Bonus evaluation Edit
+3 to initial Perception Edit
Perception attribute influences PC's visible range, as well as improves searching abilities (easier detection of hidden doors, possibly traps). Overall, it is not extremely important, but provides advantage for certain aspects, such as ranged combat, etc.
+3 to initial Willpower Edit
Food is more nutritious for you Edit
Food in ADOM typically stops being a serious issue by the time the PC reaches the Arena. The Wolf bonus is still very good, saving both time and money, as well as reducing the chance to face hunger problems in a middle of a serious fight. Drakeling characters, relying on their acid spit ability, can benefit from this bonus, while Troll adventurers will experience less difficulty in managing their increased food requirements.
Wolf doesn't provide very powerful bonuses, but is a solid choice for players who often experience food problems. A boost to Perception may increase PC's visible range allowing for more flexible tactical analysis of game situation, as well as increasing the efficiency of ranged combat. All in all, a solid choice for novice players.
