Thanks you for these.
Helped a lot to finish my first Advanced Stage 20 Sand Empire. I needed the Darts and 3* / 4* battle items and ingredients.
Being able to swap in, and swap out, three heroes to fight the mobs and bosses made is faster and less nerve racking.
Rigard and Melendor ran the whole event with Proteus doing most stages without a solo purple boss. Wu Kong, and Jackal, did most of the solo purple boss stages.
Shout out to emblems ( I rage quit before 2018 Sand Empire due to 5* heroes summons rate and 4* ascension item drop rate).
