Your natural talent has the following benefits:

You gain one of the following Leveled Talents: Monolith, Quakelord, Pet Rock. Your level in this talent is equal to the highest level Earth spell you know.
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.
You can learn the highest level spells (8+) of the earth art.

Lvl 3. Your sense of touch and hearing are merged together. This allows you to discern things about your environment that others would not, especially when it comes to movement or vibration. This sense allows you to tell what materials are in an area or item by tuning them with a light tap.
Lvl 4. You can control the vibrations in unattended, non-magical earthen materials and any such materials created or manipulated by your spells. This allows you to treat up to 30 cubic feet of such material within 30' as a held object for the purposes of your Quakelord abilities. You may use a spell per post to instead effect up to 1000 cubic feet of material.
Lvl 5. You may temporarily extend your vibration ability to larger areas of earthen material in the environment, causing them to match your own personal frequency. Twice per encounter you may use this ability to phase quickly through 10 feet of solid stone or 5 feet of solid metal. When this effect ends you ejected from the material at the nearest possible exit.
Lvl 6. Your ability to manipulate vibrations improves, allowing you to increase the effective modifier of earthen objects by another level and/or cause them to crack and/or explode into a cloud of dust and shrapnel on impact. Using this ability counts against your spells per post, larger items are less likely to explode.
Lvl 7. You may choose one additional solid material to consider earthen for the purposes of Quakelord abilities (e.g., wood, bone or glass).
Lvl 8. You may harmonize earthen objects with any others, allowing you to increase their modifier by another level and/or grant them the ability to pass through up to 3' worth of other non-magical earthen material. Items that would get stuck are shunted to the nearest available space. Using this ability counts against your spells per post.
Lvl 9. The power of your spells echo into the world around you. Whenever you cast a spell you may use one of your 8th level or lower Quakelord abilities without it counting against your spells per post.
Lvl 10. You develop a custom WM-approved vibration-based technique/ability.

Your natural talent has the following benefits:

You gain the following Leveled Talent: Shadowtwin. Your level in this talent is equal to the highest level umbral spell you know.
Whenever you use your spell per post to cast an umbral spell, you may simultaneously cast that spell twice instead. For example, you could cast blind on two different targets. Any other restrictions, like needed summon slots, do not change (you do not gain the ability to maintain more summons).
It takes far less effort than normal for you to learn umbral magic - you need only spend 30g per spell level to learn new umbral spells.
You can learn the highest level spells (8+) of the umbral art.

Lvl 4. Your shadow learns how to merge with the shadows of other creatures and objects. Merging in such a fashion gives the shadow knowledge of the physical capabilities of whatever is casting the shadow (strength, hardness, how good it is at jumping, if the door is locked, etc).
Lvl 5. You can store and retrieve non-living objects from your shadow while it is 2-dimensional, as though it were a portal to a space with 1000 cubic feet of space. Unattended objects can be slowly pulled/pushed into/out of the shadow.
Staff note: On death any such objects are ejected. If you were wondering.
Lvl 6. Your shadow can detach from a surface, gaining a third dimension and becoming partially solid as though a thick fog. It effectively has a strength level of Weak while in this state. It cannot be permanently harmed, but sufficient force will cause it revert to its two dimensional state and immediately flow back to its regular location. A forcibly reverted twin cannot use this ability again for the rest of the encounter. Your twin can otherwise switch between these forms once per post.
Lvl 7. You shadow can consume one of the objects stored within it, gaining power(s) based on what it consumed. If your shadow later consumes a different object the former gained power(s) are lost. Not all objects can be consumed.
Lvl 8. Once per encounter, while three dimensional, your shadow may further solidify into a being of jet black flesh. While so solidified the shadow’s strength rivals your own. If ‘fatally’ wounded the being reverts as normal.
Lvl 9. Your shadowtwin becomes capable of learning spells, warrior techniques, etc. It can cast a single spell per post, maintain a single summon, and can learn up to 4th level spells of any art. Your twin automatically knows/learns all 4th level or lower Umbral spells you can cast and benefits from any basic training (such as acrobatics) you possess. Any spells requiring physical motions can only be cast while the shadow is 3-dimensional.
Lvl 10. Your shadow gains a custom ability based on its personality and your true self.
