Getting one of the rarest units in Manhwa Legends is already exciting, but pulling Sung Jin-Woo’s Dad with the 0.1% Legend Trait is on another level. This unit is built to dominate bosses, scales throughout the match, and becomes even stronger the longer the game lasts.
What makes him stand out isn’t just his raw damage. His unique stacking mechanics, boss-killing passive, and Full AoE attacks make him one of the strongest late-game units currently available.
If you’re wondering how to unlock him, evolve him, and whether he’s actually worth investing your resources into, this guide covers everything you need to know.
Manhwa Legends Sung Jin-Woo’s Dad Guide – How to Get, Evolve
Sung Jin-Woo’s Dad is obtained through the Raid content in Manhwa Legends.
You’ll need to repeatedly clear the Raid to collect the required evolution materials and Raid Currency.
The farming process isn’t particularly difficult if you already have a strong team, but it can take some time depending on your luck and how efficiently you’re clearing runs.
If you’re farming solo, bringing high DPS units makes the grind much faster.
Evolution Materials
To evolve Sung Jin-Woo’s Dad, you’ll need several items.
Required Materials
- Light Scroll
- Promise
- 2 B-Grade materials
- 1 C-Grade material
- Gold
Most of these items can be obtained from the Raid Shop.
Where to Get the Light Scroll
The Light Scroll is purchased from the Raid Shop.
It costs 30 Raid Currency, so if you’re slightly short, you’ll need a couple more Raid clears before purchasing it.
During the game’s early release, crafting the Light Scroll was temporarily unavailable because of a crafting bug, making the Raid Shop the only reliable option.
How to Evolve Him
Once you’ve collected every material:
- Visit the Evolution NPC.
- Select Sung Jin-Woo’s Dad.
- Insert:
- Light Scroll
- Promise
- 2 B Grades
- 1 C Grade
- Pay the Gold cost.
- Confirm the evolution.
After evolving, the unit receives:
- 50% increased damage
- New Skill: Ruler Storm
- New Passive: Ruler’s Vessel
This is where the unit truly starts becoming powerful.
Passive Skills Explained
The evolved version has several unique mechanics that make him scale throughout long battles.
Ruler’s Authority
Every attack grants one stack.
At 10 stacks, he enters Ruler’s Authority II, gaining:
- 100% Critical Chance
- 10% lower SPA (attacks faster)
Unlike many units that require their final upgrade before unlocking powerful effects, Sung Jin-Woo’s Dad reaches this buff simply by attacking.
Wave Scaling
For every completed wave, he gains:
4% additional damage.
One interesting detail is that the passive doesn’t mention a maximum limit.
If that’s intentional, it means his damage continues increasing for longer Infinite Mode runs.
Boss Slayer Passive
Whenever a boss appears:
- Every stored stack is consumed.
- He gains 8% bonus damage per consumed stack until that boss is defeated.
This makes him incredibly effective during boss waves.
Instead of slowly building damage, he unloads massive burst damage exactly when it’s needed.
Ruler’s Authority III
After reaching 20 stacks, another transformation activates.
Additional bonuses include:
- 25% Critical Damage
- 50% extra Range
- Applies Bleed for 8 seconds
At this stage, the unit becomes significantly stronger than his earlier upgrades.
Upgrade Progression
Even without perfect stats, his upgrades scale nicely.
Some notable milestones include:
| Upgrade | Performance |
|---|---|
| Placement | Small range with decent damage |
| Early Upgrades | Damage steadily increases while maintaining good attack speed |
| Mid Upgrades | Unlocks Ruler Storm and begins scaling much faster |
| Late Upgrades | Range improves considerably |
| Final Upgrade | Gains Full AoE and massive damage increase |
The final upgrade completely changes how the unit performs.
Instead of attacking a limited area, he begins hitting every enemy within his attack radius.
Final Stats
At maximum upgrade, the showcased version reached roughly:
- 32,000+ Damage
- 4 Second SPA
- Full AoE
- 100% Critical Chance
- Bleed Damage
- Increased Critical Damage
- Increased Range
These numbers were achieved without perfect stat upgrades, meaning fully optimized versions can perform even better.
Damage Against Bosses
This is where Sung Jin-Woo’s Dad really separates himself from other units.
During the showcase:
- Boss spawned.
- Passive stacks were consumed.
- Damage increased to roughly 46,700 per attack.
- Bleed remained active.
- Critical Chance stayed at 100%.
The boss was eliminated almost instantly.
Because of how his passive converts stored stacks into bonus boss damage, he excels in Raid content where bosses have significantly higher HP.
