Genshin Impact: Should You C6 Bennett or Not (& Why)?

Raising Bennett’s Constellation level to C6 in can be a bit controversial. The game by HoYoverse offers a wide roster of characters that can be made stronger through Constellation upgrades – these can be obtained when players get the same character from gacha banners or events after they have already unlocked the playable hero. Despite being a free-to-play character, the Mondstadtian is versatile and can be used as a healer, an elemental enabler, and even a sub-DPS for some. His set of skills is very particular, and no other characters match him. Bennett's usefulness even tends to surpass many of his 5-star counterparts.

The founder (and only member) of Benny’s Adventure Team walks hand-in-hand with bad luck and peril but, in spite of this, players still consider him to be ’s best 4-star character, even among dozens of heroes on that same rarity level. There are those who argue, however, that when Bennett has his Constellation increased to C6, most of his potential is thrown away. That is said because of a very specific skill he gains at that level – one that is capable of ruining entire team comps with him in it.

At C6, Bennett gains a few new attributes that allegedly help him and the team on the battlefield. Though his previous Constellation levels grant him more power and increase his Elemental Skill, Burst, and the maximum upgrade caps of these abilities, C6 Bennett in is quite different. This Constellation level grants a 15% Pyro Damage Bonus to all Sword, Claymore, or Polearm-wielding characters inside the field generated by the Elemental Burst, Fantastic Voyage. The main downside, however, is that their weapons get infused with Pyro, which can get in the way of the most important part of gameplay, depending on the team comp.

With it, a C6 Bennett is simply not fit for ’s National Team Build. At this level, whenever he uses his Elemental Burst, he makes it tough for melee weapon characters to trigger Elemental Reactions since their weapons are already infused
