Re: Absorbtion Burst
At most, a -1/4. It only matters if the burst attack doesn't KO everyone around you. But it should probably do that. I would also take a side effect about destroying the scenery or something to simulate how much power you're throwing off.
Also, if your absorbstion pool is empty or close to empty, it's not really a limitation at all. Unless you need X amount of END in there to throw the thing.
You may wish to make the burst power into a multipower, so you have some flexibility when you lay the smack down. Bricks with strength-like attacks in a multipower are more fun IMO than a normal brick who can either punch or wrestle, blah blah, move thru, blah blah blah.
