Here is my charsheet, HP not added yet as it's remains as question still.http://www.myth-weavers.com/sheetview.php?sheetid=296337
I am using the Dragonscale Husk feature from Dragon magic. It gives me ability grow scales which AC value is 6 + 1/3 class level which gives it (this case knight gives it). In 5th level I receive resistance 5 vs Acid, Cold, Ligthning and Fire. It grows over the levels. Bad side this armor cannot be enchanted with item creation feats nor increased with magic vestment potions. But at 18th level it gives me +12 AC which is same as Full Plate with +4 enchant. It's perks is that I can shed armor off in 10 minutes but it takes 8 hours grow back. Also I can sleep that armor on without any penalties.
Also in 5th paladin level plan take Drakkensteed mount and plan focus and expand on mounted combat after that point then. But otherwise I am well rounded face guy; +8 sense motive, diplomacy and intimidate. Bit religion and nobility lore. Build wise I am tank, the shield ward gives me shield bonus to touch AC and affects to resist trip, bullrush, disarms and grapple attempts etc. Divine Shield is from Complete Warrior and allows use one turn undead charge to get Charisma mod to my shield bonus for egual to 1/2 char level in rounds. So I am sitting at 28 AC vs everyone and 29 AC vs single target (+5 vs ranged attacks).
Altough damage potential is not that great with my knight but if he uses Test of Mettle and forces lots mobs charge him....he gets AoO vs any foes who charge him and he can strike three foes before they strike
. Also knigth challenge gives +1 to hit and dmg and will saves (increases to +2 in next level). If he stands adjacent to anyone he can take hit and half dmg.
