how to build clever bird, and on which making it special? plz help

[aquarose]

i saw many int bird recently. and i wonder how it is built.

for the stats,
was all pts goes into int?
putting into dex does not rise dmg, rite?

im thinking. enough int for gear, and excess pts into dex, if dex actually increase magic wpn crit.


also, why int bird is workable, and incentives are?

plz contribute, as i know little abt this type of build, and would like to try it out.
