Signature Stone Concern
Signature stones are valuable resources that are often saved in my inventory. Normally if I use at least one signature stone I notice an increase in the character's P.I. If after applying a signature stone, and there is no increase or effect at all to the character's P.I, what does this mean? I applied a signature stone to a 5* R4 Phoenix with 160 sig, the P.I was 10,920, and the numbers didn't change. This sometimes happens. It has happened maybe twice to say the least. Has this happen to anyone before? What is the explanation for this by the developers? And where can I find a solution to fix this! Thank you.
