Hello adventurers, I have a question about leveling mercenaries. What do I need to level my mercenary?
If you open up your menu and go to mercenaries there should be an icon to click on that lets you manage their gear. Towards the bottom you will have the option to start training/level them which is basically a waiting game. If you do overseer quests and dailies at higher level you will have a chance to get time reducers for their training. Hope that helps
The icon Doomey is referecing is a large blue square at the top of the merc screen when you bring them up. I had to add this as I nearly lost my mind trying to figure out how to level and gear my merc waaaaay back when they were a new thing.
