Havent they only increased it to 30 points per defeat last year, despite having to have dragonflame thing to access the brooding grounds?
I could only play so much before I became exhausted, and having to craft both energy and the dragonflane things made me get bored more quickly, because it is really tedious to do when you do not have all crafting slots unlocked (I then had and still have only 10 of them unlocked).

Correct me if Im wrong (which I probably am considering I havent played the Halloween event in 2021 and 2020, but I do not think they increased the points for halloween bosses this year despite 1 week duration for each reset.
