice breath freezes for one turn. These are the patch's base values before your bonuses; this is a planning sequence from those mechanics, not a recorded winning run.
- Establish the base summon. Buy Frostfire Hydra when you can afford its displayed spell cost while retaining a way to survive setup. Place it where its breath can reach enemies and where the wizard is not relying on the summon to prevent every incoming attack. The official notes do not state the base spell's SP cost, charge count or attack cooldown, so check those three fields before spending.
- Add Hydra Regrowth for 4 SP when the Hydra survives attacks but accumulates damage. The upgrade fully heals it each turn, replacing the old 16-point heal. Its loop is summon → survive incoming damage → heal on a later turn → keep attacking; it cannot bring a killed Hydra back or heal the wizard.
- Add Double Dragon for 3 SP when you have room for its symmetrically placed second Hydra. Inspect the second position as well as the first before casting. This is the expansion step, not a substitute for a safe first placement.
- Keep a separate defensive and damage answer. Fire and Ice give two damage types, but do not solve every resistance or protect the wizard automatically. Choose a currently affordable tool that answers the enemies in the next portal; a fixed extra spell is not part of this setup.
The two named upgrades cost 7 SP together, in addition to the base spell and any defense. If the first Hydra is already surviving comfortably, taking the 3 SP second summon before the 4 SP healing upgrade is a reasonable alternative; the order above prioritizes keeping one body alive. If you cannot afford both, buy the upgrade that fixes the failure you can actually see rather than saving for a nonfunctional complete package.
Orochi is a separate 9 SP alternative, not a required third purchase. The patch says it replaces the Hydra with Orochi when enough room is available; a crowded position is therefore the wrong place to depend on that replacement. The notes do not settle upgrade compatibility or publish a complete Orochi stat block, so this budget does not combine all three upgrades into an asserted final build.
The October 12 beta notes fix Flight of the Dragons failing to summon Frostfire Hydras. Keep that interaction outside this main-branch recipe: a beta fix is not proof it has reached main. Direct Hydra casting avoids making the setup depend on that reported failure. For an older Egg route instead, budget the patch's Incubation Exposure at 3 SP or Radiant Eggs at 3 SP; Scale Harvest costs 5 SP and now needs eight deaths, so it is not an immediate opening payoff.
Choose Breath or Eggs as the core engine
The sourced cases separate into two well-supported families. Dragon Breath cases scale a spell-casting engine through dragon spell density, charges or repeat casting, Ride Drake, and supporting effects, while Wyrm Egg cases build a summoning engine around egg production, minion scaling, egg spell-casting, and space. Both families appear in more than one pre-main player run. They are alternatives with different startup needs, not one shopping list that should be purchased together automatically.
Choose by the earliest coherent loop the current rewards can support. For Breath, ask whether another purchase increases usable casts, a confirmed dragon-linked payoff, or survival while casting; for Eggs, ask whether it improves reliable production, useful minion behavior, or room to hatch and act. A rare vault or shrine may radically change the answer in one seed. The official store supports open spell and equipment combinations, but it does not publish a dragon recipe or tier.
Build Dragon Breath around repeatable casting
Two independent pre-main sources describe a Dragon Breath direction. A July full-run video connects Dragon Breath to increased charges, a larger set of dragon spells, Ride Drake auto-casting, several drake types, multicast, and other supporting equipment, while a July Reddit report pairs Dragon Claw and Dragon Breath before adding inexpensive dragon spells. The common lesson is spell density plus repeated use and support, not any exact historical number. Every present charge count, cost, resistance, or trigger remains 待确认 until checked on current main.
Build Wyrm Eggs around production and space
The pre-main Japanese victory log starts by saving resources to acquire Wyrm Egg, then reports support from crafted equipment, Dragon Hunter's Sigil, Ride Drake with Flight of Dragons, spell-casting support, and Evasive Maneuvers for defense. The author reports a Mordred completion, but the claimed production loop and precise costs need a current check. This is a player-reported route with one run’s drops and decisions. Its strongest transferable lesson is to budget for startup and defense instead of buying only egg payoffs.
Keep Void and Storm as lower-evidence branches
The broader builds discussion contains player-reported Storm Drake and Dragon Mage ideas, and a commenter calls a Void Drake route especially strong. The official patch notes also describe a changed Void Mutations progression interaction, which proves that the mechanic was actively revised. These sources establish possible branches worth inspecting in the client. They do not supply a current systematic guide, replicated completion set, or basis for calling Void or Storm best.
Treat these branches as pivots when the run offers their confirmed tags and support. Write down the trigger, startup condition, defensive gap, and resistance coverage exactly as for Breath or Eggs, then compare how many existing pieces transfer. If the route depends on a historical tooltip or one commenter’s superlative, label that dependency 待确认. A promising branch is not a tier placement.
Apply the Aug. 31 boundary
The August 31 Patch Day notes directly changed several dragon-related systems. They altered Void Mutations, multiple Wyrm Egg upgrades, Frostfire Hydra, Flight of Dragons, and Dragon Roar behavior, which makes earlier costs and sequences unsafe to copy. The notes provide a dated official diff rather than a complete post-main build database. This guide therefore names affected mechanics but does not freeze patch-day values as permanent facts.
Before committing resources, open the current tooltip for the exact spell, upgrade, or item and verify its cost, trigger, tags, and recipient. Check whether repeated casts work as expected, whether egg support reaches the intended minions, and whether a defensive interaction still uses the same ordering. If the game client and an older run disagree, follow the client. Current complete tooltip data is 待确认 outside that direct check.
Separate lucky runs from reproducible guidance
Rare vault and shrine rewards can make one dragon run assemble unusually quickly. The first-time Reddit player explicitly describes the Dragon Breath success as lucky, so the case should teach opportunity recognition rather than promise the same opening. The egg reports likewise depend on particular crafts and support pieces. Record which part of a success came from the engine and which came from an exceptional reward.
