judging by what the tree beast could do id say Quinn will be able to somehow implant his will into the dalki giving him a small army of dalki to use
True. Similar to Naruto's clone but dalki instead. if I remember correctly, the demon tier to impower the power it marked or sucked their energy into one body. Like what Quinn did fighting Cindy, when everyone transferred their shadow energy to Quinn. As for how many he could control, there should be a limit to how many he should be able to control. Because controlling many would require enormous amount of mental power or some sort of requirement. People may not like this ability now but if u think about it he could control a dalki and fight using it's body without risking his own life. Also getting injected inside the dalkies body will only make him stronger. Using this method, Quinn can use the dalkis body and get other demon tier. As time goes by maybe he could control more.
It's sad to find out that Andrew has been killed but I suppose his sacrifice will not be in vain now that Alex has be able to give the Demon tier Amulet to Quinn. I have a feeling that because the amulet was made from that sentient tree, that it will only respond to the Person who defeated it,which would explain why it didn't do anything for Alex just now. Can't wait to see what that Amulet can do now that it is in Quinn's hands.
As I said or more precisly guess, it shouldn't give a power boost but most probably mind controlling skill . As we all know the beast from which it was obtain is protected by not on its own , and it would be great to use against them .....
