There isn’t a “ranged” build. Mistweaver is a melee spec and always has been. Our strength comes from the fact that we can float in ranged for a little bit if we need to but you should be in melee a majority of the time. If you want to get into Mistweaver I highly recommend you play it the correct way.
Talents: Mist Wrap (Chi Burst only if you’re playing NF), Tiger’s Lust, Mana Tea, Ring of Peace, Diffuse Magic (or Dampen Harm, key dependent), Invoke Chi-ji, and Rising Mist
Stats: Intellect → Crit (to ~25-30%) → Vers → Haste (~15-33% to preference, do not pass 33% as it messes with the AI from Fallen Order) → Mastery
Legendary: Ancient Teachings of the Monastery, this is really the only one you should be using.
Covenant: Venthyr or NF, but I don’t really recommend NF to people unless they’re experienced with the class and are trying to squeeze out as much damage as possible.
Basics:
Soothing Mist: Use this only when you need to do more than 1 spell on a single target, or if you need to use Enveloping Mist (depending on your haste) and a Vivify or more on a single target. Be careful of blowing through your mana with this. Think of this as more of a tool than actual healing.
Renewing Mist: Keep 1-2 out at all times, they do jump around so just apply it to whoever could use a gusts proc, or if everyone is topped, your tank and then a ranged. Targets healed with Vivify will also be healed for a portion when Renewing Mists is active on the target. This is a HOT that gets extended with Rising Mist. This will likely be one of your top 5 healing abilities overall.
Vivify: This will likely be one of your top 5 healing abilities overall. Utilize Vivify for both single target healing and working with the cleave from Renewing Mist.
Enveloping Mist: Use this to focus single target healing when they’re taking heavy damage, also make sure you’re using this to proc your Yu’lon or Chi-Ji’s Enveloping Breaths.
Essence Font: You’re going to be using this ability for either prepping for aoe damage or triggering Ancient Teachings of the Monastery. You don’t really use this for the healing that it gives but more so the HOT that it gives as it procs an extra gust when healed with an ability that normally procs it. This ability will be a bit lower on your overall abilities for the dungeon in terms of healing done but the Gust value will outweigh the actual healing. (If you’re Night Fae this will be higher).
Gusts of Mist: This is your Mastery at work. The higher Mastery you run, the more you’ll see the impact of this ability. It is applied via Renewing Mist, Enveloping Mist, Vivify, and Revival. Depending on your Mastery, this ability will likely be 5 through 8 of your top healing abilities (not including Gusts from Chi-Ji/Yu’lon).
And then your ATotM has 2 events recorded in details/logs and added together (crits and non crits) should be your highest overall most of the time.
