So i am trying to make a trinket that has a very low chance of blighting on every hit i looked at the stuff for the COM Hilt trinket that does this On Attack Hit: Blight (120% base) 2 pts/rd for 2 rds

so i added this to my effects file
// Grave Robber Sickening Satchel Blight
effect: .name "Sickening Satchel Blight" .target "target" .curio_result_type "negative" .chance 120% .dotPoison 2 .duration 2 .on_hit true .on_miss false .can_apply_on_death true
and this to my trinket file
"attack_skill_additional_effects":
[
"Sickening Satchel Blight"
]
underneath the origin dungeon just like how it looks in the com files and it doesn't work any help would be greatly appreciated
