For 1v1 fights deception items are enough.
For aoe, glitterdust or sleet storm scrolls
You could do other stuff tho, use radiance guard gsteel or radiance gsteel weaponry /issue if you are after wraps builds.
Im not sure if the t2 thforged paralyze thing grants sneak, my guess is no.
Also trip while the dc is fucked up helps alot, balanced attack give auto sneak.
THere are really many ways, but for aoe sneak you need to focus on scrolling and preping battlefield which is a bit annoying currently.
ANother fun option is to mess around with traps, there are some that give amazing effects.
Here in this video you can see how a standard 2 weapon fight sneak based rogue ranger figh plays around with traps for sneak/cc in ee content.
Is a friend and most of the trap mats are from me heh

I personally dont find it impressive, but its ok since he is a stubborn rogue main only player since 2008
