Not much, I would just NOT doompost next time knowing that does almost nothing but getting your posts mass flagged by people that hate your guts. Even if there is valid reason for frustration.
found out during the event that you could sell 1 of each halloween seasonal to an npc merchant, buy them back on another account, then find any random halloween seasonal to have the check if you ‘completed’ the event. boom, free headless in 5 minutes and maybe a thousand crowns spent rebuying.
unfortunately i had a consciousness and felt like it was cheating, so i only did it twice to double check then stopped, leaving me with 4 headless heads (2 painstakingly legit)
