Many of these required a specific monster or a match-5 of the loot gem. Later there will be an accessory that upgrade the rarity of the loot you match, so you only need to make a match-4 for rare loots.
The color of the loot icon will change depending on the number of gems in the match, with bronze for common loots, silver for uncommon loots, and gold for rare loots. I’ll make a tutorial for this part to make it clearer in the future.
