Too much work energy drained

Greetings everyone.

“Relic Search” states that it consumes 62 “Life Energy” upon digging.

Now first of all, one time it’s called “Life Energy”, another time it’s called “Work Energy”.
That’s a bit confusing.

But nonetheless, when I activate any amount of Leap Essence it should theoretically drain exactly 124 Life/Work Energy per digging, while in fact it drains exactly 360 Life/Work Energy.
Now what tooltip is wrong? Relic Search or Leap Essence?
