The Witch's Ardent Research Mission Guide

In Memortis Shore Ruins of Time, you'll be tasked to gather the remaining Titans and face Irontomb. Move forward and follow the path until you see Mydei.

Talk to Mydei, and once you finish the dialogue, a battle will occur. Finish the battle and the dialogue right after, then continue down the path until you see Cipher.
You'll also get the Imperial Ring of Strife Mission Item after the conversation with Mydei.

Talk to Cipher and finish the dialogue. Once you finish the dialogue, continue moving forward and use the Janus Passage to get to the other side. Keep moving until you see Castorice near a statue.
You'll also get the Trickery Coin Mission Item after your conversation with Cipher.

Talk to Castorice and finish the dialogue. The statue will disappear and you will obtain the Winter Blossom of Death Mission Item after talking with Castorice. Move forward right after and you'll notice a giant ball blocking your way.
Approach it and use the power of time to remove it. March 7th will help you remove the ball, and then you can proceed.

Ride the elevator down, and a short dialogue will commence. Finish the dialogue and follow the golden blood, which will lead you to Hyacine. Talk to Hyacine and interact with the golden harp.
After your conversation with Hyacine, you'll get the Skybound Spirit Kist Mission Item. Continue following the golden blood and it'll lead you to Anaxa.

Talk to Anaxa and you'll be tasked to complete the Worldbearing Ceremony, which is a short puzzle. Approach the crystal and interact with it to start the puzzle.
For the first wish, follow the marker and pass through the wall of light. You'll be teleported next to a Prophecy Tablet. Solve the tablet, and the wooden boxes will disappear, allowing you to approach the crystal and get the first wish.
After the dialogue, follow the marker and go up the ramp. Pass through the next wall of light and you'll be teleported next to the second crystal. Approach it and get the second wish.
For the third crystal, take the left path and ride the elevator down. Follow the marker and go up the stairs to get to the last crystal. Approach it and get the third wish.
Go back to the crystal in the middle and interact with it. Finish the dialogue and you'll get the Jade of Reason and Wish of Worldbearing Mission Items.

Go down the elevator from earlier and follow the marker. It will lead you to Cerydra and Hysilens. Talk to them and finish the dialogue, then climb the branch again to see the golden blood.

Follow the golden blood and ride the flower up. Climb up the stairs to the right and it'll lead you to Trianne and Trinnon. Talk to them and they'll ask you to interact with the scrolls in the room.
Just follow the marker and interact with the two scrolls nearby. Talk to Trianne and Trinnon again, then head outside and follow the golden blood.

Ride the platform to the other side. Go through the door and ride the elevator down. This will take you to another short puzzle like earlier.
Interact with the crystal to start the puzzle. For the first part of despair, pass through the wall of light in front of you to get teleported to another area. Next, walk to the wall of light on the right and pass through it.
This will take you to the first crystal. Interact with it and shatter the first part of despair.
From the first crystal, pass through the wall of light in front of you to get teleported to another area. From there, go to the right and pass the wall of light. This will take you to the second crystal. Interact with it and shatter the second part of despair.
From the second crystal, follow the path to the right and it'll lead you to a Prophecy Tablet. Solve the tablet to remove the wooden boxes blocking the way. Go down the ramp and interact with the third crystal to shatter the third part of despair.
Interact with the crystal that has the Worldbearing Mark to finish the puzzle. Proceed with the dialogue and you'll receive the Despair of Worldbearing Mission Item.

Ride the elevator down and follow the kid that appeared. Go through the Janus Passage to get to the other side. Go up the stairs and interact with the spirit basin.

Finish the dialogue and go up the stairs to see Aglaea and Tribbie. Talk to them and finish the dialogue. Talk to Cyrene to get to the next area and start the Final Flame-Chase Journey.

Set your team and set out on the Final Flame-Chase Journey. You'll be transported to where Irontomb will be born. Finish the opening dialogue and follow the marker. Use the Janus Passage to get to the other side.
Follow the marker and it'll lead you to Phainon. Proceed with the dialogue, and a battle will commence.

You'll be fighting against The Vessel of Destruction, Khaslana. In this battle, Khaslana will only summon some clones of the Flame Reaver and he doesn't really do anything special. Keep attacking Khaslana until his HP is depleted.
Right after the fight with Khaslana, you'll face Irontomb.

After the dialogue and cutscene, a battle against Irontomb will commence. Fight against Irontomb and use Heroes, Ever Ablaze to reduce its Amphorean Hatred. It will also heavily damage Irontomb.
If the Amphorean Hatred gets to 100%, you'll automatically lose the fight, so keep an eye on it! When it reaches 1% HP on the second phase, some dialogue happens and a cutscene will happen shortly after. Proceed with the dialogue, and the mission ends.

Here are some recommended teams that will make the battle against Irontomb easier. Characters with AoE attacks have a much easier team dealing with Irontomb because the damage its summons take is shared with it.
If the battle proves to be too difficult, you can change to Casual Mode when you get defeated to make it easier.
