Code:

sub poison()
var dagger='Your ID here'

while UO.SkillVal('Poisoning') < 1000
UO.FindType(0x0F0A,0x0000,'backpack')
if UO.FindCount() then
UO.WaitTargetObject('finditem',dagger)
UO.UseSkill('Poisoning')
wait(11000)
endif
wend
endsub

Insert ID of you dagger to the variable and thats it.. Also you can try adapting delay to your ping, I made 11 seconds here because thats how it worked for me.
