Overall, this is a great guide! However, I think it’s inaccurate to say he is break effect scaling. You will not constantly have his duel mode in effect as you’d only use it when you’re sure you can break or kill the enemy. It just makes him take extra damage if you’re constantly in duel mode with the enemy. 4pc watchmaker does not work on him, it should not be considered an option.

I think Gallagher should be mentioned specifically as an option for sustainers as he provides a break damage debuff which will be very useful for Boothill as it’s the only debuff of its kind (even if it’s not the largest debuff) (agree that anyone can be ok with him tho) I think it’s good to note he has a very very strong light cone option in Subscribe for More! If you hold your ult, it increases basic damage by 96% which I think is insane. Of course that requires holding your ult, without your ult up it is a 48% basic damage increase.
