Earthen Fury's description (the Enkindle ability of Titan-Egi) in English completely omits the potency of the damage over time effect.

Deals earth damage with a potency of 200 to all nearby targets.
Additional Effect: Razed Earth
Duration: 15s
Executed when master uses Enkindle.
自身の周囲の敵に土属性範囲魔法攻撃
威力：200
追加効果：ダメージエリアを生成する。
威力：20
効果時間：15秒
マスターが「エンキンドル」を実行することで使用する。
As you can see, the Japanese description states a potency of 20 damage over time, while the English description simply states "Razed Earth."

It's been this way for a while, and I noticed it a while ago, but I guess it never got fixed. Finally decided to post here, hopefully that will help.
