Mauler Familiar Archetype question

[Dysfunction]

The Mauler Familiar limits the familiar's Int as per below:

Familiar Folio wrote:

Increased Strength (Ex): At 3rd level and every 2 levels thereafter, a mauler’s Strength score increases by 1. As a result

of this ability, the familiar’s Intelligence score remains 6; a
mauler can never have an Intelligence score higher than 6.

what happens if it uses a headband of intellect - would it have a 6+2=8 or would it be 6+2=6?

[QuidEst]

"Can never have an Intelligence score higher than 6" is really clear. Headbands of Int are wasted on them.

[Dysfunction]

I guess my question is regarding if enhancement bonuses or temporary increases from spells would be limited by the Archetype.

in other words, is this limitation written to cap the Int increase that familiar's gain for being bonded or is this cap intended as a global cap for everything

[UndeadMitch]

Global cap at six.

[Chess Pwn]

Nothing can boost it above 6. No temp, inherent, profane, enhancement, etc. Global cap for everything.
