These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Game Breaker: Poison Drop, which lowers all stats of the target. Insanely useful and it doesn't wear off to boot, beware of enemies with the ability to use this as one or two casts can make a character useless. Considering the time limit that each battle has this skills power may be justified though.
Obvious Beta: Towards the end of the game the storyline is obviously rushed.
