Slayer Legend: How to Unlock the Nova Class (C20)

To unlock the Nova Class (Class 20) in Slayer Legend, synthesize five duplicate Class 19 classes in your inventory. While Nova can theoretically appear as an ultra-rare direct drop from high-level Class Summons, the reliable method is raising your Class Summon level to generate enough duplicate fodder to merge upward.

Synthesis Steps to Forge Nova

Classes merge upward at a strict 5-to-1 ratio. Reaching Class 20 requires a chain of lower-tier duplicates:

Synthesize baseline tiers: Use the automatic combine feature to merge excess Class 16 and Class 17 duplicates into Class 18s.
Create Class 19 copies: Combine five Class 18 duplicates to produce a single Class 19.
Accumulate five Class 19s: Repeat the process until you have five copies of Class 19 in your inventory.
Merge for Nova: Combine the five Class 19 copies to receive Class 20 (Nova).

Do not dismantle high-tier class duplicates for secondary currencies while working toward Nova, as every copy from Class 16 upward serves as material for this synthesis path.

Recommended Summon Level Targets

Chasing Nova requires substantial diamond spending on the Class Summon banner. However, doing so before establishing a baseline weapon setup slows overall account progression. Secure your core Mythic weapons and lay the groundwork for the Mythic weapon Orr before dedicating all diamonds to class pulls.

Account Stage	Diamond Priority	Class Summon Target
Early Account	Weapon Summons (Grade 1 Mythics)	Level 3–4 (Base class buffer)
Mid-Game Transition	Balanced Weapon & Class Summons	Level 5–6 (Farming C16–C17)
Nova Push	Dedicated Class Summons	Level 7+ (Fusing toward C20)

Pushing your Class Summon level to Level 7 and above significantly increases the drop rates of Class 16 through Class 18 fodder, drastically reducing the time required to fuse five Class 19s.

How Nova Impacts Your Stats

Nova provides two distinct offensive boosts:

Equipped Effect: Active only when Nova is chosen as your equipped battle class. It provides the highest attack percentage multiplier available among standard classes.
Owned Effect: Activates permanently the moment Nova is forged, stacking additively with the owned bonuses of every other class you have unlocked.

Because owned effects apply account-wide regardless of which class you equip, obtaining Nova permanently elevates your base damage across standard stages, offline farming, dungeon content, and companion scaling.

Next Steps After Unlocking Nova

Once Nova is in your bag, stop spending diamonds on Class Summons. Continuing to pull classes immediately after securing Nova yields sharp diminishing returns. Instead, pivot your resources into areas that multiply your new stat baseline:

Resume Weapon Summons: Redirect diamond income back into weapon pulls to craft or awaken Orr, which provides the base attack that Nova’s multipliers amplify.
Enhance Nova Directly: Invest Enhance Cubes and class enhancement scrolls into Nova to increase its level and equipped bonus percentages.
Test Promotion Battles: Attempt previously stalled promotion ranks such as Dragonos, as Nova's damage spike often clears DPS barriers immediately.
Upgrade Active Skills: Level high-scaling burst skills like Blizzard, Hellfire Slash, or Demon Drive to capitalize on your increased damage ceiling.
