What is the best artifact set for a support Bennett in the Spiral Abyss in Genshin Impact?

The best artifact set for a support Bennett in the Spiral Abyss is the Noblesse Oblige set. This set is highly effective for Bennett because it enhances his support capabilities, particularly his Elemental Burst, which is the core of his utility in any team. Bennett's Elemental Burst, Fantastic Voyage, provides a significant attack boost to all party members within its radius and heals them based on Bennett's maximum HP. The Noblesse Oblige set complements this by increasing Bennett's Elemental Burst damage by 20% and, more importantly, granting all party members a 20% attack boost for 12 seconds after using his Elemental Burst. This makes Bennett an invaluable asset in the Spiral Abyss, where maximizing damage output and sustaining your team are critical.

To optimize Bennett for the Spiral Abyss, you should focus on building him with high Energy Recharge and HP. Energy Recharge ensures that Bennett can use his Elemental Burst frequently, which is essential for maintaining the attack buff and healing. HP is important because Bennett's healing scales with his maximum HP, so the more HP he has, the more he can heal your team. The main stats you should aim for on your artifacts are HP% for the Sands, HP% or Pyro Damage Bonus for the Goblet, and Healing Bonus or HP% for the Circlet. Sub-stats should prioritize Energy Recharge, HP%, and flat HP.

For weapons, the best choice for Bennett is a high base attack weapon, as his attack buff scales with his base attack (which includes his weapon's base attack and his character level). The best 5-star weapon for Bennett is the Aquila Favonia, which has a high base attack and provides additional physical damage. For 4-star options, the Festering Desire is an excellent choice, as it provides Energy Recharge and increases Elemental Skill damage, which can be useful for Bennett's Elemental Skill, Passion Overload. Another good 4-star option is the Sacrificial Sword, which can help with Energy Recharge and potentially reset the cooldown of Bennett's Elemental Skill.

In terms of team composition, Bennett works well in almost any team due to his versatile support abilities. However, he is particularly effective in teams that rely on attack buffs and healing. For example, in a team with Diluc or Hu Tao as the main DPS, Bennett can provide the necessary attack boost and healing to keep the team alive and maximize damage output. In a team with Xiangling as the main DPS, Bennett can also act as a battery, generating Pyro particles to help Xiangling recharge her Elemental Burst more quickly.

One common mistake to avoid when building Bennett is neglecting his Energy Recharge. Without sufficient Energy Recharge, Bennett will struggle to use his Elemental Burst consistently, which can significantly reduce his effectiveness as a support. Another mistake is focusing too much on attack stats, as Bennett's attack buff only scales with his base attack, not his total attack. Therefore, stacking attack artifacts or weapons will not increase the attack buff provided by his Elemental Burst.

Advanced techniques for using Bennett in the Spiral Abyss include timing his Elemental Burst to coincide with your main DPS's burst window. For example, if you are using a character like Childe or Ayaka, who have powerful Elemental Bursts, you should use Bennett's Elemental Burst just before activating theirs to maximize their damage output. Additionally, you can use Bennett's Elemental Skill to generate Pyro particles and funnel them to your main DPS, ensuring they have enough energy to use their abilities.

In specific scenarios, such as facing enemies with high Pyro resistance, you may need to adjust your strategy. For example, if you are fighting a Pyro Hypostasis or a Pyro Abyss Mage, Bennett's Pyro damage will be less effective. In these cases, you can focus more on his healing and attack buff capabilities rather than his damage output. You can also pair Bennett with characters who can apply other elements, such as Hydro or Cryo, to trigger elemental reactions like Vaporize or Melt, which can help overcome the enemy's resistance.

Overall, building Bennett with the Noblesse Oblige set, focusing on Energy Recharge and HP, and using a high base attack weapon will make him an incredibly powerful support character in the Spiral Abyss. By carefully managing his Elemental Burst and coordinating with your team, you can maximize his potential and significantly improve your performance in the Spiral Abyss.
