Once players unlock Lost Ark's Stronghold, they will have access to the various facilities on the island. These allow players to craft items, research new projects and upgrades, and more. Most of these will take real-life time, but players can speed things up using the Complete Now and Time Reduction options.
To use the Complete Now and Time Reduction options, players must go to Management Mode in their Stronghold. Then they must navigate to the item they are crafting, research project, or underway mission. At the right of this menu, players can select either option and confirm their choice.
What do Complete Now and Time Reduction do in Lost Ark?
Both the Complete Now and Time Reduction options will reduce the time it takes to complete a task. Using the Complete Now option requires Crystal, but it completes the task immediately. Selecting the Time Reduction option will lower the time and requires a Crafting Acceleration Chip.
These are both great options if you are pressed for time and need to complete a task quickly. You can see how much Crystal is required when clicking the option and using multiple Crafting Acceleration Chips on a single task. Decide what's best for you, and proceed!
