Valheim building: support & wear

• Ground and rock give full supportA piece touching the terrain, or any solid object that is not a build piece (a boulder, a cliff), has its material’s full support.

• Support drops with distanceA piece resting on another takes that piece’s support, minus a share for every metre between their centres: the material’s vertical loss for a piece directly above, its horizontal loss for one beside, and in between for a diagonal. The piece keeps the best value any neighbour gives it, capped at its own material’s maximum.

• Bridging two supportsA piece resting on two supports on opposite sides of it (at least 100° apart seen from above) gets the average of the two, which is how beams spanning a gap hold more than either end alone.

• Below the minimum it breaksWhen support falls below the material’s minimum the piece takes its full health in damage and breaks, and the pieces it held recalculate.

The game has no names for its building materials; MaxDPS names each after the pieces that use it.

• Blue: full supportThe piece has its material’s full support, usually because it touches the ground.

• Green to yellow to redGreen is at least half the material’s full support; the colour slides through yellow and orange to red as support falls to the breaking point.

• Flashing blue in the Deep NorthA piece whose colour is below 60% of the way from red to green flashes blue there: heavy snow will damage it.

• Rain and water: 5% a minute149 of the 389 pieces (mostly wood) lose 5% of their health every minute while rained on without a roof over them or a shield generator’s dome, or while under water. It stops at half health, so rain alone never breaks anything.

• LavaIn the Ashlands, a piece standing on lava loses up to 70% of its health every 2 seconds, or up to 30% inside a shield generator’s dome. Falling ash does no damage to buildings in this version.

• Deep North snowSnow builds up on exposed pieces. Once it is heavy, any piece below 60% on the colour scale loses 0.5% of its health on every wear check. A roof or a shield generator’s dome keeps the snow off.
