Heretic megawad (new) weapon designs

[Coolangel333]

Hey Guys,
it's been a long time, but i'm currently trying to create a heretic-hexen megawad, inspired from Hexen: resurrection and Heretic: Faithless trilogy. I've planned a few new weapons, and I've browsed realm667 to find the foundations of weapon, that I can modify to my liking. Two of the new weapons i'll add will be a purple jadewand, and a frostfang but the powered up version will shoot a projectile similar to the wendigo (iceguyfx) in hexen.

I have plans to add the justifier (dsparils staff) as well, however i'd want the projectiles to be more effective, and more similar to tempest wand. The problem is, that I don't have the code for it, and I don't know how to even access it.

For the jadewand i've only recoloured and unsure how I should modify it, any recommendations?
