I like the Shadowdancer prestige class concept; darting in and out of the shadows unseen. However, most of the class's skills are very situational unless you can create your own darkness, mostly through the 2nd-lvl spell of the same name. Reading through the classes that have access to Darkness, I came across the Dark Tapestry Oracle mystery, which seemed to match both mechanically and thematically.
1. I'll obviously need at least 4 levels of Oracle to get Darkness. Since I'll need to be 6th before I start SD (5 ranks Stealth), I'd considered getting a level or more of rogue to get some sneak attack dice. Will this hurt me more than it helps?
2. My thought was to take the Clouded Vision curse--as I understand it, by choosing Pierce the Veil for my first revelation at level 1, the curse is basically nullified, correct? And I'll get another 30ft of darkvision once I start SD too, right?
3. The most important spell to pick up would be Darkness, plus Dusk of Twilight that I get from the mystery. What other spells might work well with the concept?
4. I definitely want to get Spring Attack as one of my feats; with Mobility already being required for SD, it makes sense to go one more step to open up opportunities to pop out of the shadows, attack, and hide again. Are there other feats that would fit well?
