Deathsquito Lightning Tower

Deathsquito Lightning Tower

A storm-powered defense against Deathsquitos.

0.3.8 is a beta. Tested locally on Valheim 1.0.16 with BepInExPack 5.4.2351 and Jötunn 2.30.2. Multiplayer still needs testing with connected players.

Build and charge

Find Lightning Tower in the Hammer's Misc category. An Artisan Table is required.

| Material | Amount |

| --- | ---: |

| Thunder Stone | 5 |

| Copper | 15 |

| Black Metal | 15 |

| Crystal | 10 |

New towers start empty. Interact with a tower while carrying a Thunder Stone to restore all 30 charges. Thunderstorms replenish one charge every two seconds while the area is loaded.

Each lightning attack spends one charge and deals 50 lightning damage by default. Default range is 40 m with a two-second cooldown. The target list defaults to Deathsquitos and can include other creatures.

Ready towers coordinate their shots: for example, three towers with three reachable bugs can hit three different bugs. With one shared bug, the closest eligible tower gets the shot. With several bugs, assignment favors hitting as many different bugs as possible, then minimizes total distance.

Server compatibility

You can leave this mod installed when joining a server that does not use it, including a vanilla server. The tower stays inactive: it is hidden from the Hammer menu and spawn list, cannot be placed, and sends no tower attack or refill messages. It waits for the connection to finish before enabling tower features.

The tower works normally in single player and on servers that have the mod. Switching worlds or servers updates availability automatically; no restart or configuration change is needed. Use lt_status to check whether it is active.

Servers using Lightning Tower still require every player to install the same version, plus BepInEx and Jötunn. This protects clients from missing custom building assets. Other mods may have their own connection requirements.

Configuration

Launch the game once to generate BepInEx/config/valheim.lightningtower.cfg. Close the game before editing, then restart.

The plugin now uses the neutral ID valheim.lightningtower. When replacing an earlier development build, rename its Lightning Tower config to valheim.lightningtower.cfg before launching to preserve settings. Remove the old plugin DLL so only one copy is installed. Placed towers and their saved charge keys are unchanged. All multiplayer participants must use the new build.

Settings include attack range, capacity, damage, cooldown, target list, scan interval, line of sight, storm recharge rate, recipe, tower height, lightning width and jaggedness, charged halo size, attack volume, and hum range/volume. TowerHeightMeters defaults to 6 and measures the placement point to the highest branch; an additional 0.45 m of base extends into the ground at default scale. ChargedHumVolume defaults to 0.3 and ChargedHumRangeMeters to 3. Gameplay settings are synchronized from the host/server.

The [Crafting] settings are ThunderstoneCost = 5, CopperCost = 15, BlackMetalCost = 15, and CrystalCost = 10. Every enabled ingredient is recoverable. If all four are set to zero, the default recipe is used.

Example combat configuration:

[Combat]

TargetPrefabs = Deathsquito, Seeker, Gjall

LightningDamage = 50

BluntDamage = 0

SlashDamage = 0

PierceDamage = 0

FireDamage = 0

FrostDamage = 0

PoisonDamage = 0

SpiritDamage = 0

Use exact, case-sensitive creature prefab names. Spaces and duplicate entries are ignored; unknown names are logged and skipped. An empty list disables targeting. Players, dead and tamed creatures are always excluded. The one-to-one assignment also applies to mixed creature types.

Damage types add together, before the game's resistances, weaknesses and damage-over-time rules. Each accepts 0–10,000; zero disables that type. All types at zero prevents attacks and charge consumption. Existing LightningDamage values are preserved when updating.

For console testing, the prefab name is piece_lightningtower:
