12k isn't enough imo, technically you can do everything (probably gonna die if you sed in HT but im not sure). But I personally dont like being dependant on DP or forgetting meso guard. A better goal would be 17.5k You can have the 17.5k goal at a higher level and take your time questing there, its fine too. 400 from raul is a tiny amount, thats only ~12 quests. I dont think that 50 int + 40 equips would get you 165 washes (by what level?) but I didn't do the calculation, add the spreadsheet screenshot here if you got it. You kinda have to have the int as early as possible, otherwise you are loosing a lot of mp.
Hey, idk about shad washing, but depending on the speed of your progress (have 1/2/4/6 hrs a day? Matters a lot!) you can pretty much count a lot on the elixir of life hp quest of 120+. For example, if you gonna take about 2 months anyway from 120 to 135, you can just opt to do 1 hp quest every day (avg of 15-20 min/day with a shad) and count on an avg of 1050hp/month. Which then means 2k in 2 months and gives you a lot of breathing room. Also, if you suddenly decide to play some other chars for a bit and keep hp questing every day, it accumulates faster than you'd think. I have a 13k hp NL with no washing, some int gear but very minimal, spent some 50 aprs on him, level 148. Another thing you can do is go for the collector medal. Level 3 medal is 500 hp, 2att. Level 4 is hard to get but is 1k hp and 3att. Although this might not be BiS for a 3-stat class like a shad. In general, the elixir quest is very good for those of us who worry too much about not being able to fix our hp due to the lack of int early game. Realizing that a month or two of patiently hp questing can fix our hp at ANY point in time is Un-stressing. GL
