Description
Enemies in the area fall into a frenzied state.

[Low Rank Shriek of the Dead Lv1 (Active)]

[Causes the enemy to lose their mind, and puts them into a 'frenzied' state. Additionally, they are afflicted with 'Fear' of the caster.]

[The Low Rank Shriek of the Dead skill has become Lv10 and has evolved into the intermediate level. You have continued to train this skill, which is nothing more than a mere scream; by doing so, you can utilize your karma to its maximum potential. You have created a skill whereby any who hear your cry will become dizzy and confused, and you may order them around as you please. The Joker's innate skill, Instigate has been born!]
