I was thinking of an amusing if somewhat insidious power for a Joke Character what do people think?

Disney Music Number (-2): You can make a performance roll to sing an epic song, anyone else in the scene has to roll discipline or they too must start singing, singing counts as a supplemental action (-1) and all actions in a Disney Music number are modified by performance.

I could probably knock something together if you want to see my take on the type of djinn that grants wishes. If you're looking for a sponsored magic, I could do that too. I'll edit one into the post once I finish it.

Much abliged.

Element Eater [-2]
Requirement Physical Immunity (Element), Aspect relating to be an element eater.

Each time you are targeted by your chosen your chosen element get a free tag of the "Empowered by your chosen element" or equivalent aspect. 

Basically a power for the fairly common fire and electricity absorbing monsters. .

Well there are several different balance issues this power has first how much should accuracy boosts cost and the in-game answers are 1 refresh for +2 attack with focus items, 1 refresh for +1 attack with stunts and 1 refresh with true aim (give or take). The power isn't the cheapest way to boost accuracy.

The next point of balance is the true cap. For magic this is skill x 3 as you can add a skill and your lore twice with enough refresh. It is possible with a superb skill cap to have +15 accuracy.

For melee the cap is more subjective as a lot of the ways to raise it most gm's will not allow you can have 6 (with a stunt) 7 (if you allow true aim), possibly 8 (if you allow swing for the fences) or 12 (if you allow sacred guardian).

With the power as written you end up with a Cap of 8 for Weapons so in the mid-range of what is possible with weapons and a fraction of what is possible with magic (about half). 

Mythic skill + Speed powers seem a little OP attacking everyone you want in four zones is basically equivalent to attacking every enemy in most combats.

I am not a great gm mainly because I am pretty poor at changing gears and so their is one set piece I have tried to pull off with multiple groups with very little success and I was wondering how other gm's would do it. The scenario is pretty simple you have a demon which is the condensed despair, horror, blood-lust of a battle of the great war fused with a human spirit (ghost). The party being generally good guys want to rescue the trapped soul from its eternity of playing over the same horrors and so enter the demons pocket world. To rescue the spirit they have to get to the center of the demons nightmare world which means going through barbed wire whilst being shot at by machine guns, mortars etc. Now every time I have tried this scenario it has always lacked the horror I was aiming for and so fell flat. 

If you have the refresh for lots of specializations/focus items then lore can do the role of both so for higher refresh its the better focus.
