This Dead Rails Wonder Weapons Update distills the 10/04 patch and same‑day hotfix into practical steps: how to find the new Evil Church, which Wonder Weapon to buy first, how Acid and the Corrosioneer class change your runs, what to do in the new biomes, and how to beat the reworked Nikola Tesla reliably.
What’s New
Wonder Weapons (Evil Church, Desert):
- Spear of Longinus — $250: Long reach; hits coat enemies in holy water.
- Holy Hand Grenade — $500: Delayed detonation; mini‑nuke AoE.
- Tesla Cannon — $750: Placeable defense; calls powerful lightning strike.
Acid System:
- Acid Barrel, Acid Bomb, new Corrosioneer class that starts with acid items.
- Cerebrus Blood (Acid + Unicorn Blood): puddles spawn friendly wolves.
New Biomes:
- Werewolf (Alpha Werewolf miniboss), Acid (acid rain & acid skeletons), Unicorn (rare).
New Challenges:
- Acquire the Spear of Longinus.
- Throw the Holy Hand Grenade.
Nikola Tesla Rework:
New animations and tweaked attack patterns.
10/04 Hotfix:
Correct wonder‑weapon pricing; Tesla Cannon now spawns properly in churches; Unicorn biome spawn rate reduced; Spear camera‑shake fixed.
Evil Church Route: How to Get All Wonder Weapons Fast
Where: Rare building spawn in the default Desert biome.
How it works: Each church offers one of the three items; pay the listed price to purchase.
Optimal buy order (cost vs. impact):
- Holy Hand Grenade ($500) — fastest town wipes, boss chunk damage, trivializes challenge #2.
- Tesla Cannon ($750) — safe boss DPS, lane control, excellent at Tesla Lab.
- Spear of Longinus ($250) — cheapest, great reach, enables challenge #1.
Money loop to fund purchases:
- Clear a town with basic gear → sell loot.
- If you spot Unicorn biome, capture/sell for a cash spike.
- Sweep deserts, hitting each Evil Church you find.
Wonder Weapons
Spear of Longinus ($250)
Role: Melee lane clearer with status utility (holy‑water coating).
Best use: Doorway duels in towns; poke from cover to avoid chip.
Tip: Two‑step rhythm — step in to strike, step out to reset aggro swing.
Holy Hand Grenade ($500)
Role: High‑radius, delayed mini‑nuke.
Best use: Pre‑place at chokepoints; throw and break line‑of‑sight, then re‑engage after detonation.
Boss play: Layer two throws on the boss path, kite him through the zone during fuse.
Tesla Cannon ($750)
Role: Placeable surgical burst; deletes priority targets.
Best use: Angle it across predictable paths (stairs, corridor middles, Tesla’s entry lane).
Cycle: Fire → manage adds with primary/Spear while it recharges → re‑aim for next pass.
Acid, Corrosioneer, and Cerebrus Blood
Corrosioneer Class
Starts with: Acid Barrel/Bomb.
Playstyle: Area denial; drop acid on bottlenecks to slow and shred waves.
Safety rule: Leave yourself a clean retreat lane; acid lingers and stacks mistakes.
Cerebrus Blood (Acid + Unicorn Blood)
Effect: Puddles spawn friendly wolves.
Use cases:
Boss distraction (buy time to set up the Tesla Cannon or grenade layers).
Town entry (wolves grab aggro while you flank).
New Biomes — What to Expect
Werewolf Biome:
- Packs run fast; Alpha Werewolf miniboss spawns.
- Keep grenades ready and fight in open lanes to avoid getting surrounded.
Acid Biome:
- Acid rain ticks; use cover and keep moving.
- Acid skeletons resist casual chip; rely on grenade/Tesla bursts.
Unicorn Biome (Rare):
- High‑value captures; quick cash infusions for church purchasing.
- Don’t linger — biomes rotate and you can over‑farm time.
Challenges (Fast Clears)
Acquire the Spear of Longinus:
- Visit any Evil Church that stocks it; buy for $250.
Throw the Holy Hand Grenade:
- Purchase for $500, throw once in a safe open area. Challenge completes on use.
Nikola Tesla — Reworked Fight Plan
Loadout: Tesla Cannon + Holy Hand Grenades + Spear (adds control).
Setup:
Pre‑aim Tesla Cannon at Tesla’s most common path into the arena.
Pre‑throw two grenades on that path to stack delayed damage.
Pull Tesla across your trap; fire Cannon as he enters the strike zone.
Control adds with Spear, backpedal to avoid new melee chains from his updated animations.
Repeat: Re‑angle Cannon if he leashes or pathing shifts.
Common mistakes to avoid:
Standing near grenade blast zones (fuse delay punishes impatience).
Misaligned Cannon angles (if it whiffs twice, pick up and reposition).
Acid self‑trap during kites (always maintain a clear lane).
Hotfix Notes That Change Your Run
Prices matter now: $250 Spear, $500 Grenade, $750 Tesla Cannon. Budget your early route accordingly.
Church spawn fix: Tesla Cannon reliably appears when rolled.
Unicorn biome rarity corrected: Expect fewer unicorn cash windfalls; plan a town clear as backup.
Spear camera‑shake fixed: Meleeing is smoother and more readable.
Recommended Loadouts
Town Clearing: Spear + 1–2 Holy Hand Grenades; cheap, fast, safe.
Boss Hunts (Tesla Lab): Tesla Cannon + 2–3 Grenades + Spear; add Cerebrus Blood for wolf distractions.
Biome Sweep/Church Hunt: Mobile class, basic rifle, Spear; buy as you go.
