Stealth

Stealth reduces the range at which a monster will aggro a target. If a monster would detect a target within its visibility range that has reduced visibility, the range is checked again with reduced visibility applied.

Reduced visibility range from stealth is multiplicative, not additive. For example, at 200% increased stealth, monsters have a 66% reduced visibility range.

Version history

Version	Changes
3.12.0	Removed the concept 'Reduced Visibility to Enemies' and replaced it with 'Stealth'. Increasing your Stealth reduces the radius at which enemies will notice you. 100% increased Stealth cuts that radius in half, and 200% increased Stealth cuts that radius by two thirds. You can, therefore, no longer become entirely invisible to enemies.
