From Battle of the Immortals Wiki
- A Chalice is a piece of equipment that boosts Physical or Magic attack, and can add other attributes. As the level increases, the bonuses increase.
- A Chalice can be upgraded at Leon in Atlantis Square using Holy Water. Up to level 6, if you fail to upgrade successfully it drops 1 level. Between level 6 and 10, if upgrading fails the Chalice returns to level 0. Finally, if it fails above level 10 the Chalice is destroyed.
- There are 4 different chalices: Bronze Chalice, Silver Chalice, Gold Chalice, and Platinum Chalice. You are automatically awarded a Bronze Chalice from the Supreme Pack at level 60. If you wish to obtain a Silver or Gold Chalice, or your Bronze one breaks, you can make a new one with 1 Medal of Triumph, 3 Diamonds, and 1 Chalice Formula Scroll if you selected the Handicraft research tree. Platinum Chalices require a Recipe of Platinum Chalice, instead of a Chalice Formula Scroll. If you did not choose Handicraft, you can still purchase Chalices from other players.
