Strategic Engineering
Those engineers who choose the Strategic Engineering discipline combine their technological expertise with their ability to coordinate and command others into effective battle squads.
Bonus Proficiencies
Strategic Engineering: 3rd Level
You gain proficiency in one skill or weapon and one specialist's kit of your choice. Additionally, when you engage in crafting with your chosen specialist’s kit, the rate at which you craft doubles.
Aura of Command
Strategic Engineering: 3rd, 5th, 11th, and 17th Level
You emanate an Aura of Command that bolsters the cooperative capacity of you and your allies.
Your aura has a radius of 5 feet and increases by 5 feet you reach 5th level (10 feet), 11th level (15 feet), and 17th level (20 feet). Additionally, you can only use the features of your Aura of Command while there is at least one allied creature, that isn’t incapacitated, within its range.
Once per round, you can use your reaction to add your Intelligence modifier to one attack roll, ability check, or saving throw made by an allied creature who is not incapacitated within your aura. Alternatively, once per round, when an ally within your command aura attacks a creature that you can see, you can expend a superiority die and enhance that ally’s attack (no action required), using one of the maneuvers that you know.
You can use this feature four times, and you gain more uses at higher levels, as shown in the Modification Slots column of the engineer table. Each time you use this feature in excess of your proficiency bonus, your tech point maximum is reduced by 1 until you complete a long rest. You regain all expended uses when you complete a long rest.
Tactical Superiority
Strategic Engineering: 3rd, 5th, 9th, 13th, and 17th Level
You learn maneuvers that are fueled by special dice called superiority dice. See chapter 13 for the maneuvers list.
Maneuvers Known
You learn four maneuvers of your choice, and you learn an additional maneuver at levels 5, 9, 13, and 17. Many maneuvers enhance an attack in some way. You can use only one maneuver per attack, and you may only use each maneuver once per turn.
Each time you learn new maneuvers, you can also replace one maneuver you know with a different one.
Superiority Dice
You have two superiority dice, which is a d4, and you gain more at levels 5 (3), 9 (4), 13 (5), and 17 (6). A superiority die is expended when used. This die changes as you gain levels: to d6 at 5th level, to d8 at 9th level, to d10 at 13th level, and to d12 at 17th level.
You regain all of your expended superiority dice when you finish a short or long rest.
Maneuver Ability
Your maneuver ability varies based on the type of the maneuver you use. You use Strength, Dexterity, or Constitution for physical maneuvers (your choice), Intelligence, Wisdom, or Charisma for mental maneuvers (your choice), and an ability of your choice for general maneuvers. You use this ability whenever a maneuver refers to your maneuver ability. Additionally, you use this ability modifier when setting the saving throw DC for a maneuver you use.
Maneuver save DC = 8 + your proficiency bonus + your maneuver ability modifier
Tactical Confluence
Strategic Engineering: 3rd Level
While your Command Aura is active, when you use a maneuver and expend a superiority die on your turn, you can use a bonus action or reaction and expend one use of your Potent Aptitude to add your Potent Aptitude die to the DC of any imposed saving throw of the maneuver.
Staged Ordinance
Strategic Engineering: 6th Level
You can use maneuvers that require a weapon attack when you or an ally in your command aura casts a power that requires a force or tech attack and you can use maneuvers that require a hit with a weapon attack when a creature fails a saving throw against an explosive or power controlled by you or an ally in your command aura. If multiple creatures failed the saving throw, you choose which one to impose this maneuver upon.
Calculated Gambit
Strategic Engineering: 14th Level
When you make an attack roll or impose a saving throw with an explosive, power, or weapon you control, you can reduce your attack bonus or the save DC by an amount equal to your proficiency bonus. If the attack roll hits, or the creature fails the saving throw, you can impose a maneuver you know without expending a superiority die, rolling a d4 in its place. If multiple creatures failed the saving throw, you choose which one to impose this maneuver upon.
High Command
Strategic Engineering: 18th Level
Any battle is yours to control.
When you roll a critical hit with an attack, you can expend a superiority die to immediately take an additional turn. Once you use this ability you cannot use it again until you finish a long rest.
In addition, you can expend four tech points to regain an expended superiority die, or expend a superiority die to regain four expended tech points, both up to their maximums.
