In Path of Exile 2, Catalysts are unique items that play a crucial role in item crafting, specifically by adding quality to rings and amulets that increases certain modifiers. Here are the detailed mechanics surrounding catalyst trading:

What are catalysts?

Function: Catalysts are used to increase the quality of jewellery, with each type increasing a specific set of modifiers. For example, a Physical Catalyst increases physical stats, while a Lightning Catalyst increases lightning damage or resistance.Quality cap: All catalysts increase quality by a maximum of 20%, which can significantly boost the item's modifiers.

Acquiring Catalysts

Drops: Catalysts drop from various sources in the game, most notably from Breaches and other end-game content such as Delirium or Legion encounters.Crafting: Some Catalysts can be crafted or obtained through the reforging process at the Reforging Bench, where three of the same Catalyst can be reforged into a random Catalyst of the same level.

Trading Catalysts

Currency exchange: Catalysts are traded through the in-game currency exchange system, where players can list, buy, or sell Catalysts at rates relative to other currencies such as Exalted Orbs or Chaos Orbs.Market DynamicsPrice Fluctuations: The price of Catalysts can fluctuate based on the demand for certain builds or crafting strategies. Some catalysts may be more valuable due to their usefulness in popular builds or their scarcity.Spread Trading: Players can buy and sell Catalysts at different prices to take advantage of the spread between the buy and sell prices. For example, if you can buy a Catalyst for 69 Chaos Orbs and sell it for 46 Exalted Orbs when the market is at 45, you'll make a profit on the price difference.Arbitrage opportunitiesReforge Arbitrage: By reforging less valuable catalysts into potentially more valuable ones, players can take advantage of market inefficiencies. If the cost of reforging is lower than the value of the Catalyst you can obtain, this can be a profitable strategy.
Strategic considerationsInventory Management: Players must manage their Catalyst inventory, deciding when to keep Catalysts for personal use and when to sell them based on market trends.Market Research: Using tools such as spreadsheets or community-driven resources can help you understand which Catalysts are currently undervalued or overvalued, allowing you to make better trading decisions.Risk and reward: While trading catalysts is generally less risky than other high-stakes trading, such as unique items or high-level gear, there's still an element of risk, especially with the randomness involved in reforging.Gold cost: Trading often involves a small gold cost for listing items on the exchange or for reforging, which players will need to factor into their trading strategies.

Advanced Techniques

Use of spreadsheets: For serious traders, maintaining or using a community-provided spreadsheet to track catalyst prices, profit margins, and reforging results can optimise trading strategies.Community Engagement: Sharing insights with other players, understanding market trends, and sometimes even forming trading alliances can lead to better deals and information on upcoming shifts in Catalyst demand.
