Editing Warhammer 40,000/9th Edition Tactics/Space Marines (section)

====Psychic Discipline: Geokinesis====

#'''Tectonic Purge – WC6:''' Any enemy units that start their charge within 12″ of the psyker must subtract 2 from the result. 
#*A strong defensive buff, this trait can combine withGrav Pulse strat to make even a Blood Angel unit think twice about charging out of deep strike, or work alone to help keep a unit of Centurions safe. The only major downside is the enemy needing to start within 12″, meaning the Librarian needs to be near the front lines. Combine with Tremor Shells to make charges basically impossible for an enemy unit.
#'''Wrack and Ruin - WC6''': One visible enemy <{{W40Kkeyword|building}} or unit that's wholly in or within a terrain feature> within 18" has to roll 9d6, and for each 5+ (4+ if it's a {{W40Kkeyword|building}}) they suffer a mortal wound.
#*Will outperform Smite, with the caveat that its targeting is heavily restricted.  Deals 2.17 mortals to a non-building, 3.25 to a building.
#*An opponent that knows you have this can simply have one unit member hang out outside the terrain to stop you from casting this - remember, light, heavy, and dense cover are all model-specific rules, not unit-specific.  The only terrain benefit that requires a unit to be entirely within area terrain is Defensible, which allows Infantry, and only Infantry, to choose +1 to melee hit rolls or 5+ if they Overwatch when they're charged, so you generally have to be fighting Infantry and presenting a melee threat for your opponent to bother letting you cast this.
#'''Iron Inferno – WC6:''' Select a point on battlefield within 18″ and visible to psyker. Roll one D6 for each enemy unit within 6″ of that point, deal one mortal wound on a 4+. 
#*This will deal slightly more than a third of a mortal wound, on average, to each target unit, so you need at least 5 units within range to exceed Smite.  Since it's actually no more than 1 wound per target unit, this will generally fuck up enemy character support better than it will a parking lot.
#'''Fortify – WC4:''' Restore D3 lost wounds to one {{W40Kkeyword|Imperial Fists Infantry}} or {{W40Kkeyword|Biker}} model within 12″.  
#*Has a very low WC, making it easy to cast (33/36 means it's slightly ''easier'' than a 3+ attack with full re-rolls), and turning your librarian into an Apothecary with a low chance to fail in exchange for more range.  The healing won't actually stack with an Apothecary's, note.
#'''Aspect of Stone – WC5:''' Add 2 to the psyker’s strength and toughness until your next psychic phase. 
#*Counters the positioning vulnerability in the use of Tectonic Purge, and turns a psyker into something of a melee threat; an assault can only be delayed so much.  Offensively, this is much worse than casting Might of Heroes on yourself from Librarius, while defensively, T4->T6 is -1 to be wounded against Strengths 3,4,6, and 8-11, and -2 to be wounded against S5, which is a reasonable spread.  Won't protect you at all against Poison weapons, of course.  Naturally, if you're bringing this, the Librarian should be carrying a Force Axe, so he can be S8 AP-2 D1d3 - S7 and S9 are both much less useful breakpoints.
#'''Chasm – WC6:''' Select a visible enemy unit that cannot {{W40Kkeyword|Fly}} within 18″ of the psyker. Roll 2D6; if the result is less than the lowest Move characteristic in the unit, it takes one mortal wound; if it’s equal it takes 1d3; if it’s greater then it’s a flat three mortal wounds. 
#*Starts outperforming Smite against M5 or less. Fuck Orks, Space Wolves who brought a Terminator along in their unit, and many severely crippled Vehicles/Monsters.  Against M1/M0 (i.e. a Building) it has the same expected output as Wrack and Ruin against a non-building - otherwise, it does less, while having a less onerous targeting restriction.
#*Another power that can be used to snipe out a character, this power has a 58.33% chance to do a full three mortal wounds against something with the standard six-inch movement (42.13% after accounting for failing the cast), and of course that only increases against slower units – things like Terminators or Death Guard spring to mind.
