Editing Warhammer 40,000/10th Edition Tactics/Grey Knights (section)

===Characters===

By led unit:
*'''Brotherhood Terminator Squad/Paladin Squad:''' Brother-Captain, Brotherhood Chaplain, Brotherhood Librarian, Grand Master, Kaldor Draigo, Arvann Stern, Aldrik Voldus
*'''Purgation Squad:''' Brotherhood Champion
*'''Purifier Squad:''' Castellan Crowe
*'''Servitors:''' Brotherhood Techmarine
*'''Strike Squad:''' Brotherhood Champion, Brotherhood Techmarine


*'''Brother-Captain:''' A beefed-up Paladin. His led unit gains ''[Sustained Hits 1]'' on their psychic weapons - a rule that has no effect on Psilencers due to the restrictions on stacking bonuses. He also has another buff that lets him re-roll to wound his own gun - Something far more reliable for a buff.
*'''Brotherhood Champion:''' One of only two power-armoured heroes in the chapter and the only one who wants to be in a fight, particularly with enemy characters thanks to using ''[Precison]''. Fortunately, he's made to be that guy by giving everyone including himself ''Fights First'' and re-rolls to hit and wound enemy characters.
*'''Brotherhood Chaplain:''' Gives his unit gains +1 to melee wound rolls like any Chaplain but lacks a Combi-Weapon option...not like it changes much for him. He does however add a 6" bubble that makes enemies take -1  to battle-shock tests. 
*'''Brotherhood Librarian:''' Like the Codex-compliant Terminator Librarian, putting him in a squad gives them a 4+ FNP against psychic weapons. He also gets an old-school psychic power that deals a devastating d6 MWs to himself on a 1, 2d3 MWs to an enemy 18" on a 2+ and 2d6 MWs on a 6. This at least gives him a means to damage anything beyond his squad's power.
*'''Brotherhood Techmarine:''' A purely supportive version of the codex-compliant techie with a built-in Servo-Harness. While he still gets ''Lone Operative'' while being near {{W40kKeyword|Vehicles}}, his ability to fix a vehicle and give them a +1 to hit do not necessarily have to be the same target so you can fix one while buffing another.
*'''Grand Master:''' The closest you get to a Captain. His squad can ignore modifiers to characteristics, tests, and rolls, except for saving throws, and they can be targeted by any strat for 0 CP once per game even if the strat has already been used this turn.
*'''Grand Master in Nemesis Dreadknight:''' While a bit buffed at  T8 Sv2+/4++ W13, it's still not amazing defensively when compared to things like Dreads. Fortunately, the fact that any stratagem used on him will only cost 1 CP regardless of cost means that many defensive tricks will remain affordable.
**His offensive power has Surge of Wrath to give one GMND each turn the ability to re-roll all hits, wounds, and damage rolls against {{W40kKeyword|Vehicles}} and {{W40kKeyword|Monsters}} in melee. This does quite a bit, as both the Nemesis Daemon Greathammer and Nemesis Greatsword have d6s in their damage stats, which can get frustrating since these weapons are made for killing just those sorts of enemies.
**Gun breakdown (now BS 3+, you want the Heavy Incinerator and Heavy Psycannon to go hunting for harder targets):
***Gatling Psilencer: 10 total A*BS*D resolving at 24" S6 AP 0 D1.
***Heavy Incinerator: 7 total A*BS*D resolving at 18" S6 AP-1 D1 with {{W40Kkeyword|ignores cover}} makes this weapon outperform the Psilencer against Sv3+ or better.
***Heavy Psycannon: 12 total A*BS*D resolving at 24" S10 AP-1 D3 makes this weapon outperform both of the others against most targets.  Against W2 it will be 8 A*BS*D and hence outperform the Incinerator against everything while outperforming the Psilencer against Sv4+ or better, while against W1 you need some specific Toughnesses for it to be your best gun.

====Epic Heroes====
*'''[[Aldrik Voldus|Grand Master Voldus]]:''' Led unit has -1 to be hit.
*'''[[Castellan Crowe]]:''' Led unit's Purifying Flames get +1A.
*'''[[Kaldor Draigo]]:''' Led unit has a 4+++ against mortal wounds and 1/battle when charging out of Deep Strike, +3 to the charge roll (meaning you need a 6 to succeed, base odds 72.22%).
*'''[[Arvann Stern|Brother-Captain Stern]]:''' His led unit's critical melee wounds deal +1MW.
