Ascension is a unique game mode unlocked during the Jade Shadows quest. It entails the Tenno defending a Mote Collector, then transporting a capsule up a long elevator and to extraction, defending against the Corpus all the while.
Mission start
"Operator! When Jade— left us— this area was infused with the light of her motes. A power the Corpus want to take for themselves. Not today! Ordis has gained control of the mote collectors. They work for the Operator now. Protect them."
"This cavern is infused with Jade's Motes. The Corpus have set up mote collectors to extract Jade's energy from the air. Due to— BRAINDEAD— basic security protocols, the collectors are under our control. Operator, defend the first one."
"The walls of this cave are saturated with Jade's final energy, her Motes. The Corpus have no shame, and they aim to harvest her motes for their own twisted purposes. But not if we get to them first. Defend the filtration system."
Activating mote collector
"Bringing the mote collector online. Defend it!"
"Protect the collector while it draws motes from the air. Ordis would hate for more of Jade to be turned into TERRIBLE WEAPONS."
"First things first: defend the marked collector while it siphons motes from the cave."
If the collector dies
"Ordis is getting an 'error 826570' from the collector… whatever that means, it cannot be good. Its internal timer has reset – you must not let it take damage!"
"Any critical failure of the collector will require that it reboots and begins again. Please keep the equipment safe, Operator!"
"Operator! The collector's systems suffered a critical failure and are now rebooting from the beginning. You must defend it
"Ah-yes! In the manual for this thing, it says 'Excessive Concussive Force to the Collector is Not Recommended For Optimal Use.' Well, perhaps if that stopped happening…."
"While Ordis would never tire of— STANDING AROUND— cheering you on, if you do not protect the collector, we will never progress."
"Ordis must admit that he is very impressed with how durable this collector is! Even if the Operator has let it suffer so much damage that it is resetting…."
"Uh oh… it seems that the collector has taken serious damage. It's going to have to start the process over again. Keep defending it!"
"The process is starting over again. [sigh] And we were so close…."
Defence complete
"Fantastic! The Capsule is full of motes. Now, we can escort it up the elevator!"
"The Capsule is ready for transport to the surface."
"The Capsule is ready. Onward and then upward!"
Approaching elevator
"Ordis has unilaterally enabled air support that will boost the height of your gallant leaps, enjoy!"
"Sending air support to help you jump higher."
"Ordis has preemptively supplied you with unique air support. You will be able to jump higher! Have FUN!"
Boarding elevator
"What??? The elevator's power lines have been severed? You will have to supply power manually. Find ionic charges scattered about. You do not want to take the stairs."
"Starting elevator ascension and… ugh, they have cut the power. Ordis is afraid you will have to power it manually. Look for ionic charges."
"Ordis fears they have cut power to the elevator. Find ionic charges nearby, or else we will be going nowhere."
Collecting a Sister beacon
Ordis: [gasp] "A Sister Beacon? Trigger too many of those and you will have to fight a Sister of Parvos. SO TRIGGER THEM."
"Operator! What have you done? That was a Sister Beacon! Do that again and one will join the fight."
"Those Sister Beacons are meant for the Corpus Troops to call in backup! PICK A FIGHT."
"Willfully triggering those Sister Beacons? Ordis— HOPES— fears his Operator is looking for trouble!"
"Operator, those Sister Beacons are for the Corpus to use in emergencies! [gasp] Are you issuing a challenge?"
"Operator! Those beacons are set up to summon a Sister of Parvos! If we meddle with them, she is certain to arrive!"
"Triggering one Sister Beacon may be overlooked, but tripping all three of them will undoubtedly be seen as provocation— DO IT."
"Keep triggering those Beacons and the Sisterhood will attempt to eliminate you. Ordis would like to see them try!"
"If you insist on triggering those Sister Beacons, Ordis suggests you prepare for an extremely hostile response. SWEET."
New elevator
"Auxiliary elevator inbound. Full of— CORPSES— Corpus."
"Corpus reinforcements! Inbound to your position."
"Reinforcements arriving via the auxiliary elevator bay. Should Ordis tell them they are— GOING DOWN?"
If the elevator is out of power
"The elevator is out of power! Find more charges, or it is stuck here!"
"Operator, the elevator has stopped! Find more ionic charges!"
"The elevator's power is depleted. Operator! Without more ionic charges, it goes not an inch farther."
"Time to recharge the elevator!"
When the elevator has completed ascent; Sister of Parvos defeated
"We have reached the top! But now we must escort the capsule to extraction. Be careful not to slip; it is a loooooooong way down."
"Now that we've reached the top, they will stop at nothing! Protect the capsule!"
"We're almost done – one final stretch. We have to get the capsule to extraction."
If the Capsule has low health
"Hurry! The enemy is close to destroying the capsule!"
"Protect the capsule – it is suffering grievous damage!"
"The capsule is taking critical damage, Operator!"
"The Corpus are dealing serious damage to the capsule!"
If the Capsule’s shields are depleted
"Stars! The capsule's shields have failed. It will stop moving until it rebuilds them."
"Operator! The capsule is rebuilding its shields and will not move until it is done."
"The capsule has to rebuild its shields, and is diverting all propulsion to that."
"Until the capsule's shields are back up, Ordis is afraid it will not budge."
Mission success
"You have extracted the capsule. Mission complete!"
"The capsule is secure and the enemy have been denied more Jade Motes. Ordis could not be more delighted with the Operator…."
"Ordis is just so thrilled that the Operator has succeeded. Well done!"
