Ezren Mystic Divinier (core) -explore ability

[Rafał Kruczek]

Ezren Mystic Divinier (core) has ability( only relevant parts)
On your ( [] or any) turn you may recharge a spell to examine the top card [...] If you do you may discard card to explore."
So is this ability a way to explore out of turn? Or on other player's turn you can only examine?

[Brother Tyler]

PACG Core Set Rulebook wrote:

You may never explore outside of your explore step.

Key word: "never" (When the rulebook uses the word "never" or "always," nothing can override it.

So the power feat to explore would only be usable during Ezren's turn during the explore step.
