What are "cursed tables"?
To answer this question, we need to look into the way MH3U appraises your charms. Your charms are pulled off of what is known as a "charm table", a collection of different charms with different specific stats. This system was present in Monster Hunter Tri as well, though less potentially game-breaking (for certain values of "game-breaking").
Unlike in Tri, where a charm table was assigned when you started the game, your charm table is assigned to you at character creation. Once you create a character, that character can only receive charms from the roughly 20,0000 charms present on their specific charm table. Unless, of course, they are assigned a "cursed" charm table.
"Cursed" charm tables possess only ~800 possible charms, dramatically fewer than the 20,000 in a normal charm table. While this may acceptable, or even preferable, if those charm tables had one or more "god-tier" charms, most cursed charm tables have a horrible selection of charms. One table is even devoid of 3-slot charms.
Now, how do you avoid getting a cursed charm table? Luckily, most games are absolute rubbish at approximating randomness, relying an easily manipulated psuedo-random number generator. The specifics are not necessary, but what you want to know is this: What charm table you get can be determined by the time at which you created your character.
Forcing a specfic charm table is acheivable in a few easy steps and only requires a few items.
Items: Your 3DS and MH3U (obviously) and a stopwatch (although this is only strongly recommended unless you have an absolute impeccable sense of time)
- Turn off any wireless connection for your 3DS.
- Set the date to 21/01/2012 and the stopwatch to the appropriate time interval for your chosen charm table.
- As soon as you confirm your date/time change, start your stopwatch.
- Open MH3U and hover over "New Game" (Do not click).
- As soon as the stopwatch confirms the proper time for you, press "New Game".
- ??? (Algorithm magic!)
- You now have a character with the appropriate charm table.
If you already have a character, you can determine your charm table by following this link and the instructions within.
