Name: Magma Release
Type: Advanced Element
Requirements: Katon (S) || Doton (B)
Ability Tier: 3
Minimum Rank: Special Jounin (B)
Description: By focusing the power of fire and earth together in proper amounts, the user is able to melt the solid earth into liquid magma. The viscosity(liquid thickness) of the magma depends on how much fire chakra is added to the base doton amount. Suiton or Doton jutsu of equal or higher rank do damage equal to 1 rank higher than normal (cap at SS); while suiton of lower rank deliver zero damage. This release is separate from the clan based Kekkei Tota in that it is far less complex, and there is less control overall of what the magma is able to do. This version caters towards large volumes of magma being created over large areas, versus the pinpoint control and accuracy of the Lava Release; as well as not granting access to any of the other 2 forms of release that Lava's KKT allows for.
Unlock Requirements: Katon trained to S-Rank. Doton trained to B-Rank. Must undertake 2000 words additional training to unlock to D-Rank.
Special Training Requirements: All Magma jutsu require additional 500 words to train.

I'd just add a little note in the description that tells the difference between this and Lava Release, similar to what you did with Plant Release. Other than that, it looks great!
