 It should be noted that 광부 의 커피 can be placed into herbalism bags such as 하이 잘 원정대 가방 , oddly enough .

 광부 의 커피 has a sell price and stacks to 20 . It ' s buff 광부 의 커피 adds 20 % to your run speed while in the mine , and stacks up to 5 times for a total of an additional 100 %. The 광부 의 커피 buff lasts 3 minutes ( not long enough to finish your mining ) . 
 잘 보존 된 채광 용 곡괭이 has a sell price and stacks to 20 . It ' s buff 잘 보존 된 채광 용 곡괭이 reduces your cast time ( channeling ) while mining a node to 1 . 5 seconds ( down from 3 seconds ) . 
 The 잘 보존 된 채광 용 곡괭이 and 일 꾼 의 채광 용 곡괭이 now stack ( as of 6 . 1 ) and reduce your channeling time to a negligent . 2 seconds . .. basically immediate . The time for ( SHFT + Click ) auto - looting takes much longer than the mining itself . 
 Using more than one of these not only adds stacks of 광부 의 커피 , but it also refreshes the timer . So if you ' re having trouble getting through in 3 minutes , wait a bit to use your last one . 
 As of Patch 6 . 1 광부 의 커피 is reduced from a five minute to a 3 minute duration and also stacks in lots of 20 in your bags . The good news is this item stacks speed buff . If you drink one you get a 20 % increase in speed , drink 2 you get 40 % speed increase , drink 3 you get 60 % ( stacking up tp 100 % max ) . To date I ' ve found drinking three gives you enough speed to get through a level three mine and out the front door in less than three minutes . Oddly Blizzard increased the duration of the 채광 용 곡괭이 to ten minutes and it doesn ' t stack for buff which makes no sense at all since it doesn ' t stack on buff . Would be better if they let it stack to ensure you only have to do one stroke on the nodes . 
 광부 의 커피 and 잘 보존 된 채광 용 곡괭이 drop from Mine Carts in your 달빛 내림 발굴지 / 서리 방벽 광산 레벨 2 or 달빛 내림 발굴지 / 서리 방벽 광산 레벨 3 . 
 PRIOR to 6 . 1 광부 의 커피 : 
 1 . Equal Opportunity to drop between 광부 의 커피 and 잘 보존 된 채광 용 곡괭이 . 
 5 . The 광부 의 커피 buff lasted 10 minutes and would not stack . 
 AFTER to 6 . 1 광부 의 커피 : 
 1 . Three times more likely to drop ( than 잘 보존 된 채광 용 곡괭이 ) . 
 5 . The 광부 의 커피 buff lasts 3 minutes ( down from 10 ) and stacks up to 5 times for a maximum of 100 % increase ( 5 x 20 %). 
 Using 광부 의 커피 to stack will refresh the timer on all existing buffs . If you use the item 30 seconds prior to the first 광부 의 커피 buff expiring , you will gain a second 광부 의 커피 buff and have a + 40 % speed buff for 3 minutes . .. and so on up to 5 stacks and a + 100 % speed buff . The 광부 의 커피 buff does stack with class speed enhancements , such as the 사냥 꾼 , and other class related movement forms , such as the 주술사 늑대 정령 . 
 On my rogue , when I go into stealth ( for the 밤 추적자 speed boost ) it removes the coffee buff . Is that supposed to happen ? I haven ' t seen any other comments mention it .
