In Path of Exile, the quest “The Ruler of Highgate� serves as a significant milestone in Act 4, helping to expand the game's complex narrative while providing players with the opportunity to face off against some of the game's most formidable enemies. This quest involves investigating the mysterious happenings in Highgate, and it will eventually lead you into an encounter with one of the key figures of Act 4, Kaom’s Herald. To successfully complete the quest, you’ll need to engage in exploration, boss battles, and a series of decisions that will shape your journey through Wraeclast. Below is a detailed walkthrough to help you navigate The Ruler of Highgate and succeed in completing Path of exile currency.

Starting the Quest
Before you embark on The Ruler of Highgate, you must have completed the quest Kaom’s Dream, which concludes the previous portion of Act 4. After defeating Kaom, you’ll return to Highgate, where Dialla, an important quest NPC, will give you crucial information regarding the quest.

Upon returning to Highgate, you’ll speak with Dialla, who tells you that the Emperor's Herald, one of Kaom's emissaries, has been causing havoc in the area. Dialla believes the Emperor’s Herald is hiding in the Dried Lake area, and you are tasked with investigating the region to uncover more about what’s happening.

Key Objectives of the Quest
1. Speak to Dialla in Highgate
After completing Kaom's Dream, head to Highgate and meet Dialla. She will tell you that the Emperor's Herald is responsible for much of the current chaos in the area. She asks you to head to The Dried Lake, where the Herald is said to be hiding.

At this stage, the quest The Ruler of Highgate will officially begin, and you’ll gain access to The Dried Lake area.

2. Travel to The Dried Lake
The next task in the quest is to head into The Dried Lake, a large, dangerous area located in Act 4. The Dried Lake is filled with powerful enemies and remnants of Kaom’s forces, which are primarily composed of undead soldiers and various creatures loyal to Kaom.

While traversing the Dried Lake, be prepared for intense combat. The area can be overwhelming, so be sure to have your flasks and health regeneration prepared for the battles ahead. The Dried Lake is also a great area to farm loot and experience, so take your time to clear the area thoroughly, as there are many hidden treasures and opportunities for improvement.

3. Defeat the Emperor’s Herald
Phase 1: The battle begins with the Herald summoning minions to fight alongside him. These minions can be difficult to manage, so it’s crucial to keep your focus on clearing them out while avoiding the Herald’s more powerful attacks.

Phase 2: Once the Herald’s minions have been dispatched, he will shift his focus to using more powerful abilities that target you directly. Keep an eye on his area-of-effect skills, which can deal devastating damage if not dodged properly.

Phase 3: At low health, the Herald becomes more aggressive and may use damage-over-time effects, adding another layer of difficulty to the encounter. Be sure to keep a close watch on your health and flasks.

4. Return to Dialla in Highgate
Once you’ve defeated Kaom’s Herald, return to Highgate and speak to Dialla to complete the quest. She will congratulate you on your success and reward you with experience, currency, and possibly new item rewards to improve your character. This marks the end of The Ruler of Highgate quest.

Conclusion
The Ruler of Highgate quest is a critical part of Act 4 in Path of Exile that pushes the narrative forward and presents players with a thrilling challenge. By defeating the Emperor’s Herald, you not only advance in the story but also gain valuable loot and experience to aid in your journey through Wraeclast. Be sure to prepare carefully for the tough battles ahead, and enjoy exploring the rich lore of Kaom’s forces as you uncover more about the game’s epic world. With this guide, you'll be well-equipped to buy Path of exile currency in The Ruler of Highgate and continue your path toward victory.
