Quick Answer
Answer first
Mercenaries are companion helpers. The official wiki describes three mercenary types - Knight, Archer, and Magister - and says only one mercenary can be active at a time.
Current Season 10 community guides report recruiting them from act towns: Knight in Act 1 Town of Inoya, Archer in Act 3 Village of Mos'Arathim, and Magister in Act 6 Dawn's Chapel, with Gar Nor acting as the mercenary NPC flow.
Use mercenaries for support, extra damage, survivability tools, and utility such as Magic Find, but do not copy old aura numbers or passive values without checking the current client.
System Role
What mercenaries do
A mercenary follows your character as a helper rather than replacing your build. The stable high-level rules are simple: you choose one active mercenary, that mercenary has its own type and setup, and its value depends heavily on whether it survives current content.
The official wiki says mercenary Magic Find directly benefits the player. Community Season 10 guides also emphasize that a mercenary can help with early damage, toughness, utility, and farming efficiency when it is geared properly.
Recruitment
Where to recruit one
- Community Season 10 guides place Knight recruitment in Act 1 Town of Inoya.
- They place Archer recruitment in Act 3 Village of Mos'Arathim.
- They place Magister recruitment in Act 6 Dawn's Chapel.
- If those NPCs are not visible, check your current act progression, town NPCs, and whether the guide's screenshot matches the current patch.
Current Use
How to use a mercenary well
- Keep one active mercenary and choose the type that complements your build instead of duplicating what you already do well.
- Gear the mercenary for survival before expecting it to carry damage in later difficulties.
- Use utility and Magic Find deliberately, because the official wiki says mercenary Magic Find benefits the player.
- Expect revive costs or downtime if the mercenary dies. Community guides currently describe gold-based revive friction.
- Patch notes fixed aura-related behavior after Season 10 launch, so be wary of pre-hotfix multiplayer aura complaints.
What To Verify
Mechanics that are patch-sensitive
- Exact aura values and passive numbers.
- Current gear slot behavior and whether old gear advice still matches the UI.
- Death, revive, and cost behavior at your difficulty.
- Whether an aura works the same way in solo and multiplayer after the latest hotfixes.
Common Mistakes
New-player mercenary mistakes
The biggest mistake is treating the mercenary as a permanent damage solution while leaving it undergeared. In Season 10, aggressive monster behavior and higher difficulty scaling make survivability matter quickly.
The second mistake is copying a specific aura setup from an old guide without checking whether the current UI, passive text, and multiplayer behavior match.
Decision Guide
Which mercenary should you try first?
Need ranged support
Try Archer once the Act 3 recruitment route is available.
Need utility or spell support
Check Magister in the Act 6 route, then verify its passive text in-game.
