you can use any or all of them as long as its in that order.
for example above pic :-
HEADSHOT 200 TIMES(200/200)
just change the value 100 to 200
= 200;200;21;100;2::21
-------------------------------------
= 200
is the total value you need to complete for that particular quest.
= 200
which is below it is the current value you had completed.
= 21
is the ID of the event tokens.
change this value to different number to get different item.
= 100
which is below 21 is the quantity.
= 2
which is below 100 is the value that indicate that you had completed and claimed for that particular quest.
change it to 1 and freeze will make you able to claim it over and over again.
