I'm in the middle of building a similar cleric.
At what level are you starting this cleric off?
The character is a Multiclass, not a Hybrid. Base Class Cleric, obviously.
As for feats, the list of what I am proposing to take is provided in the link above... but I suppose I could post the list here, if thats more convienent.
Heoric Tier, Multiclass Cleric/Invoker
1. MC Invoker: Acolyte of Divine Secrets
2. Versatile Expertise {Staff, Holy Symbol}
4. Healer's Implement
6. Defensive Healing Word
8. Superior Implement Training {Staff, Accurate}
10. Coordinated Explosion
Paragon Tier, Paragon Path ~ Morninglord
11. Battle Intuition
12. Invoker's Blaze
14. Invoker Implement Expertise
16. Radiant Vessel
18. Channel Divinity: Solar Enemy
20. Improved Defenses
Epic Tier, Epic Destiny ~ Soul of the World
21. Supreme Healing
22. Beatific Healing
24. Invoker's Aura
26. Glorious Channeler
28. Punishing Radiance
30. Divine Mastery
Yes, Staff Fighting was definitely something I was looking into for the AC boost but didn't know if I could afford to squeeze in. Are there any smarter/more optimal choices I can be making with this feat selection?
Mark of Healing is a must for just about any cleric. Radiant Vessel is nice, but the deeper you go into paragon, the more you'll want those extra saving throws from MoH.
If you're interested in maxing out your Channel Divinity power, consider taking Gambler's Word (gain extra use of Healing Word when you crit, once per encounter) and acquiring a Champion's Hauberk (spend one healing word to gain extra use of Channel Divinity, once per encounter). Pick up a nice extra CD like Power of Amaunator, and don't forget to take the Reverent Mettle utility 10 power (recharges whenever you use a CD).
Power of the Sun is a nice addition to the radiant vulnerability portfolio if you have a spare feat.
Consider swapping out Versatile Expertise for Staff Expertise, which lets you use your staff as a weapon and an implement, increases your melee reach by 1, and eliminates provoking OAs when you use ranged or area powers. Holy Nimbus symbol is nice, but there are so many ways to boost your healing that you're better off consolidating into one weapliment and picking up a +2 Symbol of Divinity, which gives you an extra action point on a crit once per day but which doesn't actually need to be wielded (i.e. you buy the level 9 version and never have to upgrade it).
Folks here will probably disagree with me on the following, but if you're MCing Invoker, you might want to replace swapping out your level 7 power for the awesome Rain of Blood power (area burst 1, gives vulnerable 5 to all targets on a hit) using the Novice Power feat.
I would support sticking with accurate superior implements, instead of astral implements. Hitting is nice, and that +1 makes a difference.
Lastly, you have Invoker Implement Expertise in paragon, but it's an epic feat, so you can't take it in Paragon.
Hope that helps!
