Is it true that the Player's Guide does not come with the stats for the Beastform cards from Winds of Magic, or am I missing something?

How could I create an Amber Wizard in WFRP Lite using any spell with beastform?

Just looking at my Player's Guide and could not find the Amber Beastform cards in it. So yup, sounds like you need to by that boxed set to get the content. It has Amber order spells, but not the cards.

I'm not a "lite" gamer myself, our table uses cards etc., so can't offer much advice on what to do, sorry.

Here's the statistical info that should have been included in the errata for the player's guide:

There are 3 cards: bear, wolf and raven/crow. This is basic info strength, toughness, agility and any white bonus dice.
Green side
bear s-5,t-5+2w,a-3,trained athletics, intimidate, double resilience; dr5, sk3, def2
wolf s4, t3,a4+1w trained athletics, coordination, stealth; dr4, sk2, def 1
raven s1+2w,t1+1w,a1 trained coordination double skullduggery; dr3, sk1, def 1
Red side
bear s6+1w,T5+2w,a3, trained double athletics, intimidate, weapon skill. dr6, soak 2, def1
wolf s4+1,t4,a3+2, trained athletics, resilience, weapon skill; dr5, soak 1, def1
crow s1+1w,t3,a5+1w, trained coordinatin, double stealth; dr3, soak0, def2

If you create any new animal types, please let us know I'm not certain why anyone would ever play the wolf over the black bear, except that the bear cannot do skullduggery..

Wolf is rank 1 while bear is 3... little rule a big difference.

Thank you, Emirikol.

I'm the one playing the Amber Order Initiate in the Patrelcu's game.

If we try to create any new animal forms (tempting... but challenging), we'll certainly discuss the result in the foruns.
