6/5/26 Update
Removed any suggestion of completing Hracca solo.
Also updated build to obtain Flurry from Teras Kasi allowing the build to continue completing Revanite challenge.

This is my Assist/Buff-Bot Entertainer/GCW Flag Holder, designed to assist my main avatar. Primary role is buff bot, not active gameplay.
Goal of this build is to provide buffs but provide also support.
To obtain GCW Flag Buff you need to reach Captain in either Rebel or Imperial, later you can get the General's Battle Standard which provides all the GCW Flag Buffs.

Overview:
Assist, not to be played as an active gameplay. Run an assist macro, and button smasher macro for abilities.

Content Solo:
Sher Kar - YES (4-7k DPS w/ Damage PuPs and Damage Stance)
Revanite Daily - YES (w/ Tank Stance)
Hracca Daily -NO

Pro:
Provides those sweet Entertainer and GCW Flag Buffs

Con:
Not designed for active gameplay.
Lacks some in demand Entertainer Inspiration Buffs

Expertise: You will note the 1 point in many professions, this is to provide all but the Jedi GCW Flag Buff.

Brawler: Going Two Handed for the Flurry Ability gained in Swordsman. Strength for little more Block Chance and Value and more damage output. Agility provides a variety of defense.

Swordsman: Took Master Swordsman for the higher max damage of Kashyyyk Weapons.

Teras Kasi Artist: Focus here is to improve defense especially Block. Taking Master Teras Kasi gives you Tank Stance providing an additional 15% Damage Decrease to damage received, be sure to obtain Flurry (-20% damage output debuff) it provides the build with necessary Tanking ability. Also you can use Steel Body Jewelry Set pushing Parry and Block even higher.

Doctor: 5 points to get that nice Bacta Ampule which has a fast recovery cooldown.
Note you could save 5 points here and place those 4 points into more Muse for those buffs that may be in more demand.

Smuggler: We want Off The Books Buff which grants 50 Precision, 50 Luck, 6% Damage Decrease (*Does Not Display on stat page). This is the bare minimum number of expertise points used to obtain Off the Books Buff (Junk Dealer Buff).

Entertainer: Just the basics of what is needed for buff tree.

Performer: Just the basics of what is needed for buff tree. I chose Musician side, you could choose Dancer side if that would be your preference.

Muse: Still have the majority of the primary buffs for combat, but there may be something you personally need, consider adjusting or removing some from Doctor.

VERY IMPORTANT
Assassin, Bounty Hunter, Commando, Squad Leader, Artisan: Be sure to add 1 point to these professions to gain all the GCW Flag Buffs except Jedi.
Once you reach your Faction General Rank you can obtain the General's Battle Standard which will give all GCW Flag Buffs.

Preferred Buffs and Gear:
Usual Stacked Buffs - Doctor, Squad Leader, Junk Dealer, Favor of the Elders, Tactical Stim, Lasting Performance, Familiar, Mustafar Injector.
Entertainer Inspiration - 3000 Kinetic, 3000 Energy, 6% Second Chance Heal, 5% Evasion, 240 Luck.
Jewelry Set - Performer (Entertainer Inspiration), Steel Body (Combat)
Attachments - 4 Piece Luck, Stamina, Block Value. 4 Piece Luck, Constitution, Block Value.
Exotics - Critical Hit Reduction, Healing Potency, Weapon Damage.

Final Comments:
I run my Entertainer with less then above since I also wear Embroidered Sash and Reverse Engineering Arm for additional Luck when temporarily switching Expertise to Crafting.
