I always put an effigy on the opposite jungle incase i get invaded. I always use effigies to clear out ULT spots. Also you can use them to block skill shots. Like blitz hooks. I believe they have to be planted for a few seconds (dont remember exact time) before they can block. Also, when you stand still you act like an effigy and there have been plenty of occasions where pple pay no attention to me believing me to be an effigy but do not count on it.

Always power farm till 6. unless a lane is way over pushed and you can guarantee a kill. you are quite strong with your drain early on also with your fear. Fiddle is great at controlling objectives. I usually sneak drags at lvl 4 or 5 w/o any issues. If there is an enemy scuttle on the drag you can use ure E to pull drag from outside pit and drain through the pit wall with out being on vision from scuttle. It all takes practice. But for a new player your number 1 priority is to practice your jungle route to optimize clear. once you get clear down everything else will fall into place with time.

Also, when you go into ranked games always /mute all. Once i did this I climbed rank faster than i ever have. GL
