How much does it cost nowadays

Seeing as this is more of a question rather than an official request, this is the correct section.
Signatures range based on the artist and, arguably, the quality. However, there are some inconsistencies.
Expect to pay between 500fg-2000fg for a custom signature.
If you’re on a tighter budget, I recommend looking at some artists’ profiles and browsing their premades. Premades are usually a little bit more affordable as it’s not made to specifically cater to YOU.

If you want to put in an official request, please do so here after reading the sticky on guidelines for requesting a signature: https://forums.d2jsp.org/forum.php?f=111
