            <passive_effect name="LootDropProb" operation="perc_add" value="100"/><!--YYTip：base_setIt will cause an error message of no drop, and a red text will pop up. 100 means the drop rate is increased by 100 times. If the drop rate is 0.001, multiplied by 100 is 10%, so a 100-fold drop rate is not a 100% drop rate.
