Arcane Veil with Hardened Veil looks good. You can get around 95 deflection with those which seems to rival tanks. You can also cast buffs on your self from other sources so it seems like a good emergency save me button for them.
Blast and Pentrating Blast are good too. Free cheap AOE attack. No downside
Grimoire slam looks like junk. Its only purpose is to break engagement. It doesn't stun or root them though so they can probably just jump right back in. It is also single target so if you are surrounded good bye. Veil looks like a better solution.
Bonus spells look like junk. You always have enough for any one fight. Most smaller fights you should just be burning through your regular per encounter abilities. Also you can get rings to add more and lower level become per encounter later.
Grabbing a single element damage spell seems like a good idea. Looking at the full spell list, Heart of the Storm looks best because of chain lightning. However, just pick the type you like.
Spells themselves seem pretty irrelevant. I have every level 1 and 2 spell at level six thanks to raiding other people's Grimoires. It will probably be the same for 3 and 4 at least.
You should probably have one talent left. I don't know about Dangerous Implements though it might be kind of cool. The damage you deal to your self is pretty tiny. There are also some defense regular talents to consider like fast runner, but those are all personal preferences.
