Pros:

The main strength of the Vaal Burning Arrow build lies in its shotgun-style AOE damage, which is capable of obliterating packs of monsters in a single shot. The Soul Ripper flask enables Vaal Burning Arrow to gain a high degree of power and consistency, as it provides a large amount of additional soul charges. This allows Vaal Burning Arrow to hit harder and more often, making it an excellent choice for clearing maps. The Nemesis mod adds an additional layer of powerful shotgun-style AOE damage, making it an excellent choice for single target fights.

Cons:

The Vaal Burning Arrow build also has some weaknesses. The main weakness is the lack of attack speed. Vaal Burning Arrow is limited by soul gain prevention and soul generation, meaning that it is not limited by attack speed. This means that it can take a while to kill packs of monsters or bosses. Additionally, the lack of attack speed can be an issue when playing the build as a dead eye.

To use Vaal Burning Arrow sustainably, you need to generate Flash Charges and Souls. Flash Charges can be generated through the use of Chests Pieces, which give two Flash Charges per three seconds, the Master Mind node, which gives one Flash Charge per three seconds, and the Pathfinder Jewel, which gives three Flash Charges per three seconds. You can also get Flash Charge Gain from a Cluster Jewel and a Belt. On top of all of this, you can use Bael for an extra Flash Charge. 

Souls can be generated through the use of Soul Ripper flasks. Ideally, you want to spend exactly 45 Flash Charges for the maximum number of souls. Soul Ripper flasks can also be stacked for more charge generation. For example, if you have two Soul Ripper flasks, you can get twice the soul generation. 

Finally, the character build is a Deck Stacker. The idea is to stack a lot of Flash Charges and Soul Rippers to sustain Vaal Burning Arrow. The Deck Stacker build is not necessarily the optimal way to play this character, but it is a fun way to play. You can also opt for more optimised builds, such as using three Soul Rippers instead of Bael. 

Overall, the Vaal Burning Arrow is an exciting and powerful build for Path of Exile players. It utilizes the unique capabilities of the Vaal Burning Arrow skill to achieve excellent results in both single target and clearing scenarios. The build also takes advantage of the Nemesis mod, which adds an additional layer of powerful shotgun-style AOE damage. The main strength of the Vaal Burning Arrow build lies in its shotgun-style AOE damage, which is capable of obliterating packs of monsters in a single shot. However, the build does have some weaknesses, such as the lack of attack speed and the requirement for expensive Poe Items. Despite these weaknesses, the Vaal Burning Arrow build is still an excellent choice for players who want to experience the powerful shotgun-style AOE damage of Vaal Burning Arrow.
