How to Scale the Snail
Chemsnail is the counterpart to the ever popular Monitor Lizard. While this little fella may not be as quick, an emphasis on Slow adds a new angle of attack to Poison builds.
Finding the key items to go with your snail Friend isn’t too challenging, but what must be prioritized is scaling its Poison. Always be on the lookout for Extracts or loot items (which can give Extracts) from vendors, events, and level-up rewards.
Cool LEDs
The next most important piece of the puzzle is also one of the earliest available pickups. Cool LEDs is the fastest and most reliable source of Slow. By setting up your items to the left of your Core, you can trigger this effect multiple times while your opponent is stuck waiting for their items to charge.
A one second Slow isn’t a lot, so make sure to upgrade to at least Silver tier. Alternatively, you can look for Slow scaling items such as Makeshift Barricade at The Curio.
Pylon
Turning Slow into Haste is what truly puts this build into overdrive. Pylon creates a continuous loop where the enemy board is Slowed while yours is Hastened. The synergy between Pylon and Cool LEDs is crazy. Putting these items together is what enables Chemsnail to approach Pufferfish levels of Poison.
Since Pylon is the only source of Haste, it’s important to prioritize its upgrades. Even with a speedy Slow engine, a one second Haste effect wears off quickly. Do your best to ramp it up to at least two seconds ASAP, either via upgrades or Rocket Boots.
The Core
What’s great about this build is that no specific Core is required. The key text that glues it all together is “When you use any item to the left of this, Charge this 1 second”. It's all about having multiple activations to trigger your items as much as possible. All that in mind, the three Cores I would recommend are The Core, Armored Core, or Companion Core.
The Core is the most generic and allows the flexibility of Charging another item. If you happen to pick up something more powerful, you can position it to the far right to accelerate it.
Armored Core is a more defensive alternative that helps keep you alive while your Slow and Poison whittle down their health.
Companion Core doesn't have the same Charge requirement as the others, but is great for building into the Miss Isles variant.
