I would change the name, leaving only "Traps" or "Trap Proficiency", following the same reasons for which the Martial Arts page isn't called "Martial Arts Mastery" and the proposals on the
on-going revision of Stealth Mastery
I find this bit a little pointless, since it covers only a few of the many instances where traps are either particularly useful or uneffective. Also, rage powers doesn't necessarily mean the user goes berserk:
This ability is very effective against characters who are not very intelligent or who get carried away a lot by their emotions or instincts (at a lower level, since the Instinctive Reaction ability can constrict it) such as those with the ability Berseck Mode or Rage power.
The page should make mention of characters who create traps via superpowers. Currently, the page seemingly only covers those who make them via preparation or equipment.
For example, we have Goku making a
mine field with ki, Granolah
detonating a bunch of debris (a few pages after the beginning of the chapter), several wizards across fiction creating grass knots, brambles and more, Pokémon moves such as
Stealth Rock,
Toxic Spikes, ten thousand of stands from Jojo which focus on traps and deceive etc..
It could also mention that traps can also be physical attacks or part of someone's combat ingenuity, see Kakashi's
Headhunter Jutsu, Buggy
faking his death to stab Zoro or hidden weapons meant to active or be unsheathed the moment the opponent is close enough, and so on with more cases.
