Why does he only have 9 skills?
He got a single duplicate (unless "strength" was somehow mistranslated in the same goddamn sentence as "power").
He pulled 11 skills, and has "Gacha" as a skill already.
With a single duplicate, he should have 11 skills; and even if some person translated two identical words next to each other incorrectly, he still should have 10 skills.
Did he lose a skill, somewhere? Or is the writer an idiot?
[EDIT]
I just read that this is your first TL, and it's not bad at all. I have seen much, MUCH worse from people who claimed they were experts.
Keep practicing!
