Question Rewarded triggers in some tba rooms

I've noticed a few "reward" triggers in some rooms, and I understand the trigger code and what they do, but I'm confused as to why & when they are trigged.  For example, this one leading to the dumps in Midgaard.  What is the %object%?  Do I need to retrieve something to get rewarded?  Oh, and what is the 2 h 100?  I think 2 means "world", but unsure of the other 2 arguments.

#3004
Dump - 3030~
2 h 100
~
%send% %actor% You are awarded for outstanding performance.
%echoaround% %actor% %actor.name% has been awarded for being a good citizen.
eval value %object.cost% / 10
...

end
if %actor.level% < 3
nop %actor.exp(%value%)%

Thanks @Rumble

The keyword "drop" is what I needed! TSTAT here I come!
