That's true, yet since your doggie is a MAGUS character he's not dealing much with physical damage (ATK), but magic (MAGIC) stat...
Since you asking for an advice: If I were you I would drop the sorcery talismans, and change them for those giving some HP (HP means HitPoints = life of your character) It's always to have more HP than less...
Your dogie has high MR (Magic Resist) stats so why not try to build something around it? For example try with 2 Ivory Power talis to get MR+15% and then you could be using 2 Paladin's Arcane to have MAGIC+20% of MR... The remain 2 slots I would fill with 2 Health Talis (Ward) to get +15% HP and gain some MAGIC and MR too...
Cheers,
