General Sargas Ruk is the final boss of the Saturn system. He can be found on Tethys. He has a possibility of dropping one of the following on death: Ember Helmet, Ember Chassis and Ember Systems blueprints, and the Orokin Cell.
Appearance and abilities
Sargas Ruk resembles a Grineer Heavy Gunner with black and purple armor, using the same weapon and being equipped with a personal shield. However, his shield is much stronger and also recharges almost instantly at a very high rate (approx. 2 seconds, with approx durability of 200). He can create a shockwave by stomping, just like normal Heavy Gunners. In addition, he has access to two extra abilities that he uses often during combat.
Reversal Field: The most annoying skill at his disposal is the Reversal Field. Similar to Mag's Bullet Attractor ability, Sargas Ruk can place a magnetic field around you, shown as a blue whirlwind that encircles the player. It acts as a deflective shield, which reflects your own bullets back at yourself. In other words, if you're using a gun with high damage or high fire rate, you can kill yourself in a matter of seconds. The field disperses after approximately 10 seconds.
Barrier Shield: Sargas Ruk can put up a bullet deflecting shield to provide cover for himself. While it is similar to Volt's Electric Shield ability, it has the additional effect of draining the player's shield in order to set up, instead of consuming energy. However, he tends to move away from this shield, making it much less effective than it otherwise would be. He will only start using this ability when he reaches half health.
Sargas Ruk, like Captain Vor, will always be found on a Grineer Asteroid Base and has the same boss arena. Strangely and somewhat disappointingly, they both share the same animation and pose in the opening cinematic.
Strategy
Once the General is located, take some time to eliminate all other enemies in the room so you can focus on him later. Due to his shield's high recharge speed, a rifle with high fire rate is crucial to sustain damage. In general, you can treat him like any other Heavy Gunner, and stay in mid-range while close to cover. However, it is advised to shoot in short bursts instead of just holding down the fire button, otherwise a sudden Reversal Field can be devastating to yourself. When the Field activates, take this chance to find new cover to adjust to Ruk's current location and reload. Do not use damaging abilities unless his shield is down already, otherwise it may be wasted if his shield regens before you break it, such as if he puts a Reversal Field on you.
It goes without saying that having teammates will assist greatly in taking down his shields. If you are in a group instead of soloing, position your group in different directions around him instead of clustering together. This can allow you or your team to flank Sargas Ruk when he puts up a Barrier Shield against one of you and sustain damage to prevent his shield from recharging. A high difficulty group tactic would be to shoot in turns instead of in unison. This way one can shoot while the other reloads, decreasing the number of opportunities for the General to recharge his shield.
It appears that bolts such as those fired by the Boltor and the Bolto are unaffected by the General's Reversal Field, allowing a user of such weapons to completely ignore this ability. The bolts are stopped by the Barrier Shield just like bullets though.
Trivia
- Sargas Ruk is generally the second Grineer boss that players will encounter, after Captain Vor.
- According to the mission briefing, Sargas Ruk had been raiding and annexing Tenno-controlled dig sites in the region, which is the main reason that led to him being targeted for assassination. He is also the main Artifact Hunter of the Grineer faction.
- It is said that Ruk has a deep hatred for any non-Grineer. He also considers flesh as a flaw, and implanted many body modifications into himself as a result of his pursuit for "Grineer perfection".
