I need help advancing a ranger animal companion [3.5e]

[Rougy]

I'm creating my first character with animal companion and I don't know how to advance the companion. Well... my character have 18 lvls of ranger and I want a Winged Dire Boar.

Dire Boar, Monster Manual p 63
Winged Template, Savage Spieces p 138

thanks in advance...

You cannot have a winged direboar as an animal companion (unless there is some feat/ACF/houserule that you haven't mentioned).

Is a houserule.

You and the DM need to agree on how much of a penalty a winged dire boar will apply to your effective druid level. Once we can calculate your effective druid level, we just take the standard winged dire boar and apply the changes from the table in the druid class description in the phb.

As a side note, you won't get the higher level benefits, since ranger already takes a hit on the power of animal companion, and you are reducing it further by picking a stronger type of animal.

Beastmaster, 1 level. Boosts a Rangers animal companion quite well.
