About NorthernGemcraft

From Thunderstore

Put your Deep North Ancient Coins and gemstones to use: set gems into armor and weapons at the crafting station and polish them for small, capped bonuses. No new buildings or items.

Northern Gemcraft

Sitting on a pile of Ancient Coins and gemstones you can only sell? Put them to work.

The Deep North showers you with Ancient Coins and four kinds of gemstone: Grimvarn, Solryth, Veydris and Draumyx. Vanilla only lets you sell them. Northern Gemcraft lets you set those gems into your best armor and weapons at a fully upgraded black forge or Galdr table, and polish them with Ancient Coins. Each gem gives a small benefit and a smaller drawback. No new buildings, no new items: just a meaningful use for your Deep North loot that keeps the game's balance.

Requirements

  • Valheim 1.0.20 or newer, with BepInExPack for Valheim.
  • Multiplayer: install on the server and on every player (see Multiplayer).
  • To use it in game:
  • a fully upgraded black forge (level 6, all extensions) or Galdr table (level 5, all

extensions),

  • Ashlands-tier gear or better made at that station (Flametal, Ashlands weapons, Ashlands

mage gear and staffs, and all Deep North gear),

  • Deep North gemstones and Ancient Coins.

Getting started

  1. Find Ancient Coins and gemstones in the Deep North.
  2. Discover enhancing: open the crafting menu of a fully upgraded black forge or Galdr table

while you carry (or have picked up before) an Ancient Coin and a gemstone. You get a "Discovered: Enhancing" message for each gem you know. This happens once per character.

  1. Open the ENHANCE tab next to CRAFT and UPGRADE at that station. It lists your eligible gear

made at that station, one row per action:

  • Set a gem (gems you have discovered): one gemstone plus Ancient Coins. The item gets the

gem at grade I. Rows show even before you have the gem or coins; like vanilla recipes, they are greyed out and the missing cost blinks red until you can afford them.

  • Polish: more of the same gem plus more Ancient Coins, up to grade III. Each grade adds the

gem's effects again.

  • Remove: Ancient Coins. The gem is destroyed (configurable).
  1. Select a row, check the cost on the right, and press the button. The station-level icon shows

the level enhancing needs.

Gems

Each gem has a benefit and a smaller drawback. Values are per grade; grade III gives three times as much.

| Gem | On armor | On a weapon (while in hand) | | --- | --- | --- | | Grimvarn (green) | +1% max health, -1% stamina regen | +10% durability, +1% stamina per attack | | Solryth (orange) | +2% stamina regen, -0.5% max health | -3% stamina per attack, -5% durability | | Veydris (purple) | +2% eitr regen, -1% stamina regen | -3% eitr per cast, -5% durability | | Draumyx (black) | -1% physical damage taken, -0.5% movement speed | 1% life steal, -2% health regen |

  • Armor (helmet, chest, legs, cape, shield) counts while worn, and all worn pieces add up.
  • Weapons count while in your hands. Durability changes the item itself.
  • Caps: a gem's main benefit (listed first) is capped for your whole kit: max health +10%,

stamina regen +15%, eitr regen +15%, physical damage taken -8%. When a cap cuts a benefit, that gem's drawback is cut by the same share.

  • Life steal heals you for a share of the damage you deal, up to the enemy's remaining health.

Hitting players or tamed creatures heals nothing.

Costs

| Step | Gems | Ancient Coins | | --- | --- | --- | | Set (grade I) | 1 | 20 | | Polish to II | +1 of the same gem | 60 | | Polish to III | +2 of the same gem | 150 | | Remove | - | 30 |

One piece at grade III takes 4 gems and 230 Ancient Coins.

What you see in game

  • Item tooltips show the gem and grade, with its effects: benefits in green, drawbacks in red.
  • Tooltips also list your totals from all gems together, with each cap and whether it is

reached.

  • Weapons show their enhanced stamina and eitr cost in parentheses next to the normal value, e.g.

Use eitr: 20 (17.4).

  • The movement speed total includes gem effects.

Good to know

  • Gems belong to the individual item, not to the item type.
  • Saved with the item: gems last through logouts, and stay on the item in chests, on the

ground, and in your tombstone when you die. Equip the item again and its gem works again.

  • Upgrading an enhanced item keeps its gem.
  • Mistlands and earlier gear, and other stations, can't take gems (by default).
  • Nothing changes for players who never enhance anything.

Configuration

The config file is created the first time you start the game with the mod installed:

BepInEx/config/com.jonasd.valheim.northerngemcraft.cfg
  • Mod manager (r2modman, Thunderstore Mod Manager, Gale): open your profile's config editor

and pick com.jonasd.valheim.northerngemcraft.

  • By hand: the BepInEx folder is in your Valheim folder, or in your mod manager profile

folder. Open the file with any text editor.

  • Dedicated server: edit the same file in the server's BepInEx/config folder.

The file is plain text: a [Section] heading, then one Name = value per line. Lines starting with # are explanations. Restart the game (or server) after editing it.

Costs (1 - Costs)

| Setting | Default | What it does | | --- | --- | --- | | MaxGrade | 3 | Highest grade (1 = no polishing) | | SetCoins, PolishToIICoins, PolishToIIICoins, RemoveCoins | 20, 60, 150, 30 | Ancient Coins per step | | SetGems, PolishToIIGems, PolishToIIIGems | 1, 1, 2 | Gems per step | | RemoveReturnsGem | false | true = removing gives one gem back |

Gem effects (2 - Gem effects)

Each gem has a list for armor and one for weapons, as Effect:value-per-grade, comma separated. The first entry is the main benefit. Change the numbers, swap effects between gems, or give a gem completely different effects.
