Hey Shan! I have a few things that I am uncomfortable with concerning Dravite, and my first concern is the length of his chain! I have gone through some of the negaverse agents and knights who have chains and have come to the conclusion that yours is far longer than any of the others that I have found.
Lt. Mesolite starts out with a paperclip chain which goes to a chain that is three feet, ending with a chain that is six feet. General
Natron has his general weapon in his art, and it is no longer than he is tall, so about six feet.
My own knight,
Whisler has a chain weapon, and it is only five feet long.
The lengths will need to be shortened for all three of your stages, and I would feel comfortable if the maximum length did not exceed eight feet.
Also for his general stage, since he has the magic, I would prefer that he not get a second item as the sword, and rather just had an increase in length of the chain and perhaps the dagger gets a little longer. The weapons should not separate, there is not nega that I have found that has two weapons that are so different from each other.
Please quote me when you have made changes!
