Great write up, sounds like a pretty fun list to rock at 1k! I would point out however, that when using Destiny Dice for any of the allowed rolls, you use the number of Destiny Dice needed to complete the roll. So for casting spells or rolling for charges, because the "roll" itself consists of two dice, you must use 2 Destiny Dice to replace the "entire roll", not just half of the roll. I also don't believe the Destiny Dice can be used to determine the amount of random attacks a weapon gets, only the damage amount that the weapon can do, whether its d3 or d6, etc.
Anyways, thanks for the great write up! Going to be running Pyrofane mostly as well with the big Kairic blocks and shooting LoC so I'm always interested in seeing how it fairs for others! Good luck with your Guild list too!
