🧬 Mastery Chain Link System

Mastery Chains are an end-game PvM enhancement system in Ultima Online: Outlands. They are wearable talismans that provide passive, scalable bonuses—boosting damage, resistances, healing, utility, and dungeon effectiveness.

In Pax Mercatura, mastery chains are operational assets. They are deployed to our combat elements—mages, dexers, summoners—and optimized per billet to improve survivability, damage throughput, and loot efficiency.


Tier Description Max Bonus Power
Bronze Common, affordable, tradeable Up to +5%
Silver Rare, obtained via events and PvM rewards Up to +10%
Gold Ultra-rare, elite-tier PvM assets Up to +15%

Mastery Chains can hold up to 30 links. You unlock new link slots by earning PvM experience. Links must be installed using Arcane Essence, and link XP is shared across your account.


🧠 Deployment Facts

  • Equipped in the Talisman Slot (must be equipped once to bind it to your character).
  • Bonuses activate 30 seconds after equipping or swapping a chain.
  • Chain XP is earned from any gold-generating PvM activity (kills, chests, etc.).
  • XP is account-wide, but each character needs their own chain to benefit.
  • Bonuses do not apply in PvP or within 30 seconds of PvP combat.
  • Players can own multiple bound chains and switch them based on roles.

🔧 Chain Management

  • Use [MasteryChain to open the chain interface.
  • You can install links automatically with the “Install All in Backpack” button.
  • You can remove links at any time, but Arcane Essence is not refunded.
  • Links are capped: up to 10 of the same bonus effect, except for special/rare loot bonuses (max 20).

🎯 Combat Tips

  • Use slayer links that match dungeon or monster types: undead, daemonic, etc.
  • Stack template-specific links: spell bonuses for mages, melee modifiers for dexers.
  • Avoid wasting Arcane Essence on low-tier effects. Prioritize synergy with aspect gear.
  • Coordinate with your Centurio for optimal link selection per assignment.

📦 Loot & Sources

  • Omni Bosses
  • Lore Books and Tomes of Heroism
