Final Stardust aims to bring a new perspective to turn-based battle systems by introducing many new features such as Saiments, Synergies, Turn Effects, Dynamic Music, Voice Acting and more! 

Saiments = cards that replace items during battle(RNG based). 
Synergies = stronger spells that rely on getting stacks. 
Turn Effects = random effects that happen once every 5 turns. 
Dynamic Music = battle themes changing depending on the situation.
Etc..
