Path of Exile was released in 2013, more then a decade ago. One of the most mesmerizing things about this Game are the ever alternating Seasonal Leagues, introducing a new main mechanic into the game. As soon as a Season gets replaced by a new one, certain aspects of the previous one will be implemented as a core feature of Path of Exile.
Over those 10 years, there have been many league mechanics stacked up, which most of them still have some impact into current gameplay.
The first League Mechanic introduced in 2013 are Rogue Exiles. These enemies are randomly spawned in Maps and resemble a player character by using abilities and classes usable by players. These Rogue Exiles are strong rare enemies with some of them requiring a specific player level to be able to appear. Their skills also often showcase skins for abilities purchasable as a microtransaction.
Rogue Exiles yield a large amount of items, including one for each inventory slot.
The second League Mechanic introduces was Nemesis. Nothing out of the Nemesis League remained in the game (besides the Items introduced during that time like Headhunter and Two-Stone Ring). Only new mechanic added to the game were Shrines. These Shrines can be clicked by a player which grant a temporary buff to them. Shrines are guarded by many enemies.
Shrines do not offer any additional loot themself.
Every map has a chance to contain a Vaal Side Area. Those are small maps located inside your current map, containing corrupted enemies. A Vaal Side Area can have different modifiers, similiar to a regular map. A Vaal Side Area cannot contain any other league mechanic or Trial of Ascendancy.
At the end of the Vaal Side Area, you will find a Vaal Vessel which contains Vaal Skill Gems, Vaal Fragments and corrupted equipment
Strongboxes can be found everywhere in a map, containing specific loot depending on the kind of strongbox it is. Whenever clicking on a Strongbox, groups of enemies will start spawning. As soon you defeated those guards, the Strongbox will throw its loot on the ground.
Strongboxes can be upgraded like items, with their quality increasing and rarity – allowing higher loot quantity and rarity. Strongboxes also contain specific modifiers like maps which can easily lead to a player’s death due to deadly effects occuring whenever activating the Strongbox.
Strongboxes contain various amount of items depending on it’s type:

Slaying a Beyond demon has a chance to reward Tainted Currency, which can be used to modify corrupted items.
Tormented Spirits are enemies that can be randomly encountered in your maps. They try to flee, empowering other enemies whenever coming into contact with them. These modifiers are shown in green on the Tormented Spirits. Whenever they possess other enemies, they improve their item drops.

The Talisman League was introduced in 2015. It was the first League which had no additional League Mechanic for Hardcore in comparison to Softcore.
Today, Talismans do not have any impact in the game, but can rarely dropped or obtained by league mechanics.

Every Essence monster will drop the listed Essences above its head.
Essences are an important crafting currency which allow players to target a specific stat whenever reforging an item.
Introduced with the Breach League in 2016, players can encounter Breaches randomly in every map. Clicking on them will temporarily open a growing circle which spawns enemies consistently. After a specific time, the circle of the Breach shrinks rapidly and vanishes.
Players can collect Breach Splinters on each Breach they encounter, which are related to one of the Breach Lords: Xoph, Tul, Esh, Uul-Netol and Chayula. The Splinters are rewarded by either killing enemies, or opening Clasping Hands, a kind of Chest during a Breach.
Combining 100 of these Splinters creates a Breachstone, allowing players to travel to the Breach Lord and defeat them.
Defeating enemies in a Breach rewards Splinters related to their Breach Lord.

Harbingers drop Currency Shards when defeated. While most of the Currency Shards have low value, they can also reward high valuable Shards like Mirror Shards or Fracturing Shards.
Players can encounter Abysses in every map they enter. They are indicated on the minimap by a green dot. Steppin on it makes the Abyss travel through the map until it stops, and cause waves of monsters to spawn.

Heist is a new individual mechanic that players have to engage only if they want to. During maps, players will sometimes encounter a Smuggler’s Cache, containing Blueprints and Rogue’s Marker. The Rogue’s Marker can be used in a Town or Hideout to open a portal to the Rogue’s Harbor.
In the Rogue’s Harbor, players can complete Heists in different locations by using the Blueprints obtained in maps. The goal is to obtain as much loot as possible before Guards are alerted. A bar fills everytime chests are opened in a Heist. When the bar reaches full, players have a short grace period before all doors become closed and guards are alerted. If a player dies while the guards are alerted, all loot obtained in a Heist is lost.
Players can be accompanied by other rogues, which can be leveled and even equipped. A Heist will require different skills by the NPC’s accompanied (Lockpicking, Brute Force, Demolition and more). Each NPC can fulfill one of these roles, which have to be level up to complete more difficult Heists.

After completing a Ritual, players can click the Altar to redeem rewards in exchange of their Tribute. The loot table can be rerolled for some of the available Tribute, and items can be deferred. Deferring items cost a little amount of Tribute, and cause the item to appear again in the loot table of a future Ritual.
Players can obtain Ritual Fragments which create a Ritual Vessel whenever combining 100 of these fragments. This Ritual Vessel can be used on a Ritual Altar in a map to store the defeated monsters in the Vessel. This will create a Blood-filled Vessel which then can be used in a map device to empower the Rituals in the new map.
As many other League Mechanics, the loot offered in Rituals ranges from the regular loot pool. (Currency, Armor, Divination Cards,…)
An Expedition can be encountered during a map, containing one of four specific NPCs leading the Expedition.

Enemies will only gain the modifiers of previous crates, becoming more difficult the later they have been excavated.
Players receive various smaller currencies, multiple ones for each NPC. Additionally, certain items used for resetting the Loottable of the NPCs and Logbooks can be found.
Logbooks are maps that lead to a giantic Expedition with dozens of explosives to use, granting a lot of rewards.
Every NPC offers a unique way to obtain items:
Archnemesis has replaced all previously existing modifiers to enemies in your maps. This League mechanic will have forcefull impact for all players in Path of Exile. Magic and Rare enemies found throughout your map will have additional modifiers, increasing and randomizing their difficulty and rewards.
The loot acquired from Magical and Rare enemies are random, but are increased due to specific Archnemesis modifiers on them. This can cause enemies to reward multiple items with sockets, drop dozens of currency items and more.

Players can apply the influence of one of these bosses on their map device. After completing 28 maps with a certain influence, players are rewarded with a map leading up to these bosses. Due to Atlas Talents, these bosses can also become the Uber-version of themself, granting additional loot. These Uber-bosses are considered the hardest ones in the game.
Whenever completing maps with the influence of either Searing Exarch or Eater of Worlds, players can obtain Eldritch Ichor and Eldritch Ember. These items are used to add a specific Implicit on your equipment if they are not already influenced by anything else or corrupted. The influence of one of those bosses will cause certain Eldritch Altars to spawn in maps, allowing players to choose to earn additional reward in exchange of increasing the difficulty of the map.
Eldritch Ichors and Eldricht Embers are rewarded by killing Eldritch enemies in maps, or by defeating the Bosses

This will cause the NPC to offer players a specific row of maps to complete, which can also be modified by currencies, fossils, Delirium orbs and become corrupted.
Atlas Memories will feature a specific League Mechanic from all available ones.
The Forbidden Sanctum is a rogue-like Tower that has to be climbed by players. The further they progress into the Sanctum, the more difficult it becomes.
Each Room can yield various enemies and rewards Currency at the end of each room. Players can be granted Boons which empower them, but also Afflictions which will grant them a debuff which makes their run more difficult.
Players can use Relics to grant themself additional bonus before each run.
A Sanctum is divided into 4 different Floors with 12 Rooms each.
