Badges in Dark Souls 3 are icons that players earn from competing in the Hollow Arena. The Badge will change depending on the honor or rank that the player have achieved in the arena. There are 2 different badges, Duel Honor for the 1v1 duels and Brawl/Co-op Match Honor for the Brawls and Co-op matches.
The Badges will be show besides the name of the phantom when summoned into another world (Even for co-op or invasions) and can be seen in the right corner of the Undead Match menu in the Firelink Shrine Bonfire after adquiring and burning the Champion's Bones.
The arena rank system is currently uncertain, because some players have reported been promoted with less wins, or been demoted with just a few losses. Further testing needed.
Currently, there are four know honor ranks: Iron, Bronze, Silver and Gold. Test have shown that you need 5 wins for the Iron Honor Badge, and then 10 wins for every rank after. Consecutive losses will lead to a rank demotion. Your victories are counted as postives and your losses as negatives. If you are at a Gold rank with 35 kills and then lose the next 10, it will drop your wins down to 25, subsequently demoting you from your Gold Rank to Silver. If you are demoted, you can still regain your previous rank by winning the required number of matches to ascertain the next rank. Of course, any losses in the time in which you are attepting to rank up will increase the total number of matches needed to rank up.
