After the death of the king, Noctis and the rest of the team know, that the only viable course of action is to continue their journey. The first step is reaching a man named Cor, who decided he wants to aid them. To fight with the Empire, the prince will have to acquire the relics of the ancestors.
Recommended level: 5
After reaching the workshop, head to the garage, in order to talk to Cid. Afterwards, enter the Regalia and head over to the next location on the map. There, you will meet Monica, who will tell you a bit about the situation in the occupied city. You can also equip your heroes with better weapons and accessories at the merchant. These will really come in handy, as there are a lot of fights ahead of you.
After preparations, run in the direction of the tomb marked on your map. On your way you will encounter flying creatures - you can defeat them easily using teleportation and Prompto's special ability. When you reach the tomb, enter it. Noctis will acquire a mighty weapon - the Sword of the Wise, which is absolutely worth equipping (it steals health points when damaging enemies, so it is worth using it in key moments and consuming potions to further enhance the effect).
The Power of Kings
Recommended level: 6
Cor has told you about thirteen powerful relics, which all rest in different tombs. One of them is located nearby - run in the direction of the marker. On your way you will encounter a very powerful enemy (level 30+!), together with some weaker characters. Using the fact that Cod is currently accompanying you, you can try fighting this foe, however, you should be extremely careful, as even a single blow can rid you of all of your health points. If you prevail, you will gain a lot of experience points. The case is very similar with the two robots located nearby.
After the fights, venture into the tunnel - Cor will leave the team, after giving you the key. Keep running forwards, and when you reach the wires on the ground, follow them. Turn on the generator, which will light up the entire cave. Keep going further, on your way you will find many off-shoots, where there are additional items for you to collect, another generator, and new types of enemies - goblins and tarantulas. Therefore, it is worth exploring these side-tunnels.
At the end you will run into a single Arachne (level 13), who is a much more challenging enemy. Afterwards, you will finally reach the royal tomb's entrance, where you will acquire another kingly weapon - the Axe of the Conqueror. It is a very powerful axe, perfect for large and slow targets. Leave the room and head to the surface.
Declaration of War
Recommended level: 8
After a phone call with Cor, it will be time to go on the offensive. Head to a meeting with Monica and then travel to the recess in the gorge, which marked on your map. The team will split up - follow Cor, who will be your companion during this mission. Keep heading forwards and fighting consecutive squads of imperial soldiers. On the area of the complex you will also find several useful items. After a few skirmishes, you will jump down to a road, in order to join the rest of the team. After a few moments the first serious enemy in the game will appear..
Boss fight - Logi in his MA-X Cuirass
You must begin by wiping out all of the weaker foes from the battlefield. Use warping, in order to get to the snipers and eliminate them quickly. Do the same with the melee oriented enemies. The boss's most powerful weapon are his rockets, which can damage you greatly and finish you off in one strike. This is why you should avoid standing in one place and also stay clear of the blast zones at all cost. The boss is much less effective in melee combat - his stomp, and other attacks, are easily dodged. Use the techniques of your companions + support your efforts with magic. Every once in a while, Logi can be stunned, and he will be lying defenceless on the ground for a short period of time. After the fight, you will gain a lot of experience points, and the chapter will come to an end.
