2.4.2 What is the benefit of Sneak-Hide?
Using sneak and hide at the same time (Sneak-Hide) allows a rogue to move while invisible to most mobs and players
! The rogue is "invisible" to most mobs and players with the exception of those that can cast "See Invisible". Unlike the spell "Invisibility", sneak-hide has unlimited duration until turned off (like Hide), a spell is cast on the rogue by a spellcaster/bard, or the rogue zones. Sneak-Hide also works against both Undead creatures and regular creatures. However, there is always a minute chance of any mob seeing through your Sneak-Hide and detecting you. Starting at 51st level, you begin to move faster while sneaking.
By 60th level, you are at a full run, and this combines with any speed spells.
This skill is highly valued for maneuvering in dungeons, scouting or corpse recovery.
