Don't worry, I won't just throw in words, I actually do understand the grammer, and conjugations and such. If you would like, I could get a professional to see if the lines make sense...
Now, by try, do you mean you have a few years of high school spanish, or that you speak the language fluently? The other language versions of the game already suffer from poor voice acting, I understand. I'd hate to foist a poor translation on them, too.
If anyone is able and willing to translate 38 new strings for Ashes of Embers, that'd be great. I need them in the following languages:
German French Spanish
And if you're willing to translate the entire thing into a language of your choice, that offer is still up, too. In total there are around 500 strings, though most of those are item descriptions, and as such you should be able to copy the existing string from your language's dialog.tlk and simply edit as necessary.
