Idea for a cleric kit, Sikret - take a look Options

[Kraitok]

I had an idea for a cleric kit that I thought would be interesting. I had a couple of key points in trying to make it beneficial, unique - especially in comparison to the other Cleric kits, but also unique from a Paladin. Furthermore, I wanted there to be opportunities to for quest idea's and lines out of it from a roleplaying perspective. This puts them as beefier than true clerics, although probably worse than a dual r/c or b/c. What are your thoughts?

Heretic - Cleric Kit

Background
===================================
Heretics are the cast out and unbelieving among the divine orders. Beyond simply not having an affity with a Deity, they tend to incite anger among the Deity's followers simply by virtue of thier own chaotic nature. While it's virtually unheard of that a God would venture into the mortal realm to deal with them, neither do they bestow a Heretic with thier blessings. While they are still powerful Clerics in thier own regard, the lack of connection to the divine has it's drawbacks. Disconnected and often hunted by thier past church, they tend to be resourceful and hardy individuals who survive on the run. Indeed, survival seems to be the one thing all true heretics have in common. As such, they benefit from a number of immunities and and prefer to use a shield in combat.

Advantages
===================================
Granted -1 to AC Bonus at levels 1, 7, and 13 for a cumulative -3 AC bonus (possibly -4 at 19?)
+1 Bonus to Saving throws at levels 8 and 16 (8, 12, and 16?)
Gains an additional 1/2 attack per round at levels 5, 10 and 15 (9 & 15?)
Immune to Charm, Hold, Confusion, Fear, and Stun

Disadvantages
===================================
- Cannot Dual-Class
- Suffer a -2 Penalty to Charisma
- Suffer a +1 penalty to casting speed (debating this)
- May not Turn Undead
- Must be of Chaotic Good or Chaotic Evil alignment
- Do not recieve a magical ring from thier Deity at 25th level
- May not specialize in Dual Weilding, Single Weapon Fighting, or Two Weapon Fighting
- Require 13 Intelligence
- (protagonist only - no cleric stronghold)


Keep in mind, I don't have any programming experience, just a couple idea's.

Emphasis on a shield may be a good idea. Maybe they have sword/shield style as bonus proficiency, the same way rangers start with two weapon fighting?

Fighter saving throws are worse than cleric's at low to mid levels, but later, they surpass clerics in most areas except save vs death, in which clerics remain supreme. So a heretic does not have any God's favour at the start of his career, so starts off with worse saves than a cleric, but as he progresses he becomes exceptionally tough, relying on his skill more than any cleric who would first trust his God, he will have better saving throws at the high end levels. I think it makes sense.
