|Turbine has foreshadowed changes to invisibility and stealth to bring D&DO closer to the core rules:|
In order to bring the stealth and invisibility systems closer to the D&D Core Rulebooks, we’re redesigning how the systems work.
Monsters that think they have detected a hidden target will no longer unerringly home in on the stealthed character. Now, alert NPC’s will begin making “best guess” attacks near the last suspected location of their target (the last location they either saw their opponent, or heard them if they made noise), and will search in a progressively wider radius until they find their foe. A monster that physically bumps into a stealthed player will automatically detect them and begin attacking.
