As others have stated I'd probably go for the wings I guess since that's the source of their magical powers
.
Then again this is where things get complicated
. First I need to attack/ambush the fairy when it's still in human or preferably a much smaller size or it's pretty much GAME OVER
since a giantess fairy will not automatically get smaller as a result of damaging her wings and simply stay at that height untill they're healed off completely.
Second their predator sense could most likely turn out to be the biggest problem here since it will tell the fairy that humans are nearby if my plan is to prepare a trap and calmly wait for it to strike from where I can get a good overview to see if things have worked out
.
Then again I doubt setting up something that is more effective (so I can leave the danger zone and won't have to keep an eye on it) will help much either
(apart from ensuring my own safety
) since fairies like Lucilya, Subeta or Melany probably wouldn't fall for it and detect human traces right away due to the fact that (unlike me) they're used to the area as native beings
.
