Corvette

Adds an age-of-sail Corvette and its cannons to Valheim.

What you get

Piece	What it is
Corvette	Three-masted warship with its own hull model: 8 guns per broadside, 2 bow chasers, 2 stern chasers. Sails and handles like the Drakkar, with the Drakkar's storage.
Cannon	Placeable defense cannon, built and removed at a workbench. Wears out after 10000 shots and must then be repaired with the hammer.
Cannon cart	A cannon on a cart. Pull it like a normal cart; the gun points to the rear. It only fires while parked (not being pulled, not moving) with a player within 5 m.

All cannons aim and fire automatically at hostile creatures inside their arc, with target lead and ballistic drop compensation. Shells explode like the Staff of Fracturing (cluster blast + splinters). Cannons need no ammunition.

Building (Hammer, at a workbench)

Everything unlocks in the black-metal age (Plains): no Mistlands or Ashlands materials are needed.

Piece	Materials
Corvette	Fine wood 80, Iron nails 200, Black metal 40, Linen thread 40, Tar 20
Cannon	Iron 15, Black metal 10, Fine wood 10
Cannon cart	Iron 15, Black metal 10, Fine wood 10, Wood 30, Bronze nails 10

Admins can also spawn them: spawn VVLEE_Corvette, spawn VVLEE_Cannon, spawn VVLEE_CannonCart.

Notes

• Friendly-fire protection covers every friendly projectile in the game, including vanilla ballistas and catapults: they no longer hurt players, tamed creatures, ships, carts or your buildings. Monster attacks are unaffected.
• Everyone on a server (and the server itself) must have the mod installed.
• Models are generated procedurally by the mod; no asset bundles.
• Requires Jotunn.
