Best talents in my opinion are far out man, all skilled up, pet pal, and mnemomic.

summon from further away (get the drop on a mob group by dropping an incarnate in their faces, saving you AP) bonus points into summoning earlier (Saves you some pain and gets the ball rolling faster) The most useful talent in the game out of combat (duh.) and who doesnt love free skill slots? Especially on a summoner.

Pure wolf build? You do realize that the wolf is kinda... bad... right? Stick to the incarnate, slug, and flower. Spider is only good for supercharge cycling, and bloated corpse is a fun party trick when paired with flaming crescendo. The cat, wolf, and condor all have their... purposes. But there are much better options. Dragonling and Inner Demon not mentioned due to spoiler purposes and because they (like the wolf) are character centric.
