Sensei, The NPC from Corperate Punishment Options

[Shockwave_IIc]

Ok, a Little background, in a one on one game i've just started the player is playing a mage for the first time. The basic background for the PC is that he's a third generation mage. IE, His grandfather is a mage and so was his father all of which were first borns and the only males by thier parents (Yeah your basic prophecy stuff though no Prophecy is involved).

Now the Grandfather (Nathen), is basically a mentor/ plot device for the PC (Nathenial). And after teh first session or so i thought it might be and idea the Stat Nathen if only basically, so i thought i'd use Sensei as a base. Now is it me or is Sensei a little weak??

Now the only things i know is that Nathen has a Sorcery of 8, and Willpower of 6 and the two spells his cast so far are Stun Bolt and Mana Static. Also is good enough with a "british Fencing Longsword"(If such a thing exsists) to soundly thrash the PC. Ideas on how to change/ Improve what i was wanting to use as my base??

Metamagics?? Spells? Foci? (over the Weapon Foci he already has)
