Yeah, Staff is confusing right now. Turns out Character Builder will allow you to use the Staff Fighting feat (Dragon) to turn a staff into two implements, and thereby get a damage bonus from one staff's other end (... for the price of two feats, 13 dex, and 13 wis).
Some good suggestions here, but some things you should wait on, too.
For example: Dual Implement is groovy iff you have a spare +2 or better implement for your off-hand. At 1st level, when you have no magic implements, it's useless. And remember, Weapon Focus turns into +2 at Paragon level, so take that at 10th if you don't have a pair of +3 weapons.
So, here's my advice:
- Leather Armor Proficiency
- Arcane Reserves (great at 1st level, retrain it at 6th or 8th when you have several Encounter powers)
- White Lotus Riposte (especially if you can't seem to stay out of melee, or if the DM likes to throw ranged attacks your way)
- Reaper's Touch (IF you have Acid Orb or Dragonfrost, and take this after White Lotus Riposte, and only if you just can't keep out of melee)
- Action Surge (6th level, when you have two daily powers, so you'll get approximately one action point per daily attack).
- Focused Expertise (Dagger)
- Sly Dodge (Rogue Multiclass; unlocks Daggermaster; also nice AoO negation once per round)
