But this is more than extrapolation--this is just unecesary assumtpions. THat is the key. This isn't rally necessary and at any rate there are much better ways to explain why people can't perform certain spells, that rely much less on unproved assumptions.

 

But those "much better ways" are now nearing the cliche level, and are certainly well worn. IMO its always better to try something new. Its fanfiction, you make itup as you go along, with new things that ain't in canon.

 

Maybe that's what the ICW actually does? Decide on spells to be outlawed over different countries? This would leave each nation with a base number of spells that have to be outlawed, such as the AK, the Cruciactus, etc. But leaves any extraneous spells up to the ruling body.

 

have you taken into consideration spells that are custom made, or made by individuals?? new spells that are created aren't all registered at the ministry making blocking them hard... What do they do when new spells are about to be blocked?? Summon the entire wizarding population to have a new block placed on their wands?? complicated...

The part about the cruciatus curse is good except you might want to add skills in occlumency, since it is a magical skill enabling you to shield your mind from memories, emotions and mental attacks... Skills in occlumency might enable you to cast crucio without going through rituals or being a sociopath.

 

It's an alright idea. They could also implement stuff like having your wand reblocked every 3 years or so so to keep it up to date with newly developed spells. Kinda like how you have to get your drivers liscence renewed every so often.

The only MAJOR crippling point to this idea that I find is you assume people are going to break the blocks on their wands. Why break the blocks, when it will be nearly gauranteed that atleast someone is going to be selling blackmarket wands untampered by the ministry. If your any kind of high ranking death eater im sure you'll have the connections to get one. Or Any pure blood with a long line of inheritence money. Or any low ranking death eater, who now obviously has connections with both the people with high money and high status.

The only people left with the shitty wands are going to be normal law abiding citizens.

Another minor problem is your going to have to develope a VERY extensive and in depth way of keeping track of all magical folk traveling country to country. These are wizards and witches that pop around with portkeys, floo, and apparition. Now some dude riding a bus across the borders or comming by ship.
