M'Kraan Crystal (X-Men)

This One-Shot gives +2 to player side and an extra +4 to monster side.

So I'm confused on which is the bonus for monster side:

+4, because the base +2 is only for player side (normally the One-Shots' base bonus is "for either side", so there should be a reason to state differently)… but why it says that +4 is "extra", then?

+6, because it says that the +4 is *extra*, so +2+4... but why the base +2 is not "to either side", then?
