Increase party defense or decrease enemy defense

which is more important i you can only have one in your
team? also does anyone know if guild down overlaps
with incr/decr enemy atk def? do the work together or
just work once?

thanks!!!!

excellent question on the guild down/DED interaction. as for the other, i would say it depends on your agility level. If you are going to strike first DED would be more important, such as in an impule A+ demon team, but if you are going to get hit first, you would want your defense raised so that you are more likely to survive and bite back

afaik, guild down and species down stack with the other passive abilities.
