Land's Graviton Raider, 480 points.
AV14/14/14, 4HP, BS5
Gravitic Flare Shield
Grav-backwash (only a-1 to hit this time, too heavy and big, but only works stationary)
Explorator Adaptation
Reinforced Structure (6++)
Primogenitor Supernum
Master Explorator Array
Quad-volkite turret with thermo-targeters (S6 AP4 Deflagrate Heavy 8, twin-linked)
Thermo-targeters:
A very helpful device for Archaotech scouting, it also finds an excellent use in battle. If a unit has taken wounds from Volkite or Phosphex weapons, including as a result of the Crawling Fire or Deflagrate special rules, the quad-volkite gains AP3 against that unit for the duration of the game.
Primogenitor Supernum:
First and greatest of the Raiders, this vehicle is immune to the Melta and Lance special rules, and reduces the extra D6 granted by Armourbane to a D3. Anything that would cause an automatic pen causes a glance instead.
Gravitic Flare Shield:
Normal Flare, but instead of a-2 to Blasts it can be extended to the side armour if the vehicle is stationary (Inc. pivoting).
Transport cap 12
Master Explorator Array:
Reroll on Reserves, all scoring units now contest or control objectives within 5" instead of 3, and all vehicles gain IWND, like an Archimandrite.
Can select D3 units within 12" after deployment to gain either Twin-linked, Monster Hunter, Tank Hunter or Enhanced Targeting while Land is alive, all must have the same rule.
Taghmata or Reductor LoW.
Counts as an Archmagos, and is automatically Warlord, Primarch style, but has no Warlord Trait as it's included in the package anyway.
What do you think?
Big unkillable brick with buffs, but he has to be still to survive best, and doesn't have much firepower on it's own.
Buffs are huge, but it lacks firepower itself, so if you shoot the things around it it's reduced to bullying tactical squads every couple turns. Unlike Primarchs, it can't just lol through anything it reaches, so it buffs damn well.
