6 - is he a summon or a companion? can i have summons beside him working?
7 - do feats like augment summonig and beckon the frozen work on him??
8 - does he block the ability of Thaumaturge to have the cohort active? can we have him + summon and cohort active?
9 - if he is small version - does he have the benefits like halfilngs and gnomes for being small? +1 size bonus to Armor Class, a +1 size bonus on attack rolls - if so does it affect his base dmg at 23HD level?
