Deeper and Darker Gear: Resonarium and Warden Sets
Deeper and Darker adds two tiers of tools and armor above vanilla, both applied through smithing. This guide covers the Resonarium and Warden lines.
Resonarium gear
Resonarium is the mid-tier upgrade, applied to diamond equipment with a 
Resonarium Plate and a smithing template. The full line covers tools and armor:
- Tools —
Resonarium Sword, 
Resonarium Pickaxe, 
Resonarium Axe, 
Resonarium Shovel and 
Resonarium Hoe, each from the diamond tool plus a Resonarium Plate. - Armor —
Resonarium Helmet, 
Resonarium Chestplate, 
Resonarium Leggings and 
Resonarium Boots.
Warden gear
Warden equipment is the top tier, upgraded from netherite with a 
Reinforced Echo Shard and a smithing template:
- Tools —
Warden Sword (and the matching 
Warden Pickaxe, 
Warden Axe, 
Warden Shovel and 
Warden Hoe), each from the netherite tool plus a Reinforced Echo Shard. - Armor —
Warden Helmet, 
Warden Chestplate, 
Warden Leggings and 
Warden Boots.
Progression
Build the Resonarium set first from diamond, then convert your netherite gear to the Warden line as you accumulate reinforced echo shards. Because both tiers reuse the same smithing flow, the limiting factor is the Otherside materials — resonarium plates and echo shards — rather than the crafting itself.
