Earth

A slightly heavier strike than the other damage elements, plus a roll to stun. A stunned enemy loses its turn outright, so the value compounds: every stun is damage you do not take and a turn you gain. Earth's stun chance climbs higher with investment than any other element's headline number.

Earth is the one element that resolves its control off a dedicated stun chance rather than proc, so the tree's proc nodes are redirected into stun rather than being dead. Power still scales the strike.

Fights you are not confident about. Stun is the only pet effect that is worth more the closer a fight is, which makes earth the safest general-purpose pick.
