Which level ranges would you adjust? My experience leveling is -quite- out of date by now, so I depend upon feedback to alter the level ranges for camps and stuff in the guide.
As for the OP, I wouldn't worry much about traveling as an Iksar. It isn't bad. Circlet of Shadow definitely helps, but with Feign Death banking, and knowing where to find Iksar friendly merchants (see a
new section in my guide), it isn't bad at all. Getting Freeport/Qeynos merchant faction is a joke (30 minutes, a druid friend, and 20 plat on Rohand's Brandy), which greatly increases your merchant friendliness. At 34 with Call of Bones for Neriak, and other evil cities... Not tough to manage. I would definitely make earning money a priority, so aim for cash camps (Sisters, Gargoyles, Treants) rather than XP camps. The price on Circlet of Shadow wont rise too incredibly fast, thanks to how many people have been saving them, but the sooner the cheaper. It is the single best clickie on this or any character I play. Mixing it with Feign Death is just great.
I also agree with Ando above. Utility items are priority. For me, though, I'd keep CoS, Jboots, Goblin Earring, Words of Darkness, Bracer of the Hidden, Leatherfoot Raider Skullcap, Wand of Darkness, Mage Clickie Reclaim Energy item, and utility staffs (Fear stick, debuff stick, etc). I also wouldn't skimp on cheap HP gear like 65 HP rings. They are low cost, high impact.
