I guess that's good enough for a basic introduction… Though if you only want an ethereal version of set gear, that's obviously not relevant. That's either good or bad news depending on how you look at it… atm details are pretty much unkown, which floor yields which grace bonuses, if it's tied to the floor number, or the boss, how many levels you completed etc. However it appears that leaving at certain floors only yields certain Grace bonuses from defilement. So bascially if you want Ethereals you have to leave with your gear at floor 31 or above, you have to leave at higher floors if you want higher + Level (the 50+ floors are still below 40 though). I think if you haven't cleared WotS it won't let you past Level 5 in the Abyss, certainly not past 10. You have to clear the respective difficulty, or the game won't let you advance further e.g.
The floors and the gear you can obtain are roughly equivalent to the difficulties in the gameġ-10 Wot Samurai/Strong, gear up to 160(+10)Ģ1-30 WotW, up to 260(+30), Ethereals start to dropģ1+ WotN, up to base Level 310, + Level starts at +35ish and keeps slowly rising to around +135 at 999 (the last floor), Enemy Attack and Defense keeps rising but seems to stay in line with the gear drops. Yes the chances are pretty high actually, like 80% I'd say if you increase the defiled items bonus to 3 on a piece of gear.
