Loki Jungle build

You start with beads and get blink later unless the enemy team doesn't have a lot of cc, and then you go blink first. If the enemy has a lot of burst and cc you might have to go Beads + Aegis.
You start by having the person you clear the first buff with hit the buff first to let you backstab with your 3, preferably gank as soon as possible with your 1 + 3 at level 2. if not possible, start hyper farming.
BEADS START -Solo lane ganks are very effective. wait for the enemy solo to engage the wave, stealth to him and have your solo blink them. The damage you do with 1 + basic + 3 + a couple basics are enough to kill a level 2 solo laner even if he doesn't take damage from wave or from your solo.
BLINK START - Look to gank mid early if the enemy mid has no level 2 escape and your mid heavily outclears them. Have your solo laner start on blue and buy Hand of the Gods. Clear speed with your 3 and HoG the exp camp, rush mid and blink 1+3 them. See start build for Mid Gank.
Watch out for down beads on any enemy, they are usually a guaranteed kill without beads up early if you ult them and dump your kit with an ally attacking.
You have a lot of power spikes in finishing Crusher, Hydra and then Arondight. Your 1-shot potential renews every time you get a full item. Late game you are a beast with Bumba's Hammer.
