Hello! I'm new to FFXI and charting out how to build my character. Since I'm coming directly from XIV I would like to try something that's just not possible in that game, and would like to at least try to build my character as a designated debuffer. That said, this game is quite old and I have no idea what the buff/debuff limit is for enemies and if this may cause issues.

If one were to make a dark knight/black mage, how many of their absorb or elemental debuffs would actually be able to affect enemies at a time? From some cursory research I know that Dia and Bio overwrite each other, but I'm more worried that in a setting with five or so players an enemy may reach a point where negative effects stop applying to them altogether rather than just being incompatible with other players' applied effects. I know that this is probably very niche knowledge and I won't have to worry about it for quite a while but I may shift gears and build towards something else if the game doesn't really support this type of role.
