Hi, discovered this by common sense, though it took the correct order to actually make it useful.
Engineering with a lvl of 425 is required!
1. Use Synapse springs
2. Use Camouflage
3. Stand still so that you character can be put in stealth
4. Walk around for about 10 sec with very high opacity (transparency)
( The effect is stacked so that the opacity you get while in stealth when running around to!)
My conclusion is that any effect similar to the Synapse Springs can be used this way!
To gain some time you can also create a macro that looks like this... just for dummies =P
/use "The name of the gloves"
/cast Camouflage
