Author's notes

"Expelling goo!" The 5th build in the "Concerns of The Deep" series, made for beginners and for fun. They are not aimed to be the most meta builds. This one is oriented around Splatter (1). You'll be goopin' all over them and dealing huge damage! Extra Credit goes to VeMi! Join the Viscous Discord: discord.gg/viscord

1Welcome to Deadlock! The Concerns of the Deep are a set of 6 builds, created for Beginners and to enjoy various playstyles.‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ ‎ So you want to play Viscous but don't know where to start? This build will help you learn his most basic playstyle: Splatter! ‎ ‎ ‎ ‎ ‎ ‎ ‎ Splatter bounces twice by default, and 3 times when fully upgraded. Always try to throw it in a way that'll make bounces hit your target for additional damage! ‎ ‎ ‎ ‎ ‎ ‎ ‎ Viscous is one of the few characters to have an Alt-Fire (Right Click). It shoots a projectile with a short range that explodes. You can use it to poke your enemies around cover during laning phase! ‎ ‎ ‎ ‎ ‎ ‎ ‎ NOTE: After recent changes, Splatter might not be as effective anymore. Testing is ongoing. ‎ ‎ ‎ ‎ ‎ ‎ ‎ Join the Viscous Discord: discord.gg/viscord
