Madman's Knowledge ❘ 狂人の智慧	Consumable

In-Game Description Skull of a mandman touched by the wisdom of the Great Ones. Use to gain Insight. Making contact with eldritch wisdom is a blessing, for even if it drives one mad, it allows one to serve a grander purpose, for posterity. Note 1: The same in-game description in US & UK versions. ✓ Note 2: Original Japanese text on Original Japanese Item Index page. ✓ Overview Insight is inhuman knowledge and represents your awareness of the nightmare's effects. In addition to its use as a currency at the insight shop and during multiplayer, acquiring more insight provides certain benefits but also poses a few risks. High levels of Insight will decrease your Beasthood stat, and while that does mean that you will fill the Beast Gauge faster, you won't be able to reach the later damage modifiers that come with a bigger gauge. Your Frenzy resistance is also heavily dependent on how much Insight you have, and the more you have the more susceptible you will be to getting Frenzied. Some enemies and aspects of the environment will also change at particular insight thresholds, such as the Church Servants in the Cathedral Ward gaining powered-up weapons and new attacks; with extremely high insight you'll also become able to see things during the day which would otherwise only be visible when the Blood Moon is out. Effects Grants one point of Insight when used. There are clear benefits of having these insight items in your inventory and use them only when you are in need of Insight, either to spend them at Insight Bath Messengers in Hunter's Dream or to call cooperaters into your world. This way you will avoid negative effects described in Overview section.
