>>Once per post you can cast a 2nd level or lower Earth spell without it counting towards your spells per post. You cannot use this to cast more than two spells in a post, even if you have other abilities that let you cast extra spells (e.g. If you have both Storm Called and Earth Bound you can't cast a spell, a bonus storm spell, and a bonus earth spell in the same post because 3 > 2).
>>The size/volume/etc your earth spells with limitations measured in feet is increased by 50%. For example, the maximum length of your stoneblade spell would be 6' instead of 4' and your sandstorm spell would have a 75' radius instead of 50'.
>>It takes far less effort than normal for you to learn earth magic - you need only spend 30g per spell level to learn new earth spells.

Lvl 4. Your hair and nails become razor sharp and metallic.
Lvl 5. Your bones become metal and much harder to break, as well as channeling electricity harmlessly through you.
Lvl 6. Your body's rigidity prevents outside forces from influencing it. You gain immunity to outside magics that would directly alter your body and your connection to the earth means you cannot be moved if you do not wish it.
Lvl 7. Your skin becomes living stone and you grow a foot taller.
Lvl 8. Choose any one simple or basic art rune. Thrice per encounter you can cause the chosen rune to appear all over your body, granting you the benefit of the rune as though you were an enchanted object for a single post. Some rune choices might not be possible and/or sane. You can change the chosen rune whenever you learn a new earth spell.
Lvl 9. Twice per encounter you can root yourself to the ground and turn yourself into a true monolith of immobile, unmovable, indestructible stone, completely aware but incapable of movement. Can only last for three posts.
Lvl 10. You learn to harness your attunement for a custom ability based on your personality and earth.

>> Miner Retinue - Nathaniel can, with 10 minutes of focus, summon a group of 8 intangible, nearly transparent miners armed with picks and shovels. The silent miners can only interact with unattended earthen materials, are of Strong strength, and disperse if anything forcefully strikes them. The miner spirits work diligently and can follow complex and/or vague instructions, but refuse to use their skills for anything other than construction. The spirits cannot move farther than 50' from Nathaniel and take 2 summon slots to maintain.
>> The King's Call - Whenever Nathaniel achieves a new, even level of Monolith (2,4,6,8,10) he gains access to additional kinds craftsman spirits that he may summon in any combination whenever he summons his retinue. All craftsman spirits refuse to use their skills for anything other than construction. Furthermore, the maximum number of spirits Nathaniel may summon and maintain at the same time increases by four whenever he gains an odd level in Monolith.
>>> Level 0 - Miners - As above. The miners can also utilize any non-magical, mining-related skills Nathaniel possesses. (4 Spirits)
>>> Level 1 - Enhanced Retinue (8 Spirits)
>>> Level 2 - Apprentice Masons - Ghostly masons capable of more advanced, if novice, construction work. They posses all of the tools needed to work soil, stone, and mortar (should any suitable material be available). The masons can also utilize any non-magical, masonry-related skills Nathaniel possesses. (8 Spirits) [2 Minors]

>> Aspect Devotion - The powers of the Pick of the Mountain may only be activated by a wielder in possession of an Earth Aspect, whether or not they are aware of their own powers.
>> Earth Resonance - The pick can be used as a conduit for Earth spells as though it were a limb.
[del]>> Mineral Binding - The pick can powerfully cling to any earthen material it has been driven into until the wielder desires otherwise. The clinging effect is of Mighty strength.[/del] (unnecessary with his incredible strength)
>> Devour Earth - Upon striking an unattended, non-magical stone or earthen surface, the pick can be willed to absorb up to 10 cubic feet of material. The area effected can be any rough shape within a maximum range of 10'. Up to 1000 cubic feet worth of material can be stored within the pick in this way. Absorbing material in this way takes a spell per post.
>> Mountain Formation - With 30 minutes of concentration the material stored within the pick can be released and roughly shaped within a 20' radius, taking the form of a nearly invisible brown fog that solidifies over time. Material released this way remains attuned to the pick for 12 hours, allowing up to 100 cubic feet of it to be re-absorbed by the pick with each strike instead of 10.
>>Pick Focus - Nathaniel has heavily specialized in the use of picks - his current martial stances and techniques training do not apply to more general weapon use outside of wielding pick-like weapons and unarmed combat, and expanding his training to include such weapons would be similar to learning the technique from scratch (100gp but only the BP needed is halved).
