Yaya
Yaya had an unfortunate childhood. He was abandoned because of his ugliness. Never knowing love, Yaya became vicious and cruel.
He rejected everything in the human world.
For nothing more than a taste of soup, Yaya agreed to become a subject for a wizard's experiments at the age of sixteen. Hundreds of people perished in these cruel experiments, but Yaya lived. He became half man, half monster.
His new monstrous power was well suited to his selfishness and viciousness. He walks the world as a nightmare. Today, the name Yaya is synonymous with death.

Skill Summary
Stealth and mobility- Attacks like Shredding Bite and Demonic Crunch use teleportation and illusions to increase damage.
- Backstab skills (Nightmare Stab, Assault Backstab) deliver high physical damage and can grant invisibility.
- Lurking Shadow Abyss provides temporary invisibility with bonus damage and armor penetration.
- Physical Liberation and Smashing Claw pull enemies, deal area damage, and heal.
- Assimilation & Devour and Ashura Body consume enemies to expand maximum health and damage, with extended limits.
- Buffs like Monsters Friend, Mutated Body, and Demon Armor increase health and reduce damage for monster units.
- Monster Scale and Ruthless Monster enhance damage against light armor and boost critical hits.
Special highlight
- The combo Monster Companion + Assimilation & Devour is the core strength of this tree. Example: Yaya starts with 10k base HP, giving us +5k instantly. When he gains +50k from Assimilation & Devour, his total reaches 60k, while we get +30k. This pushes our hero from ~10–14k base HP to over 40k, while Yaya holds 60k.
- Important: our bonus HP is linked to Yaya in real time. If he dies and the effect ends, our HP drops too. Always protect him — give survival gear, don’t let him rush alone, and set him to follow our hero or guard the camp.
In summary: this tree combines teleportation, stealth, and devouring mechanics with monster-focused buffs, highlighted by the maximum health combo that makes the hero exceptionally durable and dominant in combat.
