Both are the same gem, in my inventory on the left, in a trap on the right. Look at the mana leech values. 10 digits, 13 digits.
Am I just being stupid and missing something, or is the trap really multiplying my mana leech by several hundred? With a handful of these gems in traps (most have +30% from barrage), I'm getting 2-3 e15 mana per frame, which seems to indicate that the displayed trap value is correct.
That's a display bug that has been around since the game was released. Basically, for specials, it reads two E levels higher than the actual amount. That right hand gem, the one in the trap, is actually at 2.17e10, not 2.17e12.
Wait, are you guys sure? 2-3 E15 yes? Base 2.17E10, 714 max hits per shot, max 2 shots per frame is 3.098E13. Um...+2Es = 3.098E15, right in line with his estimate of mana/frame. Could the bug be that until E values, all mana gains are actually multiplied by 100x????!!!!
No, they're right. I didn't end up getting 100x more mana next time I got my mana. (Except not all specials have this bug, only the ones that display 2 digits past the decimal point. Which all the useful ones do.)
