CHAPTER RELICS:
There are 6 different ones.
Two swords, one Bolter, set of armor, one Storm Shield and one banner
They range from 25pts to 65pts.
One Chapter Relic grants a 6+ Invulnerable Save. (It's unclear who benefits from the Save generated by the Relic)
Relics are not Chapter-specific.
NEW WEAPONS:
Grav weapons - Have the Concussive special rule, but are not Blast weapons.
Grav weapons wound the target based on their Armor Save. For example a terminator has a 2+ save so they would be wounded on a die roll of 2+. Against vehicles roll a die, 1-5 does nothing and on a 6 the vehicle is Immobilized and loses a Hull Point.
