We’re gonna break Minstrel skills into five groups: Ballads and Anthems; Healing; Tales; Damage; and Other. While it may seem that healing, as the core role of the Minstrel, should be dealt with first, the fact of the matter is that you can’t be an effective Minstrel by just spamming heals. Obviously you need to do damage solo, and there are too many nice group buffs for you to ignore while in a fellowship.
As a result, whenever you don’t have the pressing concern of healing yourself or a dying fellow (or focusing on damage, see the Damage and Healing sections), you will be working on moving forward your Tiers. Many of your Skills are Ballads (note that some are called Songs but are listed as and function as Ballads in game and here). They are divided into Tiers. Tiers 1 and 2 require an enemy target and do damage to it, while giving you a buff. Tier 3 Ballads don’t need a target or do damage, and provide a buff to the whole group. There is a Trait you can slot that turns your Tier 2 Ballads into group buffs with no damage, but I would only slot it in very specific situations like some raids. The buffs available as you level can make your head spin, including vitality, attack speed, dodge, etc., but definitely use Ballad of Steel a lot for the armour buff, you’ll need it.
Performing a Tier 1 Ballad successfully gives you a few seconds to perform a Tier 2, which opens up Tier 3. Hitting a Tier 3 lets you use an Anthem. Using an Anthem resets your Tier back to 1, but they are nice Skills: a group heal over time, a reduced agro buff, or solid area of effect damage are available as you level. Also note that you can get two if not three Tier 3 Ballads in before firing the Anthem. This is great as Ballad of War should be up as often as possible and depending on your enemy you may also want to use Ballad of Unshakeable Will or Ballad of Flame.
Working through the Tiers seems simple, but remember that if a target resists a Tier 1 or 2 Ballad it won’t open your next Tier. Also, make sure you don’t wake a stunned target with one. Finally, you can only work the Tiers when you aren’t healing.
