For those of you who have played Generation 1, what do you think of the Collaboration system introduced in that game?
If you haven't played that game, the system works like this. There's a shop in Camineet that sells crystals. Two crystals can be equipped to each character's weapon. The crystals are mostly elemental aligned (fire, ice, wind, etc) and allow the character to cast a spell through use of them. Some combinations of crystals allow the casting of special spells that are similar to PSIV's combination attacks (but with just one character). The crystals can break, which may be related to the character's natural spell casting ability, as I noticed the break more with Odin than Noah.
