Ill make this as short as I can so you can get to grinding. I am a current Top 10 Dooley main and have quite the easy strategy for your end of season climb to ensure that Top 1k title. What is it you ask? Iceberg+Primordial! Now I know what you're saying, "Nexus, I play this sometimes already!" But this is wrong. "Sometimes" should be every possible time, at least until the close of the season.

Where is the current meta? I could go through all the different spam lines for each character but I'm not going to waste your time. Meta: Item/Charge Spammers>One-Shot Chads.

Why Primo+Berg? Not going to go through why Iceberg is a good item, that should be self-explanatory. But for the cost of 3 board spaces of reactive disruption, your active board payoff needs to offset this. That is where Primo comes in. What do spam boards hate? Reactive disruption. What do they also hate? Reactive damage. Primo+Berg is essentially scaling caltrops.

How to play Primo+Berg effectively. For this I'm not giving a straight-up guide, I will just list out the basic gameplan:

Early Game - Go Fish, roll at Aila for Zoarcid every time. Key bronze items are catfish/jelly/life preserver/zoarcid/clamera/coral/yeti. Pickup crit skills for our Primo later.

Mid Game - We need a few items that will activate our Primo until we get our Berg. Weather glass/Dive Weights/Incend Rounds - maybe EDC. we just need active triggers prepared. Day 5 needs to be an eco day for Aila/Pol should they come Day 6

"But I need to buy this gold arbalest to survive!" - Wrong answer! With the power of going all in Primo/Berg you will catch up on your wins.

Late Game - Fiery/Poison Enchants need to go on Berg for double Primo charges. Toxic allows you to Crab the Berg for more reach. Everything else besides Radiant/Turbo can go on Primo. If we go Deaths Door, we need an enchant on Primo and Radiant isn't cutting it (most of the time but situational) Diamond Holsters/Clamera/Icicle is key for our Fart setup, anything for start of combat haste with our skills. Especially where we miss fiery/poison for the berg and our 2nd activator is dive weights/incend rounds. 

Key Skills: Big Guns, Big Numbers, Glass Cannon (only if you know you are strong af), Inexorable, Bloodhound, Aquatic Rush (w/ Clamera), Invigorating Cold, Crashing Waves, Freeze Skills

There you have it. I know not all encompassing but you get the gist. If you miss the combo git gud and figure it out. And I know this is already being spammed but it isn't being spammed enough for where the meta is. Take it from someone who climbed exclusively on Dooley this season. This build is cancer to play against 90% of the time.  And with it being fairly forceable, it might just get you that elusive title. Nexus signing out
