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

===Relics===
*'''Beacon Angelis''': Once per battle, at the end of your movement phase, you can teleport a {{W40kKeyword|Deathwatch Infantry}} or {{W40kKeyword|Biker}} unit from any point on the battlefield or from reserve to within 6" of the bearer and more than 9" from enemy models. 
**With the addition of Litanies of Battle, a Chaplain with an active litany can be beaconed over to our deep strikers.

*'''Tome of Ectoclades''': At the start of each turn, pick a Mission Tactic. Anyone within 6" of the bearer may use that Mission Tactic instead of the one currently affecting the army. <s>Of course, this means a unit needs to have a Mission Tactic to begin with, so vehicles aren't affected</s> ''Your weapons already give you flexibility, now so do your Mission Tactics''.
** Note that in the recent FAQ (v1.4, 29/05/2019), the Tome is capable of giving the Mission Tactic to a {{W40kKeyword|Deathwatch}} unit that does not have the Mission Tactics rule (Either because it is a unit that does not have the rule, or because it is not in a battleforged detachment). Enjoy giving it to your Vehicles! (Page 3, first item)
*'''Banebolts of Eryxia:''' +1 damage to a ranged weapon shooting special ammunition, and each wound roll of 6+ made for any special ammunition causes one extra mortal wound in addition to the normal damage. Cannot be combined with the warlord trait "Castellan of the Black Vault".
**Mighty on Storm Bolters, which can net you up to 8 damage at close range and have more chances to do those MW. And since they happen on a 6'''+''', the Doctrine Stratagems will trigger MW on a 5+. 
**Put on a primaris captain with MC stalker boltrifle and hellfire up, point at a carnifex, and enjoy hitting on a 2 rerolling 1s, wounding on 2+, ap -2, D3 (D4) shots. 
**Master-crafted Bolters and MC Auto-Bolt Rifles will also deal whopping 3 damage a shot (though it's best to point them at the bigger stuff as to not waste damage), which enable Vengeance rounds threaten medium vehicles. That way someone else can use Tempest Shells.
** If the Beta Bolter rules go through, this will be terrifying on a stormbolter terminator captain.
*** They went through. It IS terrifying.
*** Thanks to the FAQ, can't choose Bolter Discipline and Special Ammo at the same time. Not as terrifying, but still a threat.
*'''Dominus Aegis:''' A buffed storm shield. If the bearer does not move, all friendly Deathwatch models within 6" gain a 5+ invulnerable save. ''Good for any of your ranged units, but excellent for Primaris, who fit double the wounds in the same space and have better range (so they need to move less)''.
*'''The Osseus Key:''' Watch Master only. Enemy vehicles get -1 to hit if they are within 9" of him (so, not on deepstriking). Additionally, each time he fights, he can make an additional attack with the Key against a vehicle within 1", and if he hits, he causes d3 mortal wounds. Essentially, a souped up Clavis that doesn't need CP to activate.
*'''Thief of Secrets:''' 2D Power Sword that re-rolls failed to wound rolls against an alien race of your choice (Tau, Tyranids, Orks, Necrons, or Aeldari) picked at the beginning of the game.
