Im a lvl 1 sorcerer
I wanna use staffs and ive been reading all this stuff on Implaments, im new to DnD 4.0 and wanna know how i go about getting Implaments, do i find them buy them train into them? I'm not sure and which ones i can use at lvl 1 if any and what all the feats are for implaments. I see staff fighting and arcane implament and implament expertise and weapon focus (staffs) and im unsure which ones will stack and what wont thank you.
The sorcerer is a striker, using spells. A staff is both a weapon and an implement. Since the sorcerer's spells are so much stronger than its melee attacks, it's the implement side you want to focus on.
The sorcerer starts out proficient with the staff as a weapon and uses the staff as an implement automatically. A staff costs 5 gp (a ridiculously high price) but you start with 100 gp, so buy one with your starting cash.
A staff gives a +2 proficiency bonus to attack rolls (when using it as a weapon, not an implement). This has no effect whatsoever on spells.
An implement is, for all intents and purposes, a magic weapon for a spellcaster. Once you get a magic staff and use it as an implement, it gives you bonuses to hit and damage when channeling spells through your staff. Magic staves also give you bonus damage when you score a crit and some have other special properties. You won't start with a magic implement, you'll just have a regular one, which gives no bonuses by itself. (The Staff Expertise feat will give you bonuses even without a magical staff.)
The sorcerer is in Player's Handbook II. Heroes of the Fallen Lands (the first Essentials book) holds the Staff Expertise feat, which gives +1 to hit with implement powers at heroic level, and does not provoke opportunity attacks for making ranged or area attacks. If your DM allows it, take this feat!
There is rarely a good reason for your sorcerer to take the Weapon Focus (staff) feat. It only gives you +1 damage to staff
melee attacks. However, if you're a draconic sorcerer, you'll have a decent Strength score, so it won't be totally worthless. (I would still recommend using a close blast power if you get pressed into melee.)
You don't need any staff fighting feat.
When you mentioned "Arcane Implement", I wonder if you're thinking about the wizard. The PH1 wizard can choose the Staff of Defense ability to deflect attacks. This is something the sorcerer
cannot do. The sorcerer has other defensive abilities instead.
