Creature Create is freakishly addictive. Discuss its awesomeness.
So far, the Ruminants (Nashorn, Quattro-Horn) have been a pleasant surprise. They may be M-sized, but they make for quite capable physical attackers. Skewer ignores defense and you can set them up to only use it and nothing else. Though Quattro-Horn also has Quick Hit which is nice as well.
Boris is definitely one of the best Large monsters I've caught so far. Just by the fact that his basic attack hits twice, his general damage output is already leagues ahead of others'. I think I'll keep him round for a while.
Using L monsters with the White Mage dressphere, beating the first four tournaments was no problem. Though Shady Duo and Tonberry the Ripper are nightmarish and basically a brick wall to prevent you from unlocking anything else for now...
