[@Crusader Lord] Well, let's see:

-Suitcases of Supplies: Include plenty of prepared magic bullets, money, clothes, a pair of subtly purchased Mystic Eye Killers from a certain mage for self-protection, packs of joints and lighters he added to it all, an advanced first aid kit, and other things generally needed to stay and get by day to day in an isolated place such as Black Rock for the duration of a Holy Grail War.

You don't need to mention general supplies. You don't need to remove this but it's redundant. I'm mentioning it more to clarify that to the other players sine they might think they should add this as well. I'm not going to pull a "You don't have it written in your CS, then you don't have it in the RP" as long as what you are doing makes sense. Things like Mystic Eyes Killers and Azoth Blades, reagents, etc. are commonplace Mystic Codes that most Magi will have hanging around at all times.

[i]Superior Mystic Code[/i] - Johann has two replicas of a Primeval Rune. [color=ed1c24][b]These runes, indestructible by magecraft, are able to amplify the curses of his other runes by tens of millions of times.[/b][/color] His family has given him these for use in the Holy Grail War, primarily to try to help keep him alive.

Not even the original Primordial Runes are indestructible, other wise they wouldn't need to be kept on a vault in the Wandering Sea to avoid degradation. Also, I hope the second part is hyperbole, again. Because this is beyond even the levels of the greatest Noble Phantasms.

Lastly, it would be helpful to know what kinds of curses he's specialized on since they aren't mentioned anywhere else in the CS.
