Est of Sloth

Est of Sloth (怠惰のエスト Taida no esuto) is a boss in Succubus Puttel associated with one of the seven deadly sins, specifically (deadly sin) sloth (acedia in Latin).

Strategy
Est begins the battle by using Deadly Sin: Sloth, which prevents you from acting for several turns. She follows this by using a Hold that seals most of your skills. To survive the initial assault, you should begin the battle with full Vigor and no Lust, then struggle out of the Hold as soon as you can act again.
