Powerful, but Inaccurate

In the spirit of Competitive Balance, there has to be a drawback for everything. In this case, it means that a powerful attack is more likely to miss it's mark than a weaker one. Now, the reasoning behind this can vary wildly; ranging from discouraging the usage of a particularly powerful move to simply encouraging people to try something else. But sometimes, this trope can be driven to the point where one's Improbable Aiming Skills can't provide a remote opportunity of landing an otherwise fatal hit. *cough* Fire Emblem *cough*

For clarity, as an sub-trope of Necessary Drawback, this trope counts if an weapon or attack has an noticeably high probably of missing and is stronger than most of your arsenal. If it's solely the fault of the user, blame them for graduating from the Imperial Stormtrooper Marksmanship Academy. A-Team Firing is when this applies to everyone wielding the local equivalent of a rocket launcher. Awesome but Impractical is related to this if a more accurate and weaker attack turned out to be more reliable.

This is also related to Difficult but Awesome when the Random Number God is actively working against you and you're winning behind this. Fixed Forward-Facing Weapon is when your your accuracy is affected by the direction your weapons are facing. And Always-Accurate Attack is the opposite of this when your attacks are weaker than usual in exchange for a guaranteed hit.

Video Games

 * Dragon Quest:
 * Fire Emblem:
 * Generally speaking, the stronger a weapon is, the less accurate it becomes.
 * And compared to swords and lances, axes are slightly less accurate, but they're more powerful.
 * World of Tanks:
 * SPGs (self-propelled guns) are prone to missing by an wide margin, on account of their shells harmlessly landing in front or behind their targets. But when they directly hit an tank from a favourable angle, the results can range from Scratch Damage, simply taking a sizeable chunk out of a vehicle's health, killing a tank with one hit, and even a One-Hit Kill or One-Hit Polykill.
 * While there are many tanks that can equip a canon that fits this archetype, the KV-2 with the 152mm M-10T howitzer is infamous for: Shooting at the ground in front of an enemy tank who's 50 meters away from you, destroying most of the opposition it sees with a single high-explosive shell, severely crippling an enemy tank when said shell doesn't completely penetrates (which is common), and completely missing an nearby enemy only to kill another one that's a fair distance behind it.
