I would challenge the Dev's to build a perceptive rogue/mage with enough AP and HP to be effective in combat (hard difficulty). Without using books this is largely impossible unless you get massive RNG luck or savescum chests for gear.
Focusing on three things is asking for trouble, even with the books. Try to narrow it down to two, unless you just like playing a Jack-Of-All-Trades / Master-Of-None.
