Hey Skrittiblak, are you going to make stats for the Tau's armor or the drones that the Tau use? I can post the non d20 stats if you want.
Do not post any stats from Warhammer. Games Workshop gets EXTREMELY angry when people do this. They WILL get involved too. They have shut down many forums for doing such things in the past. Please share these stats with Skritti, or anyone else, over an IM system or through e-mail. Don't tease the hungry bear with a t-bone wrapped around your arm.
Thunder Hammers are one handed weapons though. They are intended to be utilized with another close combat weapon (bolt pistol) or a Storm Shield.
This is partially correct though not quite. Terminators can wield them in one hand with the storm shield in the other however everyone else has to use them with two hands. I think maybe power armoured people can use them one handed also not sure on that. Plus the thunderhammer is listed as a two handed weapon in the codexs.
Level Adjustment: +7
It has +28 to it's stats, Racial Bonus to Hit of +3 and Saves of +3 each. Gains two Bonus Feats, has natural weapons, special abilities, don't have to eat drink or sleep...
I'd say a +7 would be in keeping with that. MAYBE a +6, but then I'm not familiar with the rules of assigning level adjustments so I'll leave it up to Gunrock to do that for me.
Powerfists are 'light' weapons because they always form part of a powered-arm unit. They cover the targets entire armour and like powered armour are wired into the arm so they don't conflict with the arm's movement. Effectively they weigh nothing for the character.
Begads! I missed your post completely. I wasn't avoiding you. Promise!
Okay so why did I change damage.
I want a minimum amount of damage 'types' so we can handle things like resistances in a fairly generic way.
40k incorporates a number of different weapons and it would be silly to have a unique damage type ('flaying disinitigration' for necron weapons 'spinning shurikens' for Eldar catapults etc...) for each gun.
So here we go all firearms are:
PIERCING (weapons primary damage form is piercing - Stubgun, Autogun)
SLASHING (weapons fire slashing discs - Shuriken Catapult)
BLUDGEONING (weapons hammers you - Squat Thudd Gun)
ENERGY (weapon is laser based - Lasgun, Pulse Rifle, Hellgun, Needle Rifle)
ATOMIC (weapon is an advanced sci-fi energy type - Plasma Gun, Meltagun, Gauss Rifle, Dark Matter Gun)
EXPLOSIVE (weapons bullets explode - Boltgun, Missile Launcher)
True as that may be, for purposes of game balance they should really be one-handed.
Moreover since I've been using them for several years I've grown fond of these 6. In all honesty this is one of those things thats unlikely to change in future editions of d20-40k, so I hope I've done a decent job of justifying these damage types.
I have at least two replies to everything else you've said. This is the one arguement you've made in which I agree that your premise is true and that the form of your arguement is valid. As such I shall drop the discussion of damage types.
However, if you are interested in the responses I am willing to share them. If you are not, that's fine too.
