[Undead Wall] was a special Skill that the Blood Zombies had; its power was simply yet amazing. It could fuse two or more Zombies together into a grotesque wall of rotting flesh, unifying all of their defensive stats and enhancing their skills!

[Undead Wall]
As long as there's at least another Blood Zombie near the user of this Skill, the user and the target fuse into a [Temporary Summon] named [Undead Wall of Rotting Flesh] for 1 Hour. The fused Undead Monster combines all the Defensive Stats of its ingredients but cannot move. The level of the Skills it has is based in how many Zombies are merged together.
The [Undead Wall of Rotting Flesh] possess the [Dread Tentacle] [Rotting Breath] [Menacing Aura] and [Auto Destruction] Skills which it can use freely as long as it lives. After the hour passes, the Undead Wall will automatically Self Destruct or, if the master desires, simply disappear without leaving anything behind.
