Bigskull Drake
Dragon Ghost Phase I Original Form
When first discovered, the Big-Headed Ancient Dragon slumbered deep within underground rock strata, knowing nothing of the modern world or creature society. Its skeleton is not only hard but regenerative—even broken bones can regrow in short time. Though its bony wings appear fragile, they are remarkably resilient.

Immortal Consumption Build
Playstyle
Use Dragon Blood's 70% damage reduction and Stance healing to stay on field, intentionally sell HP to trigger Immortal resurrection, after resurrection use full status + Dragon Blood/Stance's charge-free mechanism for counterattack, Dragon Claw lifesteal maintains HP line, forming infinite attrition loop.
Why this set works
A drain revival build centered around trait 'Immortal' and extremely low speed, using Dragon Blood + Stance dual recovery/damage reduction system to delay until revival, Dragon Claw as core damage with lifesteal sustainability, and Deceptive Thorn as low-cost cleanup means.

Notes
- Big Skull Dragon is a Dragon + Ghost dual-type with a high base Physical Attack of 109, only 40 Magic Attack, and extremely low speed of 48, positioned as a low-speed physical attacker tank.
- Trait 'Immortality' provides revival after 3 turns, combined with high damage reduction skills for extremely strong attrition capability.
- Wide weakness coverage (Ice, Dragon, Cute, Light, Ghost, Dark); beware of type disadvantage matchups.
- Skill pool focuses on Physical damage and defensive skills, lacking buffing options. Playstyle leans toward attrition and counter-attacking.
