I would have had an 18 Intelligence already ... and IMO I am simply NOT that smart.  You're undervaluing the impact of a high or low Intelligence score, if you want to tie IQ directly and sOLELY to that attribute (which IMO would be a mistake).Besides which, animals can have Intelligence scores of 1 or 2 ... by your measure, that'd put them at likely being able to understand LANGUAGE.Um ... do you know what a given IQ score means ... ?The normal IQ scale applies solely to children and adolescents (a different scale, using the same numbes, is used for adults).  An IQ score is literally a -percentage- value (originally my 142 would have been written as 1.42).  And it means, you responded to the tests in a manner consistent with an "Average" person that percent of your own age; that means at 12, I was answering questions as well as a (12 x 1.42 =) 17-year-old.  Academics and noncademics factored in, both.That's how it works.  Once you pass around age 20 or so, the scale shifts, and is no longer dependant on age ... but my most recent IQ test (in my mid-to-late 20's) still came out in the low 140's.  And I still don't think I have an 18 INT score.There is no direct correlation between a character's Intelligence score and their IQ.  IQ, more properly, should be based on an average of all THREE mental attributes, weighted slightly against charisma (you can be a real bastard and still score well on IQ tests, but human empathy and social adeptness -- measured in D&D with Charisma -- are factors in any decent, reputable IQ test).  If IQ is even calculated at all, which IMO is sheer folly, and a waste of time to boot....Try { [ 2 x ( INT + WIS ) ] + CHA } / 4 ... then multiply hte result by 10.  An average person (with 10's in all scores) gets a 100 IQ, as it should be.  Someone with Intelligence 14, Wisdom 12, Charisma 12 would get a 160 IQ:... { [ 2 x ( 14 + 12 ) ] + 12 } / 4 ... { [ 2 x ( 26 ) ] + 12 } / 4 ... {  52  + 12 } / 4 ... 64 / 4... 16... 16 x 10 = 160For 18 Intelligence, 14 Wisdom, and 14 Charisma ... we get an IQ of 145:... { [ 2 x ( 18 + 14 ) ] + 14 } / 4 ... { [ 2 x ( 32 ) ] + 14 } / 4 ... {  64  + 14 } / 4 ... 78 / 4... 14.5... 14.5 x 10 = 145For a "perfect 18" in all three attributes, we get an IQ of 225:... { [ 2 x ( 18 + 18 ) ] + 18 } / 4 ... { [ 2 x ( 36 ) ] + 18 } / 4 ... {  72  + 18 } / 4 ... 90 / 4 ... 22.5... 22.5 x 10 = 225And IMO, even then ... it's sheer foolishness to even bother calculating all that.  If you want IQ tied solely to Intelligence, try 8 IQ points per point of intelligence difference from 10 (11 INT is 108 IQ, 8 INT is 84 IQ, 15 INT is 140 IQ, etc).  I can see myself with a 15-ish Intelligence.  But not the INT(18) your table would indicate ... !![EDIT: Math errors ... *sigh* so much for that 18 Intelligence, eh? <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f631.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=":eek:" title="Eek!    :eek:"  data-smilie="9"data-shortname=":eek:" /> ]</blockquote>
