===Thunder Hammer===

Big war hammers (''40k'') that smash anything they touch, and popularly paired with Storm Shields. Unlike other power weapons, Thunder Hammers only activate their energy fields upon contact with a target. This works like a flash capacitor, and utterly ''explodes'' whatever Thunder Hammers hit - in editions [[Dark_Age_of_Technology|long past]] this meant they always scored a wound whenever they hit, no roll was needed. Comes in one-handed and two-handed varieties, but both functionally are the same weapon stat-wise. Particularly common among Terminators, although the [[Salamanders]] love it (going with [[Vulkan]]'s training as a blacksmith and the artificer themes of the Promethean Creed).

Gameplay wise, they're basically the same as Powerfists, except when attacking vehicles they will at a minimum get a "Crew Shaken" if they glance or penetrate, in addition to whatever else they roll on vehicle destruction. From 6th ed onwards, the special effect was changed to the "Concussive" rule; any target that takes a wound (but survives) is reduced to Initiative 1 till the end of the next assault phase, simulating disorientation from the explosive impact, making it very effective even against big gribblies that are tough enough to avoid Instant Death.

Fun fact: Captains could not use thunder hammers without wearing terminator until [[Dawn of War]] proved how [[awesome]] it looked. 8th edition removed the concussive rule and the low Initiative, replacing them with minus 1 to hit 2x str AP3 and 3 damage flat. 9th Edition reworked Thunder Hammers to make them less of an autopick over Power Fists, sacrificing armor penetration in exchange for more damage.
