i think there really is only 2 answers to this.
If your PUP is 37 or below, go Something75/PUP, the automaton can skillup that way.
go to beadaux with the whm automaton up go to the curse machine and deploy it on a mob it'll spam cursna till it's out of mp.
i did this /dnc when i got up in the 60's or so. low lvl is more work. maybe a refresh with /whm for regens and cures? wear your eva+ stuff. hit a pug by the curse thing. deploy puppet, run out of melee range. the puppet will sit and cursna and wont hit the mob. mob will keep hitting you since you have most hate from that 1 hit in the beginning. put a dark up for refresh. maybe 2. and just wait.
does it take a long time? yes.
will you see lots of skillups? yes.
is it faster than trying to find a dc and fighting it in hopes of 1)no dying, 2)spells actually cause a skill up, 3) there being lots of mobs.
just do #2.
