Slayer Legend: How to Awaken Class 20 Nova to Tera

To awaken Class 20 (Nova) to Tera in Slayer Legend, you must acquire two duplicate unequipped copies of Class 20 and consume them sequentially through the Class menu. Reaching the Tera tier requires a total investment of roughly 1,000,000 Diamonds dedicated entirely to the Class Summon banner to push summon level pity milestones.

Class 20 Awakening Stages and Requirements

Awakening Nova advances the class through two distinct promotional steps beyond its base form. Each stage consumes one duplicate Nova and permanently increases your equipped Attack multiplier alongside universal owned effects.

Awakening Tier	Required Duplicates	Primary Benefit
Base Nova	0 (Initial unlock)	Baseline equipped multipliers and owned stats
Giga Nova	1 unequipped C20 duplicate	First major boost to Extra ATK and owned effects
Tera Nova	1 unequipped C20 duplicate (2 total)	Maximum C20 equipped multiplier and permanent owned attack scaling

Because natural drop rates for Grade 20 items are exceptionally low, targeting two duplicates relies on raising your Class summon level. Spending approximately 1,000,000 Diamonds on the Class Summon banner advances the summon progression bar, triggering pity bars and reward milestones that yield high-tier classes. Avoid splitting your Diamond budget across multiple banners during this push so your Class summon level can reach higher baseline drop tiers for C18, C19, and C20 rewards.

How to Awaken Nova in the Class Tab

Once your summon session yields the required duplicate copies, perform the promotion manually:

Open the Class inventory tab and select your equipped Class 20 (Nova).
Confirm you hold an unequipped duplicate Nova in your inventory. Do not use auto-combine or batch-fuse features, which might accidentally merge high-tier classes.
Select Awaken to consume the first duplicate copy, upgrading Base Nova to Giga Nova.
Confirm your second unequipped duplicate copy is available in your inventory.
Select Awaken a second time to promote Giga Nova to Tera Nova.

Awakened tiers are permanent account upgrades that preserve all previous enchant levels. The owned stat increases remain active at all times, even if you switch your cosmetic appearance or equip a different class.

Progression Timing: When to Spend 1 Million Diamonds

Committing 1,000,000 Diamonds to class summons carries a high opportunity cost. Sinking this volume into classes before establishing your weapon foundation can stall overall account growth.

Wait if: You are still working toward essential early weapon milestones, such as acquiring your Mythic 1 (M1) sword or making initial progress toward crafting the Orr weapon.
Commit if: Your weapon summon levels have reached diminishing returns, and promotion bosses or stage HP scaling have created a damage plateau.

Once your basic weapon progression is stable, directing a 1,000,000 Diamond reserve into Class Summons provides the concentrated attack multipliers needed to clear strict mid-to-late-game DPS checks.
