Dim Vision

Key details

• Player vs Player: This curse will not work on other players.
• This will not work on Super Unique Monsters and Bosses.
• Dim Vision is effective against Ranged Attackers including Dark Archer or spell casters with dangerous ranged spell attacks.
• Dim Vision will prevent monsters from seeing you which will allow you to attack them from a distance, but they will be unable to hit you back.
• It is also effective to cast on a monster to limit their ability to follow you so that you can escape.
• Dim Vision will not overwrite a monster Cursed with Attract or Confuse (but can be overwritten by them).
• A monster with Dim Vision that is attempting to close into melee range with a target will continue doing so indefinitely until it hits an obstruction of some kind (if you cast Dim Vision on a creature that is attempting to close to melee range with you, it will continue following you, even if you move, until it hits an obstruction of some kind).
• Dim Vision prevents the AI controlling the unit from deciding on a new course of action (apart from melee attacking something that's in range).
• This explains why, when Dim Vision (or a Dim Vision-like effect) overwrites Terror (or a Terror-like effect), the affected creature will continue running away indefinitely until it hits an obstruction or the Dim Vision effect wears off.
• Dim Vision also usually prevents monsters from using their special attacks and abilities.
• This means that Blood Lord cannot cast Frenzy, for instance. (Similarly, Vile Mother cannot create spawns, Frozen Horror cannot cast Arctic Blast, etc.) The sole exception appears to be that if the creature's only attack is a ranged attack (including Burning Dead archers), it can still use that attack against creatures in melee range.
• Oblivion Knight in the Chaos Sanctuary are immune to Dim Vision.
• This can be quite frustrating since they can fire Bone Spirit through their blinded companions.
• Switching to Decrepify against these creatures and/or resummoning your Golem next to them is usually your most effective strategy.
• Dim Vision is especially great on Hardcore mode.
• With maxed-out Dim Vision and some +skills items, you can hit more than the entire screen.
• If you take care you will never face a normal enemy that can see you.
• It is also helpful in a party setting since Dim Vision makes many melee monsters less fearsome by disabling their Charge & Frenzy-type skills and ensures that melee party members can run away and heal for a bit if things get too intense.
