Now that the game has been released, those with the Deluxe Edition of The Old Republic get a Training Droid pet and those with the Collector's Edition additionally get a Mouse Droid. How do these pets work? In particular, I'm wondering:
- Is there a limit to the number of pets you can have?
- Can they be upgraded or leveled up?
- Are there others besides the Training Droid that join in combat?
I'm also assuming they're more like items and don't have "feelings" like companions; do correct me if I'm wrong.
