As to what exact percentage the daemon helper gives to discovery boost, I can't really say, sorry (though if I refer to tower events, when a helper daemon greatly increases something, it's around 35% I think, though it is highly likely it's different in GCQ). Concerning your second inquiry, yes, you have to be the last hitter in order for the boost to activate.

Hope this helps :)!
