Anti-Stealth Exploits: Classic And Retail (Patreon)
Content
Taken from classic bug report:
Bug: Mind Vision retains detection and targeting of stealthed players if cast on them before entering stealth. This works through Stealth, Prowl and Shadowmeld. I have not tested with Invisibility yet but it probably works too. The bug also allows for recasting Mind Vision, allowing permanent detection. You are also able to cast on the stealthed player when they come within range and put them in combat and pull them from stealth.
I tested this on retail but it does not work. However in the process I discovered that the X-treme Water Blaster Display (or rather the water pistol it produces) can take a player out of stealth.

This has quite a limited range but is useful against players who lack area of effect abilities without cooldowns.
