Gnome rogue 2 / wizard 18 focused on Illusion spells: something like 41 Feydark Illusionist / 25 Archmage / 14 Pale Master. If you skip PM, you'll have to find another way to self-heal: i.e., potions, UMD scrolls/wands, and/or hirelings. IIRC the gnome racial and Feydark Greater Color Spray SLAs are on shared cooldowns so there's no point in having both.
Strimtom had a
similar build on the old forums, it just needs a few tweaks for regular gnome. Deep Gnome can have two Phantasmal Killer SLAs (one racial, one Archmage) plus the regular spell; but it costs a lot of APs so it's not something I would recommend for a first-lifer. Plus not everyone has DG unlocked, obviously.
