The description for every single one of the 12 Newborn Constellation Pets is virtually identical:

Quoted

Summoning Stone - Newborn XXXXXX Pet
Item Shop Item
Not dropped on PK death
Permanent Newborn Zodiac Pet summoning stone. Use it to summon Newborn XXXXXX Pet.

When summoning the Zodiac Pet in its Newborn stage for the first time that day, you will receive the effects of the Star Spirit Blessing: for 3 hours, increases XP and TP obtained in battle by 20% as well as item drop rate by 20%.

Is there any difference between the 12 Zodiac Signs, besides the appearance? If not then why should I bother getting more then one Constellation Pet regardless of its Zodiac sign?

Now I understand that the first time summoned you must make a choice between an XP or TP bonus that stays with the pet permanently. So it makes sense to have at least two Constellation Pets, one for XP and the other for TP. Is there any other reason/difference (besides vanity/bragging) for me to get additional newborn Constellation pets?

What about Adult and Legendary Stages?

Again the description is virtually identical for all 12 Zodiac signs:

Quoted

Summoning Stone - Adult XXXXXX Pet
Item Shop Item
Not dropped on PK death
Permanent Adult Zodiac Pet summoning stone. Use it to summon Adult XXXXXX Pet.

When summoning the Zodiac Pet in its Adult stage for the first time that day, you will receive the effect you previously chose when using this item for the first time. The effect will last 3 hours

The patch-notes indicate the following Options for Adult Constellation Pets:

• Increases item drop rate - 50% - Star Amulet of Fortune
  
• Increase XP gained in battle - 30% - Star Amulet of Rage
  
• Increases max. HP and MP - 5% - Star Amulet of Strength
  
• Increases TP gained in battle - 5% - Star Amulet of Talent
  
• Increases all attributes - 2% - Star Amulet of Ability
  
• Increases physical and magical defenses - 3% - Star Amulet of Defense
  

Quoted

Summoning Stone - Legendary XXXXXX Pet
Item Shop Item
Not dropped on PK death
Permanent Legendary Zodiac Pet summoning stone. Use it to summon Legendary XXXXXX Pet.

When summoning the Zodiac Pet in its Legendary stage for the first time that day, you will receive the effect you previously chose when using this item for the first time. The effect will last 3 hours.

The patch-notes indicate the following Options for Legendary Constellation Pets:

• Increases item drop rate - 75% - Star Amulet of Fortune
  
• Increases XP gained in battle - 40% - Star Amulet of Rage
  
• Increases max. HP and MP - 7% - Star Amulet of Strength
  
• Increases TP gained in battle - 10% - Star Amulet of Talent
  
• Increases all attributes - 3% - Star Amulet of Ability
  
• Increases physical and magical defenses - 5% - Star Amulet of Defense
  
• Increases physical and magical critical hit rate - +120 points - Star Amulet of Fortitude
  
• Increases XP and TP obtained by completing quests - 10% - Star Amulet of Potential
  
• Reduces damage dealt by other players - 10% - Star Amulet of Protection
  

Can anybody confirm that these additional Adult/Legendary buffs are available? Do you need to choose one of these and is that choice permanent? Are the Star Amulets mentioned in the patch-notes provided automatically or must additional tasks be completed?

The ONLY difference in the descriptions between Adult/Legendary is the substitution of the word Legendary for Adult. It would make sense if additional bonuses are available given the amount of time and AT-charges necessary to create Adult/Legendary pets. Regardless is there ANY difference between the 12 different Zodiac signs? Nothing definite can be determined from the descriptions.
