If you are the hero that does the final damaging blow to kill a creep (called the last hit),
ラストヒットを取れば、
ゴールドを獲る。
If you do not get the last hit, you only get experience, assuming that you are close enough.
ラストヒットを取らなければ、遠くにいない限り経験値を得るのみである。
This is the first thing that you will have to practice to become a better than average Dota player.
