-1 intercept vs +1 stealth.

I don't get the difference between those two since you can have negative intercept.
What's the point to give -1 intercept instead of +1 stealth? What am I missing here?

Somebody has the answer?

Cards that give -1 intercept are usually tied to some conditions (e.g. one single minion, minions lacking a certain trait/discipline or that are allys or younger). Tying stealth to conditions except for playability is somewhat harder to express rules-wise. So functionally they are the same when comparing intercept to stealth, but allow for easier implementation of restrictions.

There is also 2 things to know about -1 intercept vs +1 stealth :

First is the fact that nothing in the rules forbid you to play cards that give -1 intercept to certain category of minion just to cycle a card. So you can bleed with a perfect paragon superior even if nobody wants to block you.

And second (but this is far fetched ^^) there is at least 1 card that set the stealth for an action to a fixed amout :
Name: Draba
[FN:C2]
Cardtype: Action/Reaction
Cost: 1 blood
Discipline: Chimerstry
[chi] +1 stealth action. Put this card on a ready minion. You still control this card. Burn this card to reduce that minion's stealth to 0. The minion may still increase his or her stealth.
[CHI] Reduce the acting minion's stealth to 0. The minion may still increase his or her stealth.

In a number of cases, negative intercept is given to a specific minion or minions - other minions are unaffected. So for example, Call of the Hungry Dead allows you to affect one would-be blocker, without affecting others.

This feeds into the fact that sources of negative intercept can be good for responsible bleeding, if you make sure that your grand-prey isn't affected by the negative intercept, which often they won't be if it's restricted to a particular minion. So unlike going to +2 stealth on a bleed action and then getting bounced and your grand-prey being unhappy they can't block, you can take out blockers with negative intercept without screwing up your grand-prey's ability to block if/when you get bounced.

Also, while negative intercept is sort of like stealth, it isn't stealth. You can cycle negative intercept even if you don't need to - the rules restricting you gaining stealth unnecessarily, they don't restrict you giving someone negative intercept. This can make it slightly easier to cycle, which is a potentially useful fringe benefit.

There's also something to be said for the flavor / theme associated with cards. +Stealth represents the means and methods a vampire is using to remain undetected, conceal their movements, and go unnoticed. Powers like Obfuscate and Obtenebration help with this. But some vampires can and do forego being sneaky and instead just use intimidation, guile, subterfuge, bribes, or perseverance (,,,,,, etc.) to bypass, mislead, or hamper a would-be foe (blocker).

In other words, having intercept as a variable that can be modified with both + and - effects allows for more conceptual (thematic) space and interesting card designs (mechanics).
