All Dragon fun with mostly heavy pick

Intro:

This build is all about that new heavy pick Oblivium Mattock from the quest The Price of an Egg in the Terror of Demogorgon expantion.

This build was a not suppose to be too serious... But with its Strength base to take advantage of the Master of Forms Fire stance crit on a 19-20 +1 crit multi going the build is going to a wooping 19-20 x10 crit multi in endgame!
The build has some spellcasting but its gonna be hard to get the DC's up so its not the main source of damage but rather there for debuffs and later the 25% chance to paralyze with no save from Draconic Incarnation: Daunting Roar.

Class spilt:

You can go for 15DD 5DL instead for 5% move movement speed and an additional spell, but you lose the following:
+1 Imbue Dice, +5 Melee and Ranged Power, +3 to Critical Confirmation and Critical Hit Damage. The bonus of each of your Draconic Auras is increased by 1. and 1 feat, in this case Offhand versitality.

Skills:

Balance for Single Weapon fighting and recovery from being tripped.

Concentration for ki pool and ki regen.
Jump for ease of vertical movement.

Spellcraft for additional spell power

Tumble for fun.

UMD for scrolls.

Spells:

The spell list below is just nice picks, but Gust of Wind is a utility pick for niche spell effect clear, like fog, cloud kill, ottos danceing sphere etc. etc.

Additional info:

Race is optional but if you have enough additional racial points you could aim of the Durergar's weapon training IV(Pick and hammer training) for the additional crit threat range to make the the crits come more often, the additional 5%Quailty bonus to maximum hitpoints from child of the mountin and Forgemaster so your weapon dont take damage and counts and a spell casting implement.
Allignment must be any lawful in order to take the Dragon Disciple levels.

The racial and universal tomes are nice to have, but if you dont have them remove the points from the racial tree and vistani tree accordingly.
