When it's the turn where Yukong gains "Roaring Bowstrings" by using Skill, "Roaring Bowstrings" will not be removed.

If "Roaring Bowstrings" is active on Yukong when her Ultimate is used, additionally increases all allies' CRIT Rate by 21%–29.4% and CRIT DMG by 39%–70.2%. At the same time, deals Imaginary DMG equal to 228%–410.4% of Yukong's ATK to a single enemy.

Talent - Seven Layers, One Arrow

Basic ATK additionally deals Imaginary DMG equal to 40%–88% of Yukong's ATK, and increases the Toughness Reduction of this attack by 100%. This effect can be triggered again after 1 turn(s).

Yukong can resist 1 debuff application for 1 time. This effect can be triggered again in 2 turn(s).

Ascension 4 - Bowmaster

Ascension 6 - Majestas

When "Roaring Bowstrings" is active, Yukong regenerates 2 additional Energy every time an ally takes action.

TLDR

Yukong has a lot of pros for a 4-star character (even more at E6), but it comes with one important con; she's really hard to build/play due to her buff mechanic and is also SP negative to the team.

First of all, let's talk about her Skill. Using Yukong's Skill, she will generate 2 stacks of Roaring Bowstrings to herself. When she has those stacks, the team will get an ATK bonus. This is easy enough to understand.

Roaring Bowstrings will lose 1 stack of it for each ally's turn and NOT action. This means that using Ultimate or triggering follow-up attacks won't make it lose 1 stack of Roaring Bowstrings and will fully benefit from the buffs provided.

Now for the Ultimate. If there is AT LEAST 1 STACK OF ROARING BOWSTRINGS, her Ultimate will increase the team's Crit Rate and Crit DMG, while also dealing some big Imaginary DMG. If she does NOT HAVE any Roaring Bowstrings, this Ultimate will only deal damage but not provide any buff. Yeah, caps lock because it's really important.
In short, if you want to use her Ultimate to get that sweet Crit Rate and DMG, make sure to use her Skill first before using Ultimate (you don't have to IF you have 1 stack of Roaring Bowstrings or you have her E6). Otherwise, it will really be a waste of Energy. This is why I mentioned that she is considered SP negative; as she constantly need to use Skill Point to get those buffs.

Team Recommendations

Basic Team for F2P / Premium

Yukong is an amazing support character (even better at E6). If you use 'But the Battle Isn't Over' or 'Past and Future,' you need to build Yukong to have her SPD just before your Main DPS so they can get the ATK buff from her Skill. But if you use LC like Planetary Rendezvous, it is much more reliable as it does not have any specific condition and is always active (although only if your Main DPS is Imaginary type).
Yukong: Buffer
Clara / Seele / Dan Heng Imbibitor Lunae: Main DPS
Welt / Silver Wolf / Other Harmony or debuffer character: Buffer / Debuffer
Luocha or any other healer and shielder: Healer / Shielder

Eidolons

Best Eidolons: E2 & E6

E1: Aerial Marshal
At the start of battle, increases the SPD of all allies by 10% for 2 turn(s).

E2: Skyward Command ⭐
When any ally's current energy is equal to its energy limit, Yukong regenerates an additional 5 energy. This effect can only be triggered once for each ally. The trigger count is reset after Yukong casts her Ultimate.

E3: Torrential Fusillade
Skill Lv. +2, up to a maximum of Lv. 15. Basic ATK Lv. +1, up to a maximum of Lv. 10.

E4: Zephyrean Echoes

E6: Bowstring Thunderclap ⭐
When Yukong uses her Ultimate, she immediately gains 1 stack(s) of "Roaring Bowstrings."

Note: When a E6 Yukong uses her Ultimate without any Roaring Bowstrings stack, it will provide 1 Roaring Bowstrings stack right before the attack, meaning that the Roaring Bowstrings created in such way will provide all the ATK, CRIT Rate and CRIT DMG buff.
