Hi all, as of today's commit (https://github.com/rathena/rathena/commit/d3cc0c56563769aafd78c976d6e76d83dbf6df88) rAthena will include the pre-renewal jRO Brasilis monster values in YAML format.
If you want to use the bRO values instead (lower ATK), I've attached a YAML file in the original post to overwrite these.
I also corrected the ATK values for jRO in my original release as they were just guessed before and now they use the official values (but that release only works for rAthena 2013-2016).
