Buddy and I were spitballing and this is what we came up with. We aren’t super deep in the lore so apologies in advance.
Rogue Trader and Skitarii.
Rogue Trader would act as a support, being able to creat pockets of breathing room while providing hefty supplmental damage.
Lore wise, the RT could have been double crossed by a Governor, maybe even by the one of Atoma. Imprisoned for bringing the governor some of their preferred libations because they didnt want to pay.
Weapons would be similar to the veteran, with their signature ones covering some of the other we havent quite seen yet. Power axe, bolt pistol, and plasma pistol for instance.
Blitzs we figured a servo skull that fly in the direction you’re facing, taunts enemies as it goes by (maybe 2 seconds) then explodes, either as a firebomb or normal explosion.
Second blitz would be a replusor field/shield of some kind. It wouldnt block ranged attacks but could hold/divert enemies (except elites, unyielding, monstrosities).
Third blitz option would be Overtuned Weapons (Ranged option) or Adrenal/Stim Rush (Melee). Overtuned weapons would be able to briefly penetrate enemies and armor (even bulwark shields) A/S Rush would have a higher attack speed and reduced heavy attack charge time.
Skitarii. Lore for them to be introduced would be tricky other than Hadron became so testy with a failed squad (and with Grendyls authorization) she decided to construct versions of the Mechanicus’ rank and file. However, since she wouldnt have the best materials to work with, she made do with something semi unstable but would do better than the “Varlets” she deals with.
Skitarii would a bit more unique in the aspect that each tree could be based on (or least versions of) the Vanguard, Ranger, Rustwalker/Infiltrator. On top of that, they have to manage their power levels otherwise they will shutdown and need a manual restart.
Vanguards Blitz could be a frontal blast of energy/radiation that causes bleeding (think psyker scream but a little more oomph) but uses a good chunk of their energy and needs a recycle time.
Ranger Blitz would finally give the players something similar to the snipers we fight. But better. Would fire a narrow, concentrated beam with heavy penetration. Or an iption would greatly reduce the penetration in favor of a scatter blast. Again, uses a good chunk of energy and recycle.
Rustwalker/Infiltrator would fill the ‘undying berserker’ role. Energy is used to greatly empower all melee attacks, increasing melee attack and movement speed, damage done, and increasing damage resistance. Each attack drains small amounts of energy, more so with heavy attacks. However the buffs are relative to energy, so the lower your energy, the lower the buffs. Options would be better energy consumption (or greater buffs) or the Infiltrator version where youre able to attack while stealthed until ability is turned off. Also would use even more power.
Initial weapons selection would be akin to the zealot, though far fewer options. That would be offset with a higher selection of signature weapons. The signature weapons including Galvanic Rifle and arc weapons (Radium weapons would be too hazardous i would think. Or some sort of versions at least.
Did think of another idea for a dropped consumable (also an obvious one), sentry turret. Couldnt find anything smaller than the tarantula type, so no idea if any do exist.
As i said, these were just ideas and simply felt they needed to be shared with the community.
