Summon additional volatile zombies of Dreadful horde node needs zombie’s move before appearance additional zombie.
In my sense, “summoning additional zombies per cast” means can summon at the same time such as vines of Spriggan form.
This issue causes lower damage against enemies when zombie volatile before zombie’s move.

(Especially in the boss / tough enemy battle, this issue is notable when combined Beyond Death node of Dread Shade skill.
Because if zombie are volatile in close range before moving, so it causes only single volatile damage.)
