I really like a great assistant helping me out in some time, like a side-kick to rely on. I think it could be possible to easily add a mecha-bot like sidekick that goes with the knight at all times. The knight first has to purchase the bot from the bazaar (with cr or ce...that's not up to me) and activate it. Then knights can also buy gear for it. Since they only use swords, OOO could design new types of swords for the bots, maybe based on 3* swords. Knights could also purchase armor for the bot, just as they would for themselves. The knight also has to have health. It's like a regular knight, but when it dies, you can't have it until the next floor where it automatically revives.

I think this is a great idea. The programming could be drawn from friendly mecha-knights, and tweeked a little.

Please consider this :)
