Path of Exile 2: All Act 4 side-objectives

Path of Exile 2 extended its campaign to Act 4 in patch 0.3.0, removing Cruel Acts altogether. Thus far, this is the biggest Act if you do all of the side activities across various islands in the peninsula. If you want to speedrun just the main campaign, this can be done in 4 islands.

However, a lot of these optional islands give you permanent buffs, and in general, also provides a very favorable leveling curve. Some of it is just very lukewarm flavor objectives, though. So in this Path of Exile 2 guide, we'll go over all the side-objectives in each Act 4 area, and which ones are the most worth doing.

Path of Exile 2 Act 4 islands order, and all side-content explained

There are a grand total of eight island clusters you can visit in the Act 4 of PoE2 campaign, discounting Kingsmarch (the hub town during this Act). Some of these have roughly level 46-47 monsters, but alll of them will scale all the way up to lvl 50-51 if you're overleveled. Here's the order we recommend:

• Kedge Bay
• Whakapanu Island (main quest)
• Isle of Kins
• Eye of Hinekora
• Ngakanu
• Shrike Island (main quest)
• Abandoned Prison (main quest)
• Arastas (main quest)
• Ngakanu once again (main quest)
• Plunder's Point

Kedge Bay (and Journey's End) objectives

These are honestly not super important (Image via GGG)

• Torn Map Piece (The Kedge Bay): The second Torn Map Piece can be farmed off the remains of a sailor in a small cave with no monsters inside. This area tends to spawn near the northern edge of this map, but the layout may vary. The Torn map pieces are only required if you want to do the Forgotten Bounty optional quest in PoE2.
• Captain Hartlin (Journey's End): Captain Hartlin is an optional boss. Doesn't drop any particularly noteworthy rewards.
• On top of this, Kedge Bay also has the first introduction to the Delirium Endgame mechanic via a sidequest.

Whakapanu Island (and Singing Caverns) objectives

• The Great White One (Whakapanu Island): Is an optional boss.

• Diamora, Song of the Death (Singing Caverns): Important. Story boss, necessary to progress the main quest.

The Blind Beast grants additional Passive points (Image via GGG)

• Beast Pen (Isle of Kins): Skip. This is just a Rare Monster called Mumbok the Enslaved, found by opening one of the beast pens. The other one will have some magic Rhoas.
• The Blind Beast (Isle of Kins): Important. This optional boss drops the Bile-Soaked Tome, which grants +2 Weapon Set Passive points.

Eye of Hinekora (and Halls of the Dead) objectives

The Tattoos provide meaningful buffs (Image via GGG)

• All of the buffs here can be obtained through the optional but important quest, Trial of The Ancestors.
• Navali's Rest (Eye of Hinekora): Talk to navali to receive 5% Increased Maximum Mana.
• Yama the White (Halls of the Dead): Important. Defeating him lets you finish the Trial of the Ancestors, which gives you Hinekora's Tattoo, granting +2 Weapon Set Passive points.

• Tavakai, Tukohama Chieftain (Heart of the Tribe): Final boss of Act 4 in Path of Exile 2.

---

Plunder's Point

This is the spot that the Forgotten Bounty quest (Torn Map pieces) leads to. On the whole, this is just an introductory series of Expedition caches. The more you chain, the better the loot, so it's better to save this one for last if you want to utilize it. After you beat it or die in the process, the League mechanics despawn from this otherwise empty map.
