I understand the majority of the sentence, however the 段数 part is messing me up. My gut tells me it is talking about ammo, but no matter where I look -online or in multiple dictionaries- it refers to steps, levels or grades.
Right now I have:
"Recover 10% of maximum ammo of the equipped Option Equipment when disconnecting an enemy's part."
Running a google image search is one of the faster, but at times, most inaccurate ways to check the meaning of a word. In your case, I found various stairs, the gears of a bike, graphs and growing tomatoes. All of those images support http://www.alc.co.jp 's definition of 段数 as 'stages', or the number of steps. Breaking the kanji apart, you see 段 which appears in 'staircase' (階段), followed by 数, which is used in the word 'number' (数) and 'math'/'study of numbers' (数学). Ammunition is 単数.
Just make sure you remember that 最大数, 'limit', is also a part of the sentence
There is a fine line between bad and good, and an even finer line between good and great.
Even the most impossible dreams can become possible with time.
Sounds like something from a game to me lol. 段数 is level anyway, and I can see you've treated it 弾数. Do you have more context? What's this "enemy part?"
From the outset, it really does look like a typo. I don't see how you can recover 10% (quantity-wise) of the maximum level of something...
Btw I'm also a bit confused as to whether the first "part" = the second "part." If they were both referring to the same enemy part, then the 'ammo' recovered is applied to that "part?" If you get me...
Thanks for the help. For some reason I never considered that it might be a typo. It turns out that both characters can be typed as "dan," so my instincts were correct about it talking about ammo. Unfortunately, when dealing with games, context isn't always available.
