Rubick, the Grand Magus

[Minato Namikaze]

Your History, which includes the Prologue, still doesn't tell us HOW and WHEN he came to the Omniverse, it just gives us a description of events that happened before he came to the Omniverse. I would suggest taking a look at other Join apps and what they did with their character's histories.

Staff of the Magus - Seems good. I mean, you don't really need that part about the staff shattering, because Omniphysics balances all. But it's fine as is.

Arcane Bolt - This is fine, but it's price is 600, not 300

Hidden Daggers - Looks good.

Nulling Field - The shield can last for the full 5 minutes without getting weaker. But this will be ineffective against super moves, they have their own mechanics and will just break though this and do full damage.

You're leaving it very vague, in terms of what the shield can and can't take. Normal punched and hits from swords etc. will effect this. It needs to be mentioned how many hits the shield can take.

I will say that one, charged, attack would break the shield or at least bring it to the point of breaking if hit by a relatively weak attack or projectile. But as for normal attacks with fists/ swords and bows etc. I would say that it could take a fair few, but within reason.

You can't have the shield constantly blocking attacks like this through out a fight and forcing an enemy to use their stronger moves that they may be saving as a surprise or final attack.
