Pros & Cons

Pros

• + Good clear
• + 124% increased skill duration for smoke mine and phase run. Smoke mine lasts 13.3 seconds, phase run lasts around 4.18s with no frenzy charges up. The cooldown on phaserun is 4 seconds meaning we have permanent up time with no frenzy charges, With 6 frenzy charges youll get about 15s of uptime, great for delving into darkness.
• + smoke mine + phase rune = 80% increased movement speed at all times.
• + Mirage archer + CA is amazing for indoor maps
• + Has one of the most amazing feelings of 
• + progression for a character I've played so far, and im just into maps.

Cons

• -Kind of squishy until you can get some life on gear.
• -During leveling and mapping you're going to find bosses and some rares tanky, especially hexproof mobs before you get some really high end items.
• -New Caustic Arrow is kinda ugly so you'll want the mtx

Great news is with the CA buff you can start the game with CA now, The skill has pretty decent clear, but single target is going to be lacking earlier in the game before you get major item upgrades.

Other tips

First things first out of the gate if this is a league starter character for you. Find two 1 hand weapons with 3 green sockets for your offhand and equip two of them, Then fill the sockets with spare caustic arrows. Fret not you can level the gems even if you don't currently have the weapons out. This is for a vaaling them for a chance at a level 21 gem, good damage boost later on.

Rares should focus on resists in the earlier acts more than life. Try to find res as high as possible early on and try to find something with equal or better res but with better life as you play.

Look for a 4l green to carry you to maps. CA > pierce > swift affliction > mirage archer/void manipulation
