Last Epoch's Portal Charms are a significant quality-of-life feature introduced in Season 2 with the Tombs of the Erased update, designed to streamline dungeon boss farming Last Epoch Gold. These charms allow players to skip the lengthy dungeon floors and teleport directly to the boss fight, saving considerable time and effort when farming specific items or gear.

How Portal Charms Work  
When a Portal Charm is used at a dungeon entrance, it creates a special portal nearby. Instead of entering the dungeon and progressing through multiple floors filled with enemies, players can step through this portal to be instantly transported to the boss room of that dungeon. This bypass eliminates the need to fight through hordes of enemies and traverse the dungeon’s layout, making boss runs much faster and more efficient.

Obtaining Portal Charms  
Portal Charms can be acquired easily by trading with the Black Market Key Trader located in Maj’Elka’s Upper District. Players must exchange three dungeon keys for one Portal Charm. While this exchange might seem costly since it uses up three potential dungeon runs, the time saved by directly accessing the boss fight can outweigh the loss, especially for players focused on farming boss-specific loot or completing builds quickly.

Benefits
1. Time Efficiency: Portal Charms drastically reduce the time spent farming bosses, allowing players to perform more runs in less time.  
2. Simplified Farming: By bypassing dungeon floors, players avoid the randomness and difficulty spikes that can come with modifiers on earlier floors.  
3. Consistent Boss Modifiers: Players still face random floor modifiers applied to the boss fight, maintaining some challenge and variability.

trade-offs 
1. Loss of Floor Loot: Skipping floors means missing out on additional loot, experience, and potential dungeon rewards from clearing full runs.  
2. No Modifier Selection: Players lose the ability to choose or influence floor modifiers that can affect difficulty and rewards.  
3. Key Consumption: Using Portal Charms consumes multiple dungeon keys, which are also needed for regular dungeon runs and respawning at death locations.

Strategic Use  
It is advisable to maintain a stock of dungeon keys to balance between full dungeon clears and boss-only runs with Portal Charms. This flexibility allows players to farm efficiently while still benefiting from the modifiers and loot found in complete dungeon runs Last Epoch Gold for sale.

Summary
Portal Charms have become an essential tool for Last Epoch players aiming to optimize their farming routes and reduce grind time, especially in endgame content where boss drops are critical.
