Editing Warhammer 40,000/8th Edition Tactics/Grey Knights (section)

===Relics of Titan===
Codices are adding back relics to armies. The way relics now work is that they replace an equivalent item, functionally free (though that still means you have to pay for the item it replaces, and the model needs to be able to use the equivalent in the first place).  The only two worthy of serious consideration is the Banner and the Cuirass; the first multiply your expected damage from Smite by more than 3.5, getting it up to Cleansing Flame levels at twice Cleansing Flame's range, and the latter will help keep you alive, including through Perils.  ''None'' buff your entire army, unlike the best choices from the Space Marines list, but both of those help your Smite output improve; a Brother-Captain in the Cuirass paired with a Paladin Ancient with the Banner will provide very pleasingly consistent Smite output the entire game.

*'''Banner of Refining Flame:''' Paladin Ancient or Brotherhood Ancient only. The model immediately loses the Rites of Banishment ability, and this time Smite drops to a pitiful 6" range, but always does D6 Mortal Wounds regardless of how high your casting value was.  Takes the expected damage of Smite from the GK baseline of 0.83, past the standard output of 1.79, and all the way through to 2.92 expected mortal wounds.  Stack this with a Brother-Captain to deliver that at 12", not 6", so you can do it after teleporting in.
*'''Cuirass of Sacrifice:''' Requires the {{W40kKeyword|INFANTRY}} keyword, is not a suit of Terminator Armor like in 7th; 5+ FNP.  Pretty great all around, since the 5+ works to prevent mortal wounds from Perils and Inner Fire.
*'''Fury of Deimos:''' A souped-up storm bolter and replaces one. 30", Rapid Fire 3 S5 AP-1 D1.  Functionally worse than the Primarch's Wrath regular Space Marines get, since it is only D1 and effectively costs 2 points, rather than 0, but still the best weapons relic available to Grey Knights.  You probably shouldn't take it.
**Bolter Discipline does give it SOME new life for a Grand Master parked near some Purgation marines or a Dreadnought, but you're still wasting a slot best served on the Banner or the Cuirass.
*'''Destroyer of Crys'yllix:''' <strike>Souped-up</strike> (Plus 1D is NOT "souped-up") Nemesis Daemon Hammer and replaces one. Sx2 AP-3 D4, still subtracts 1 from hit rolls. Complete waste of a relic slot - GW has clearly established that relics should do more than merely add +1 damage, which has been everywhere else relegated to the "master-crafted" adjective.  Do not take it.
*'''Domina Liber Daemonica:''' All Daemons within a 6" bubble from the character must subtract 1 from their Leadership. What did the hell happen? This thing used to grant additional psychic power.  Still fluffy, but with 6" area of effect, it isn't a game-changer.  The only few relic a Grand Master in a Dreadknight can take, but just like others on this list, it will almost never benefit you enough to make it worth bringing.
*'''Soul Glaive:''' A souped-up Nemesis Halberd and replaces one. Improves the AP by 1, Melee S+1 Ap-3 D3d and rerolls failed hits and wounds.  The re-rolling of wounds is the real kicker, and will actually get the halberd to outperform a set of falchions, but it won't get you up to Teeth of Terra levels, so, once again, just not good enough to justify a relic slot.
*'''Blade of the Forsworn:''' This relic replaces a Nemesis Force Sword only. Melee +1S Ap-3 D3, ignore Invulnerable saves against Daemons. Situationally better than Soul Glaive dependent on your deamon meta or giving a champion a better sword.
*'''Sanctic Shard:''' When a psychic test is taken by the model with this relic you can reroll the result, additional the model with this relic adds +1 to the result of their psychic tests. Virtually an auto-take for your first relic slot.
*'''Augurium Scrolls:''' Any friendly {{W40kKeyword|Grey Knights}} unit within 6" of the model with this relic score an additional hit on an unmodified roll of 6 with all Nemesis weapons. Killer with a unit with Falcons.
*'''Staff of Supremacy:''' This relic replaces a Nemesis Warding staff. When a psychic test is taken for an enemy model within 18" of the model with this relic, the enemy will suffer perils of the warp on a roll of any double.
*'''Artisan Nullifier Matrix:''' Available only for a {{W40kKeyword|Grey Knights Librarian}}. Once per turn when a psychic test is taken by a friendly {{W40kKeyword|Grey Knights}} unit within 6" of the librarian with this relic. You can increase or decrease a dice roll value by 1. (+1 to cast or stops perils.)
*'''Aetheric Conduit:''' Available only for a {{W40kKeyword|Grey Knights Techmarine}}. You can heal 2D3 instead of D3.
