After completing a raid in OSRS, a purple light will appear above the chest if you get a raid unique item and a white light if you receive supplies only. In Alora, the chest always shows a white light, even when you get a raid item (I saw this in several Alora raids video's on Youtube and when I had a raid drop myself). Perhaps this can be implemented to make a raid drop even more exciting?
Let me know what you think :).
