i've had alot of halfkeys recently, it tends to work if you let them fill your inventory and then awnser all correctly, i've had 10 MOM's in the last two weeks and got at least 4 half keys
at the beggining there wasn't a report abuse, or adamant, hehe i can say i was one of the first 1500 players, but i never trained an account over lvl 40 back then then stopped playing for a year when rs2 came out
