The "fused weapon" text is probably poor wording, but I do feel we need to note how it is wielding a morningstar, as it can't do so in its natural form. How about "morningstar +1 melee (1d8 plus paralysis)[wielded as human skeleton]"?
So something like this?
Attack: Slam +2 melee (1d4 plus paralysis) or claw +2 melee (1d4 plus paralysis)[using human skeleton] or morningstar +1 melee (1d8 plus paralysis)[using human skeleton] or morningstar -3 melee (1d8 plus paralysis)['pile of weapons' form]
That's a bit messy, but appears to cover all the options.
