engineering job lvl max => Technomancy he should go to i reincarnated as a spider, with blue mage he would get a lot of skills and he should find out what happens with time dilatation and then spends time in a time chamber just lvling his skills and due to the replicator he will have all the material needed for craft skills (he won’t lvl up, but his power level will be over 9000!)
