Divine Dragon,including Arcane Trickster.
I did this build in order to solo, I was looking for a very resistant character, good damages and polyvalent (direct attack and magic vs Fort, Ref, Will) in order to face all situations.
Attributes :
FOR 16 => 20
DEX 15 => 16
CON 14 => 16
INT 10 => 14
WIS 8 => 8
CHA 18 => 22
1 > Paladin 1 Weapon Focus (Natural Attack)
2 > Paladin 2
3 > Thug 1 Accomplished Sneak Attacker
4 > Scaled Fist 1 Dragon Style
5 > Sorcerer 1 Dazzling Display,
6 > Dragon Disciple 1
7 > Dragon Disciple 2 Power Attack, Dragon Ferocity
8 > Dragon Disciple 3
9 > Dragon Disciple 4 Shatter Defenses
10 > Dragon Disciple 5 Improved Initiative
11 > Dragon Disciple 6 Wings
12 > Dragon Disciple 7
13 > Dragon Disciple 8 Cornugon Smash
14 > Arcane Trickster 1
15 > Arcane Trickster 2 Metamagic (Extend)
16 > Arcane Trickster 3
17 > Arcane Trickster 4 Dodge
18 > Arcane Trickster 5
19 > Arcane Trickster 6 Metamagic (Quicken), Dreadful Carnage
20 > Sorcerer 2
At the end we have :
Paladin 2 => Divine Grace (add CHA to saves rolls), why not smite evil in some cases
Thug 1 => Sneak Attack and Intimidate (+1 round for Intimidate)
Scaled Fist 1 => Flurry of Blows, Stunning Fist, (AC Bonus CHA)
Sorcerer 2 with draconic bloodline (caster 14 for spells, draconic bloodline 10)
Dragon Disciple 8 => (+6 caster level, +8 Draconic Bloodline) +4 FOR, +2CON, +2INT, +3Natural Armor, Blindsense, Dragon Form 1/day
Arcane Trickster 6 => (+6 caster level) +3d6 sneak Attack, Impromptu Sneak Attack 2/days
Here is an overview 20th level including Item Boost (but not Dragonkind or spell boost)
FOR 26
DEX 22
CON 22
INT 20
WIS 14
CHA 28
BAB => 13 but get +4FOR so for me it is equivalent +15 and get additional attack due to Flurry of Blows
AC 51
Base 10
DEX +6
CHA +9
Dodge +1
Wings +3
Natural Armor +5
Bracers of Armor +5 (don’t know if +8 exist in game)
Sentinel Ring +2 AC Shield
Ring of protection +5
Natural Armor Necklace +5
Saves (close to auto save…)
Fort 19 + 6 + 5 = +30
Ref 16 + 6 + 5 = 27
Will 21 + 2 + 5 = 28
Sneak Attack +5d6 (Sense Vitals Spell can add +4d6 for +9d6 total)
Sorcerer Caster Level 14
Key Spells
7 > DragonKind II 4/days (3+1 due to high CHA)
4 > Invisibility (Greater)
3 > Haste
2 > Sense Vitals
For skills just some for Dragon Disciple and Arcane Trickster, then max Persuasion
Feats are Intimidation Oriented : Cornugon Smash and Dreadful Carnage provide free Intimidation test, Thug Intimidate make it longer, Shatter Defenses allow to sneak attack shaken enemies (those who failed Initimidation test) You can add Intimidating Prowess to increase the difficulty of intimidation test but it’s already very high.
The idea is of course to transform Dragonkind 2 and get 5 attacks (+1 with haste, +1 Flurry of Blows ?) wich can all sneak with +9d6.
If trouble you can quicken True Strike, Invisibility…
