The 2025 Worm Cult season of The Elder Scrolls Online (ESO) introduces a powerful feature: Subclassing. This system allows you to expand beyond your base class and incorporate skill lines from other classes, offering an unprecedented level of customization. Whether you’re building a hybrid DPS, tank, or support, subclassing lets you tailor your character in exciting new ways. This guide will walk you through everything—how to unlock it, limitations, leveling mechanics, and best practices to get started.

What is Subclassing?
Subclassing allows your character to retain at least one skill line from your original class while replacing the other two with fully unlocked skill lines from other classes. This means a Dragonknight, for example, could keep one Dragonknight line and swap the other two for Sorcerer, Warden, or Arcanist lines. You can only add one skill line per other class, preserving class identity while providing flexibility.
Why Subclassing Matters
-
Unmatched flexibility: Access new gameplay styles without creating separate alt characters.
-
Creative builds: Combine skills for unique combos—like healing abilities from Templar with summoning from Arcanist.
-
Preserves investment: Your main character evolves without restarting the leveling grind.
How to Unlock Subclassing
-
Reach Level 50 with any character.
-
Complete the quest “A Study in Discipline”, which can be initiated from select NPCs located near Wayshrines in Riften, Evermore, or Dune, or accessed through the quest menu.
-
Once completed, you’ll unlock the subclass interface and be able to select up to two additional skill lines from other classes, while keeping one from your base class.
Subclassing Mechanics & Restrictions
-
Minimum one original line: You cannot fully depart from your starting class.
-
One line per other class: Prevents mono-class exploitation.
-
Skill lines must be fully leveled to 50 on your account before they become freely swappable.
-
Unlocked skill lines occupy leveling slots until you master them—once mastered, they become infinitely flexible.
Leveling Subclass Skill Lines
Every subclass skill line needs to be leveled from scratch—even if it’s mastered on another character. Expect:
-
Slower progression than normal class lines.
-
Double the skill point cost per ability.
-
Separate experience tracking per account, not per character.
After hitting Rank 50 on a subclass line, it’s fully mastered and can be freely swapped without consuming a leveling slot.
Changing or Removing Subclass Lines
Once unlocked, you can respec a subclass skill line by visiting a Rededication Shrine or speaking with the subclass NPC, Bahtra at-Hunding. Changing costs a flat 1,500 gold and refunds all spent skill points on that line—work similarly to regular ability respecs.
Best Practices for Subclassing
-
Keep at least one class line you enjoy to maintain core gameplay identity.
-
Plan builds ahead—swap lines only when you can level them efficiently.
-
Master first, then experiment—don’t keep leveling the same lines repeatedly.
-
Use the Armory Station to save your favorite skill line setups for quick swaps.
