well well. got a lot of intersting hints there so i feel free to give my 2 influs..
make a lot of arachnos scanner missions... alone, invincible.
end mission bonus 50 on 53 mission si about 50K.
and arachnos drops all kind of interesting schems...
this is for Blast part.
regarding Ice Tank part, CoT is far more interesting, as there's a lot of ice thorn and/or demons.
works great.
missions freeing someone or getting an object are done faster than the others... to my PoV.
works better than being RSK on low level missions...
tried on lvl 14... boring, not fast, death at the corner...
works faster on invincible scanner mission.
