On Beowulf:
-STR/END/AGI all to B. In Parenthesis next to all his stats though, you can put the stats he has with Mad Enhancement on, so it'd be like "Strength: B (A)", "Luck: D (C)", and so on.
Weapon: As a Berserker, Beowulf carries only a single weapon: the magical giants' sword with which he slayed Grendel's mother. It was the only sword which held true in combat, without breaking or failing to damage its target. It was reduced to a hilt by Grendel's acidic blood when Beowulf beheaded him with it, but the Grail sought to restore it to its rightful glory when Beowulf was summoned. As a weapon made for and used by giants, the sword is utterly massive (an approximate equivalent would be Berserker's ax-sword in F/SN).
So, that'd probably be a Noble Phantasm so he wouldn't get that, but you can still make his weapon a giant sword, it just won't be the Giant-crafted one. Also, this is less important, but the Grail doesn't restore anything. Heroic Spirit Beowulf has all of his stuff, the Heroic Spirit is basically you in life at your prime with all your stuff. Servant Beowulf is just a half-rate copy of Heroic Spirit Beowulf, so it's not the Grail's doing, but if he was Saber or something he could still have the sword.
Charisma will be functionally sealed due to Mad Enhancement, since it can't be displayed, just so you know. You don't need to remove it or anything though.
NP range to 1, 1-2 is with a sword, so if it's his fists it'd be 1.
Description: Calling upon the sheer raw, unadulterated power that allowed him to tear Grendel's arm from his body despite the fact that not even swords could pierce the demon's skin, Beowulf tears his opponent in half with his bare hands. The attack can be blocked like any other, but rather than a single strike, Beowulf is capable of dragging this attack out over around two to three minutes, even while sustaining drastic damage during the attack. If he is able to disarm his opponent, his raw strength is capable of defeating almost any single enemy while this Phantasm is inactive. With it, he is unstoppable, and able to literally disarm his opponent.
Alrighty, so the first thing is that Grendel was explicitly made invulnerable to human weapons by the dragon, but not invulnerable to human fists, which is why Beowulf's whole "I'm gonna 1v1 him in punches" strategy worked out so well.
That said, when the NP is activated, what changes? What is the difference in his capabilities between when it's active and when it's not? I'm not quite getting that.
On Dalton:
-Please list the number of generations his family's been around for.
Origin and Elemental Affinity: Elements: Metal and Fire.
Metal's an element in Eastern Magecraft, not in Western. Same applies to Metal Magecraft.
Jewel Magecraft, though quite below the level of the Tohsaka family's efficiency or the Edefelt family's abundance.
Mystic Codes and Equipment: A single Jewel pendant that stores a significant amount of energy (about 15 times the amount of energy Dalton can hold).
You can't use Jewel Magecraft unless you have the Edelfelt's Conversion Attribute, which he probably shouldn't have.
Shared Perception and Transference of Consciousness.
Are you doing something different with these than is in General Magecraft?
Extreme proficiency in Reinforcement, Alteration and Projection.
Alteration's fine, but you'll only be able to add traits that you have the magecraft for, so since you have fire magecraft you can give a sword the alteration of being on fire, and then you have a fire sword, yay. Reinforcement, what's his proficiency level? Also remove Projection, it's rare and bad and weird.
Flowing and Transfer of Power.
This covers like, a lot of stuff. What under it does he know how to do? If it was just the Jewel Magecraft, you should remove it.
