This is the idea I've been tossing around..
Point Cost: 175/190
AV 13 F 13 S 12 R
Wargear: 2 Dreadnought CCW w/ Builtin Storm Bolter
Wargear choices can be taken from Dreadnought or Ironclad Dreadnought option list.
Chapter Relic: The Marine spared from death by being encased in the Sarcophagus is a Marine of extraordinary renown and valor, beyond that of those serving beyond death. Fighting along side of this fallen hero inspires those around him. Any Space Marine unit within 6" gains Feels No Pain.

If the 190 points are spent, the following Special Rule also Applies:
Relic Plating: The plating equipped on the Dreadnought has been specially tempered to be resistant to extreme heat. Melta Weapons, instead of gaining +2D6 for Armor Penetration, instead gain 1D6 + 1D3.
