The goal of this build is to spam your Q/W and bronze talon.

Be careful about the heroes specified in the threats section, you can kill them easily but they can do so to you too. Don't get greedy. Stay at a good range.

Why those talents

Level 1 :
GO FOR IT Most rewarding quest at this tier, it gives you +200 damages on your W and vision and it's not too hard to acomplish thanks to mobius loop.

SO SO Not as bad as compounding aether, you can pick it if you find yourself struggeling with mana and it boosts your damages by 5% on both your Q and W.
SO SO Can be picked if the enemy team has cloacked heroes or a good ambush comp. Can help you aim from long range in areas where you're not supposed to have vision.
NOPE Worst talent of this tier only gives 100 damages on the Q... Really doesn't do much.

Level 3:
GO FOR IT Really good and versatile talent. It can help you give the extra bit of damages missing to kill a target, it can help you deal with minions and bosses, it can calm down the diving/fast moving enemies since you don't have to aim and they can be hard to hit with your spells.
SO SO Hitting 2 targets CAN be good but it doesn't happen too often and doesn't help you in any other way.
NOPE Doesn't do enough to be considered.

Level 6:
GO FOR IT Core talent of this build, allows us to do the spamming part on the W.
SO SO This talent isn't good for the spamming build. But IS good in the OTK build.
NOPE Meh we're not there to put our enemies in stasis... Rwaaar !! We're there to kill.

Level 9:
GO FOR IT Provide great zoning capabilites for a long periode of time.
NOPE 70 sec to do a bad pyroblast. Just nope. Can be used to repel chaser but don't get chased.

Level 12:
GO FOR IT Best talent of this tier. By increasing your range you increase your capacity to deal damages but also your safty by putting a greater distance between you and you're enemies.
NOPE You might think that this talent is good. But realy it isn't. You backing out of the fight really isn't a good thing it's almost like you were dead.
NOPE A bit better ice block but we don't have to get as close as Jaina for exemple to hit our enemies. The goal with Chromie is to stay far from your enemies.

Level 15:
GO FOR IT Allows you to turn up the volum up to 11. With that you can spam your Q and Bronze Talons.
SO SO I used to use this talent but in practice it's effective to burst but not spam.
NOPE Hardest to use for not enough result don't pick this one.

Level 19:
GO FOR IT Provide great zoning capabilites allows you to lock more entrance point on objective point.
SO SO Improve your zoning capabilites with your R but not as much as with 3 traps.
NOPE At this point you shouldn't have picked this ult but if you did don't pick this talent because it's terrible. It's really hard to get more than 2 enemies in and even harder to kill both.
NOPE Could have been great but dealing unleveled and untalented damages with the Q is bad.
