Hi. I find the description of the earth focus element a little anti-climactic at the end. Might I suggest an edit on the last part.
“Many of the fey races are especially adept at harnessing earth elemental mana, which is concentrated in the land itself. Imbue yourself with the essence of an earth summoner and win battles in the arena to perfect your mastery of the unpredictable and dangerous force of nature itself.”
