Colosseum 2 is currently the hardest dungeon available in the game as it features truly outrageous spawns along with all cards starting at level 1 in a rogue-style dungeon.
This means that higher Team Cost cards will level up more slowly along with Super Awakenings being disabled until the card reaches level 100 or higher. This can place numerous hurdles for Team Building and can make it difficult for Transforming teams to function as it will be harder to have sufficient Skill Boosts.
As a whole, I do not feel it is worth playing Colosseum 2 due to the significant difficulty jump from Alt. Arena 3 (AA3) and mediocre rewards. While the Latent TAMADRA (Extra Slot) drop is nice, GungHo has given out many of them for free (maybe 13 so far?) along with few viable spots to take advantage of them.
Regardless, I wish to explore how I built my own team along with addressing the major hurdles that can be found in Colosseum 2.
