Conditions with Items

Is there a way you can make a trigger where it checks the number of items you have in your inventory? I need it to check if the hero carries 2 Wands of Negation it will research the first priest ability for you
thnx in advance


EDIT: Oops I thought this was a folder for learning nerw triggers my bad :/ can you move this too

NP, moved..

As for your question..

Action

Actions
for each interger A do If (item type of item in slot Interger A is of type Wand of Negation) then do (set varible(counter) = Arithmatic(counter +1) ) else do Nothing
If (interger comparison)Counter is = to or > 2) then do (action) (else do nothing)
