well, I found it :) if anyone is interested
take MapObjects\Inferno\Deleb.(AdvMapHeroShared).xdb and replace Model, AnimSet, HeroCharacterArena, HeroCharacterAdventure, HeroIndividualCamer, CombatVisual with what is specified in MapObjects\Inferno\Biara.(AdvMapHeroShared).xdb
I also changed ObjectRecordID, but it seems to me that this is unnecessary, however, it works :)
