I think the first riddle is saying that there is one item that don't give much help (points, bad effect) and that is related to another items that give a better effect or more points...
But I don't understand the second very well... It says that we can call it slow, then we must think of



, but immediately after it says "But not a joke", and we think "Then it isn't any of that items"...
It can be

but it don't fit the rest of the riddle.
But there is a thing that I missed. In the second line of the second riddle it says "But not a joke" and not "But I'm not a joke", so it seems to say something...
