Info

• Protea flourishes with a graceful leap, expending 25 Energy to jump up 1 meter then scattering 3 grenades along the 45, 90, and 135 degree angles, thrown in an arcing trajectory toward the aiming reticle. Tapping or holding down the ability key (default 1 ) causes Protea to throw one of her two grenade types: the Shrapnel Vortex or Shield Satellite.
  • Energy cost is affected by Ability Efficiency.
  • Throwing animation speed is affected by casting speed, from mods such as  Natural Talent and  Speed Drift.
  • Initial jump height, grenades per throw, grenade spread angles are not affected by mods.
  • Tap/Hold cast can be inverted in the Options menu.
• Protea reconfigures her two grenade types depending on the casting method:

• Shrapnel Vortex
• Shield Satellite

• Tapping the ability key scatters Shrapnel Vortexes. On impact with a surface or object, shrapnel grenades bounce away and fall to the ground; landing on a horizontal surface triggers the grenade to release a vortex of flying shrapnel, lasting for 10 seconds. Each shrapnel vortex spans a 2 / 3 / 4 / 4 meter radius, inflicts 100 / 150 / 200 / 250 damage per second with a 33% status chance and a 100% chance to stagger enemies slightly or strongly on each hit.
  • Grenade duration is affected by Ability Duration.
  • Vortex radius is affected by Ability Range.
  • Damage per second is affected by Ability Strength.
  • Status chances are not affected by mods.
  • Shrapnel Vortexes do not require line of sight to damage and stun enemies within range.
• Shrapnel grenade uses a custom model that resembles the shape and pattern of a baseball. When deployed, the grenade spins rapidly in place while emitting a glow of energy particles.
• Shrapnel Vortex visually creates a sphere consisting of multiple trails of energy particles that encircle the grenade at high speed.

Holding down the ability key instead scatters Shield Satellites. On impact with a surface or object, shield satellites bounce away and fall to the ground; landing on a horizontal surface anchors the satellites in flight to seek out allies within 2 / 3 / 4 / 4 meters. When Protea or her allies move in range of a satellite, it will attach to the nearest target and orbit around 1 ally, instantly restoring 200 / 300 / 400 / 500 Shield points then constantly recharges 25 / 30 / 40 / 50 shield points per second until it reaches the Overshields limit. Each shield satellite lasts for 10 seconds once deployed, or until its target's shield gate is triggered; upon shield gate trigger, the satellite is destroyed and provides 2 extra seconds of invulnerability to its target.

• Pickup radius is affected by Ability Range.
• Shield restore on attach and shield points per second are affected by Ability Strength.
• Satellite duration is affected by Ability Duration.
• Limit of allies per satellite, and shield gate extension are not affected by mods.
• Satellites do not require line of sight to be picked up by allies in range.
• Each satellite's pickup radius will briefly appear when first deployed.
• Shield points per second is constant throughout a satellite's lifetime, allowing shields and overshields to replenish upon taking damage.
• Eligible allies for satellite attachment include: Protea, other Warframes, Companions, Eidolon Lures, summoned allied units such as Specters, allied Invasion units, Hostages, Kavor Defectors, Sortie and Arbitrations Defense Operatives, and Defense Objects coming into the satellite's range.

Shield satellite uses a custom model that resembles a spherical device with visible mechanical parts. When deployed on the ground, the satellite floats and weaves around the air several meters above while an energy stream anchors it to the surface.

Shield satellites visually orbit their target in a steady clockwise motion, directly facing it while funneling an energy stream to reinforce shields, represented by a translucent cluster of connected hexagons.

• Ability Synergy:
  • Shrapnel vortexes contribute damage to  Temporal Anchor's recorded damage pool for the implosion on rewind.
• Can be recast while active to deploy multiple instances of shrapnel vortexes and shield satellites.
• Casting Grenade Fan is a full-body animation that allows movement with enforced height displacement.

Tips & Tricks

• Grenades travel along separate angles and in an arc. Aim at the ground to quickly deploy them in close proximity, or aim high to throw and scatter them over a long range, far apart from each other.
• Protea will always jump before throwing her grenades, even while she is airborne. Take into account the height difference when casting to land your grenades where you intend.
• Jump into the air and use Aim Glide while casting Grenade Fan repeatedly. This allows Protea to reorient herself by moving the reticle between throws to create lines of Shrapnel Vortexes facing different directions.
• Shrapnel Vortexes stun and push enemies away by staggering them on hit. Throw close together to quickly stack damage, procs, and stuns.
• Shield Satellites persist on allies even after Overshield cap is reached. Throw multiple times to provide autonomous cover for your team, that replaces destroyed satellites to protect allies as their shield gates are triggered by enemy damage.
• Activate  Temporal Anchor and throw multiple Shrapnel Vortexes at groups of enemies. Direct damage from the vortexes, including damage over time from the status effects, are all recorded to fuel the temporal implosion.
  • Energy points spent on casting Grenade Fan will be restored by Temporal Anchor's rewind.
• Grenade Fan is the least expensive ability in Protea's kit, making it ideal to power up her passive Ability Strength bonus on every fourth cast.
