While I love the concept of adding Plate Armor Set and an updated recipe to incorporate copper into the Traveler Gear Set, it feels somewhat limited due to the rate of the materials used. The traveler gear set suffers from the same issue as the leather armor set in that usually by the time you've collected enough leather that you would probably have enough iron collect to make iron armor instead.
And speaking of iron armor, the Plate Armor made of Cobalt is fine for end-game play, but there's no form of mod armor for early-mid to late-mid game. Suggestion for this is to add lower tiers of Plate Armor such as Copper, Iron, and Gold, and then alter the armor stats accordingly; Iron having less armor and no toughness compared to cobalt, gold and copper having similar armor but gold having an additional upgrade/ability compared to Iron and cobalt.
Probably even add more end-game plate armor such as diamond, emerald, and the tier 3 materials.
This is based on if the team is staying with doing crafting recipes via the crafting table instead of creating patterns for armor for crafting in the Tinker Anvil in a later implementation.
Any chance we can get the Beheading effect to be modified to drop spawn eggs? With a lot of packs using apotheosis you really need them to create certain mob spawners. And as you can not enchant TC weapons to have capturing, you often have to use a weapon for this purpose.
