Wonder is good, challenge all good. Uniform looks fine to me though you may want to call out specifically where the appropriate colors from the Castor Knight swatch will go - and if you and your artist want to work something more out with the design specs that's A-OK too!
Weapon progression is logical and neat-o (I looove the Sphinx gauntlet, btw).
My biggest concern here is his magic. I feel either there is some clarification needed, or an alternate choice in execution. Unlike senshi, knights don't have casting numbers - their magic lasts as long as they want it to last. They have their 'pool' of magic (the length of time their casting can last at maximum) and they can decide however they want to split it up: if Halicarnassus wanted to knock Aue back for 12 seconds and Tiberius back for 5, he would have used a total of 17 second from his magic pool.
TL;DR on the magic pool is this: Knights can use their magic until they've used up all their 'time'[magic].
For an offensive magic like the knockback, he would have a 25 second pool at squire and a 45 second pool at Knight.
If you wanted to change the magic, I have a suggestion that involves playing around with gravitational forces quite a bit using the gauntlet. Same weapon progression, and at squire he can activate a gravitational field on a selected target that immobilizes them (with the severity based upon opponent rank vs Halicarnassus' rank) and can - if the player wishes it - effect crush damage for flavor text a la
this lovely example here.
As it is offensive magic, it would be appropriate for him to be able to cast for a total of 20 seconds at squire and 40 seconds at knight.
I hope that my critique is helpful in completing Knighto's profile for stamping! The suggestions I made are just that - suggestions - and you do not have to take them; however, the issues I noted will need to be corrected before he can be stamped properly.
Please let me know if you have any further questions, comments, or concerns and I will do my best to work with you to address them. Feel free to quote me when you're ready and I will come back by!
