Harrow PrimePASSIVE Overshield capacity doubled. Start missions at maximum energy.
Condemn
Cast a wave of energy that chains them where they stand. Each enemy held reinforces Harrow's shields.
Penance
Sacrifice Shields to boost Reload Speed, and Fire Rate while converting damage inflicted on enemies into health for Harrow and nearby allies.
Thurible
Channel Harrow's energy into the Thurible to generate a buff. Once finished, kill enemies to bestow nearby allies with bursts of energy. The more energy channeled the greater the reward. Headshots produce extra energy.
Covenant
Protect nearby allies with an energy force that absorbs all damage and converts it to a Critical Chance bonus for all those under the Covenant. Headshots are amplified even further.
CEPHALON FIELD GUIDE
How to play this build.
Tenno. This is the lazy Harrow. Evade keeps you invisible almost forever off a few headshots. Lasting Covenant gives a permanent 200% flat crit chance on headshots. Penance buffs fire rate and reload. You cast almost nothing except the occasional Condemn to line up heads. Get headshots, profit.
How it works
Evade (subsumed over Thurible) gives invisibility that prolongs off headshots, effectively permanent at this Duration off a headshot every ~50s.
Lasting Covenant makes Covenant's crit buff permanent (200% flat on headshots) at the cost of its i-frames.
Penance adds fire rate and reload.
Beyond that you only cast Condemn to lock enemies for easy heads.
Playstyle
1.
Cast Covenant (4) twice for max duration of the crit buff (press 1 for shield, 2 to spend it).
2.
Cast Evade (3) for invisibility.
3.
Get headshots.
4.
Occasional Condemn to lock a group.
Duration, Efficiency, Range, Strength
Very high Duration for Evade and the crit buff.
Efficiency dumped with Primed Flow and Equilibrium.
Range is low (only Condemn uses it).
Strength for Penance and Covenant.
The mods
Blind Rage is the Strength.
Narrow Minded, Primed Continuity are the Duration, Range cost free.
Primed Flow, Equilibrium are the energy base.
Lasting Covenant is the permanent crit buff.
Rolling Guard is status cleanse for the procs that tag you through invisibility.
Stretch is a little Condemn range.
Flexible slots
Archon Stretch over Stretch with an electric companion for passive energy.
Constitution over Archon Stretch if you never use Condemn.
Worthy Comradery aura over Corrosive Projection for +75% headshot crit.
Helminth
Evade over Thurible is the build.
No other subsume is needed.
Arcanes
Arcane Crepuscular for Strength and flat crit damage while invisible, Arcane Precision for pistol damage.
Arcane Pistoleer for a non-Incarnon pistol.
Focus
Any.
Vazarin as a backup for when Evade lapses.
Weapon synergy
Headshot-attractor or headshot-payoff weapons: Scourge, Dual Toxocyst, Knell Prime, Sicarus Prime Incarnon.
Vadarya Prime can self-sustain Evade.
Staying alive
Permanent Evade invisibility plus Rolling Guard for status.
It fails to AoE and environmental procs that ignore stealth, and to a nullifier stripping Evade.
Energy
Primed Flow plus Equilibrium; you barely cast.
Where it struggles
Entirely weapon-carried.
Bosses take the weapon.
It does nothing for the squad (unlike The Red Sermon).
Variants
The The Red Sermon build is the full-kit team-support Harrow.
Strengths and weaknesses
Strong: permanent invisibility, a large permanent crit buff, near-zero casting, very comfortable.
Weak: selfish, weapon-carried, boss-blind.
Who runs this
Players who want the most low-effort possible invisible crit-carry and do not need Harrow's team energy.
