Terraheim is both an overhaul for Valheim's armor system with the goal of making each armor set viable all the way to the end of the game and a weapon expansion that fills the gaps in the games base roster.
Nine new weapons and tools have been added with the goal of filling in the gaps in each tier.
These weapons are as follows: Bronze Battleaxe, Iron Knife, Forstasca (Silver Axe), Folcbrand (Silver Greatsword), Silver Kresja (Atgeir), Blackmetal Spear, Blackmetal Axehammer(Greataxe), and the much coveted Blackmetal Pickaxe.
You can view damage values, moveset information, and recipes here in the Weapons tab.
If you only want the new weapons, you can delete the Terraheim.dll file to disable the armor changes.
Each piece of armor has been given its own unique effect and each armor set its own set bonus while also allowing armor to be 'uptiered,' which increases all of the piece's stats to be usable in the next tier of gameplay. If you only want the armor changes, you can delete the TerraheimItems.dll file to disable the armor changes.
Each armor set has been divided into three classes:
Berserkr's have a focus on dodging, axe damage, two handed weapon damage and stamina management.
Bowmen focus on dealing damage via, well bows, as well as daggers and spears. They focus on ammo consumption, backstab bonus, and sneaking. They have the worst armor rating in game.
Shieldbrothers are adept at blocking and have increased health. They can effectively deal damage with all melee weapons, but they are slower than the other classes. They have the highest armor rating in game.
You can view the full values for each set across every tier here!
As you progress through the game, you will be able to uptier armor. Essentially leveling the armor up to utilize the new materials you come across. When you do so, the armor set's armor rating increases, and every one of its bonuses becomes more effective. For example, you can uptier the Bronze Helmet to become an Iron-Reinforced Bronze Helmet by combining a Bronze Helmet, some Iron, and some Deer Hide at the forge. By doing this, it's armor has increased from 15 to 19, and it's bonus(+5% Melee Damage) increases to +7% Melee Damage. Uptiering means that you won't have chests full of out-dated equipment as you can continually have the armor set keep pace with your progression! Note that to uptier padded armor, you have to use the Artisan Table asides from the forge or workbench.
Currently two utility items have been added, the Aescfell Belt and the Stánbrysan Belt. These items increase your damage dealt to trees and ores, respectively.
Terraheim is highly customizable as the effectiveness, material costs, and almost every armor stat can be tweaked in the balance.json file. Unfortunately, the same can not be said for weapons as of right now.
Bow Balance - To prevent bowmen from being the be all end all class, the bow weapon type has been slightly nerfed by halving movement speed while the bow is drawn. This can be mitigated by wearing silver armor, or if you don't like it at all, you can remove it by setting "baseBowDrawMoveSpeeed" to 1 in the balance.json file.
There seems to be an incompatibility with ValheimLibOpenDatabasePatch.dll, I'm currently investigating. TripleBronze also appears to be incompatible. EpicLoot IS compatible, but there may be balance issues if both are installed.
