Add a variable "DateTime" called PrestigeBuff on Character.cs too
With this you can do whatever you want, add more prestiges or more buffs on each prestige.
Code:
if (PrestigeBuff.AddSeconds(2) <= DateTime.Now)
{
PrestigeBuff = DateTime.Now;
switch (PrestigeLevel) {
case 1:
AddBuff(new Buff(3000, Level), true);
break;
case 2:
AddBuff(new Buff(3001, Level), true);
break;
case 3:
AddBuff(new Buff(3002, Level), true);
break;
}
}
