Werebear and extra attack

[Eslin]

It seems I can make two claw attacks even without extra attack, which is nifty. But with the extra attack feature, can I make two bite attacks?

[Yorrin]

Nope. A creature's multi-attack is not their basic attack by definition. When using iterative attacks you must use a basic attack.

That's not what he asked; he asked whether or not he could use the Extra Attack feature to make a bite attack twice.
