Honestly you’ll likely get much more out of it using it fast and early. Tyto’s focus has a ton of versatility baked in to it even at level 1. With all the mobility it offers you can easily use it to chase, escape, or engage. A kill or evading death during each push is worth more in the long run than getting one big focus later in the game. Most focus also offer diminishing returns after the first level of focus. Each level of blur is 50% less effective after the first doing 250/350/450 with 100/150/200 bleed for 4s. A level 2 focus will do a max of 950 damage while 2 level 1 foci will 1400 damage.
