Here's the best example of ups and downs of this perk in action: http://www.youtube.com/watch?v=e8KdmTtoHtE

What it does is basically causing a small explosion around every killed enemy if you drop him with an energy weapon. If this explosion kills a guy next to him, it will cause another explosion often letting you nuke a whole room or pack of baddies.

It can add a lot of damage to energy weapons, but it can also make them unusable in combat where there are friendlies nearby - and it can send you flying a few times if you kill at too close a range making it a hard pick for combating deathclaws or cazadores who are on top of you very quickly (but at the same time if you can hit one well with Gauss and others are close, there won't be many running your way).

So... what say you? Good or bad? Take it or leave it? Should every energy build have this or should it be avoided like STDs?

If you're pure energy weapons, you might not want it just in case the enemy gets too close. But if you're a stealth EW user, it's awesome. You can literally take out an entire group of people with one shot.

If you do it right EW out damage guns per shot (though use lots more energy packs).

Meltdown is fun when you see a bunch of Cazadon and one YCS destroy them all; but if you are fighting close up you are wasting stimpacks.

I say no-no in hardcoe and so-so in normal.

It would be great if you could choose one or two weapons that the perk would be active on (dreaming). Cause I really wanna have this perk but at the same time I use the RCW at close range alot.

I'd expect it to work for example only on plasma weapons. Gauss or flamer setting this off is kind of weird...

Bad perk if you have Veronica as companion. She's taking more damage than enemies, and i'm constantly cripling myself too. But clearing a room with a single shot is quite cool.

i have the perk and all i have to say is that they should change the colour of the explosion to red when using laser weapons

Tried it out, loaded an earlier save and scrapped it. Went with Laser Commander instead.
