“ Covers the area in a deadly toxin, damaging enemy troops and buildings over time. Yet somehow leaves the grass green and healthy. Go figure!”
Poison is unlocked from Arena 5 (Spell Valley). The Poison is an area of effect spell that does damage over 8 seconds.
Strategies for using Poison
Poison is the best spell for providing area denial in the game. It not only damages units but can also prevent your opponent from playing them. This trait separates Poison from other spells in the game. When using Poison, you want to do everything you can to ensure that you keep enemy troops in the radius for as long as possible. Musketeers, Electro Wizard, and regular Wizards will all die if you can keep units in the radius for the whole time. It is also important to make decisions on the positioning of the Poison. Sometimes, it is a tough choice whether or not you want to hit more units or get tower damage. Most of the time, aim to hit as many units as possible.
Best Decks for Poison
Poison goes well with and against Poison. On defense, it can kill Skeletons in one tick, but on offense, it can take care of defending swarms. Some Graveyard decks have cards that try to bait it out.
The Poison has an obvious replacement in Fireball, but they do have very different roles in decks. The Earthquake has a similar denial potential but is primarily for taking out buildings.
