Isn't a club a light weapon? Lightning club explicitely counts as a mwk club.
If it Isn't, i'll change it to light maces, it's the same.
the weapon is exotic, but i donxt think it's much of a stretch to only give the -2/-2 penalty for TwFing.
Also, weapon focus only gives +1 on attack rolls, not damage rolls.
And, to chrisrawr, thank you very much for your kind words, it's our first attempt at this and it means a lot. thanks. (also yeah, mistake on the armor thing. corrected now)
