Mastered Elemental Bond: Earth

The bond with your elemental of the Earth grows, furthering your mastery of the element, enhancing your senses and physical prowess.

• Seismic Sense: You touch a solid surface, such as a wall or floor and cause tiny tremors to course through the surface and all connected solid matter within a 30ft sphere centred on the point you cast the spell. The tremors pass through any solid material within range, so long as it is connected or touching the surface on which you cast the spell. They are stopped by pockets of air or liquid, and cannot detect the presence of living organic material, including plants. You are also able to feel the comparative density of structures within the area, possibly discerning what material each is composed of. In this way, you are provided with a mental image of your immediate surroundings in all directions, including above and below you. The tremors are imperceptible to all creatures other than you, or to any creatures within range that have tremorsense, or which also has this ability. You may use this ability once, regaining the use when you complete a long rest. You may also use this ability expending a 3rd level spell slot or higher. If the spell slot you use is above 3rd level, the radius of the effect is increased by 5 feet for each spell slot level above 3rd.
• All melee weapons that have the heavy and/or two-handed traits, and do not have the reach trait, count as versatile for you. The damage die for such weapons remains the same, however, when you make an attack with an applicable weapon you are holding in two hands, you add 1d4 extra damage to the attack.
• Mastered Innate Spellcasting: You learn one of the following spells and may cast it once for free as if using a 3rd level spell slot, regaining the use when you complete a long rest: earth tremor, jump, longstrider, earthbind, find steed, Maximilian's earthen grasp, spike growth, erupting earth, meld into stone, wall of sand. Charisma is your spellcasting ability for this spell. You may swap this spell for a different one from this list when you gain a level.

If you select the spell jump or longstrider, it counts as having a range of self when cast using this feature.
If you select the spell spike growth, the spikes appear as jagged rocks, sharp crystal formations, or shards of tile jutting from the earth, and the spell fails if you attempt to cast it on a surface not made of earth, sand, stone or tile.
If you select the spell find steed, the summoned creature is considered to be an earth elemental, and appears to be made of rock, sand, crystal, or similar material. Otherwise, its statistics remain the same.
