It looks really cool and fills a niche for me that path of perfection wasnt able to.
For one it fits my concept of an "eye of the storm" thunderstorm themed dragon monk really well.
Heavens Thunder is visually really cool and also perfectly fills a hole of damage oriented monk for me. https://2e.aonprd.com/Feats.aspx?ID=2199
Its a one action ability, reusable that adds electric and sonic damage to unarmed and monk weapon strikes until next turn. I was missing something exactly like this for monk. With Flurry of Blows monks can make two attacks in a single action but since they dont have something to boost MAP (like flurry ranger for example) they generally also dont want to make more attacks. Adding movement to the mix the monk can often have a left over action. One can use that to raise a shield but that is not something that fits my idea of monk personally (and i dont wanna be called a cpt america clone constantly). That is also wy monks gain less from being hasted than other martials since their action economy is so good already. So Heavens Fury is a perfect way for monk to boost damage without raising MAP.
I just love that feat both gameplay and flavour whise.
The problem is its way too f%~#ing strong. It gives a damage bonus bigger than giant barbarian. Seems like most martials would want that. From what i heard it is already on the list for erratas but we know that can take ages.
Is there a way that the feat could be nerfed while still being good for monk? I was thinking either halfing the damage, maybe removing the sonic damage alltogether. Or making it dependent on weapon dice. Adding 1 sonic, 1 electricity per weapon dice, which would result in it being a +4 to damage instead of a +6 and rising slower. Or making it last only until the start of the next turn, not the end of it, so youd have to use it every turn instead of only every other one.
What are your opinions on the archetype? As a gm would you allow it as is? Would you nerf it? Or disallow it alltogether.
