The Poison card is unlocked from the Jungle Arena（Arena 9）. It is an area damage spell with a fairly wide radius and moderately high damage throughout its full duration. It creates a circular area in which enemy troops and buildings are damaged slowly over time. Enemy troops will also move 15% more slowly within it. It is a deep orange liquid in a thin oblong vial. A Poison card costs 4 Elixir to deploy.

Strategy[]

• Unlike the Fireball, the Poison's total damage is capable of fully defeating a Musketeer, Wizard, or Electro Wizard. The Poison must be placed in such a way that the troop is in its radius for its entire duration while it is walking.
• Poison can be interchanged for Fireball in a deck if it is preferred to cripple anything in a larger radius. The main disadvantage is that the player will not be able to deal high damage to enemies immediately or push them back.
• The Poison's long duration allows it to deny swarm cards from being effectively used inside its radius. This can be useful on offense after sending in a troop that only targets buildings or a troop that can only attack 1 unit at a time, as the spell will often force a less practical counter out of the opponent. However, its damage on spawning units is not instantaneous, so swarms that can survive its first tick will still be able to land a hit or two. This is also does not work nearly as well against Barbarians, as their higher health allows them to still do massive damage before having almost all of their hitpoints stripped away. This is still a positive Elixir trade, and they will easily be dealt with by Crown Towers.
• Poison is one of the more efficient methods at dealing with buildings that spawn troops, as the spell will not only reduce the building's lifetimer but also damage down the oncoming units. This works just as well against Witch and Night Witch, limiting their damage output and leaving them at critical health.
• Poison cannot one-shot Skeletons 2 levels above it, so players should make sure their Poison is sufficiently upgraded. Poison also cannot one-shot Spear Goblins that are 3 levels lower.
• Poison is a hard counter against the Clone. The spell's 8秒 duration allows it to easily take out any cloned troops and possible death spawns from them, while also dealing damage to the originals.
• Poison can be a consistent counter to the Graveyard, sharing a similar duration while covering most of its radius. However, a few Skeletons will still manage to damage the Arena Tower. These properties also make Poison pair well with the Graveyard as it will quickly defeat any low health troops that are trying to defend against the Graveyard.
• Poison pairs well with the Miner, as its ability to deny swarms for a lengthy amount of time can allow the Miner to deal considerable chip damage uninterrupted. However, this combo is fairly ineffective against cheap tanks like the Knight. Despite this, the mere threat of a Poison spell along with the ambiguity of the Miner's placement will often force the defender to commit a single tank to one spot, rather than them using a swarm to cover multiple placements. If they guess incorrectly, the Miner will still deal some chip damage while not leaving the attacker at a large Elixir deficit.
• Poison is better suited for decks where you can expect your opponent to place defending troops close to their tower, and that those units will stay there for extended periods of time, allowing the Poison's full damage to take effect. For example, against slow moving tanks like P.E.K.K.A. or Golem, ranged troops will often stay in place for a prolonged period of time due to the tank's high hitpoints.
• Sometimes, it is a good idea to combine the Poison with other spells, particularly spells that can keep the troops inside it for longer, like Zap, The Log and Tornado. These spells will allow Poison to deal more damage, as the added effects will keep them inside it for longer.

Trivia[]

• Poison is based on the eponymous spell in Clash of Clans, even sharing the same sound effects and sprites. However, unlike its CoC counterpart, Poison does affect buildings, has no damage-scaling effects and does not affect the opposing troops' attack speed.
• Poison’s effect stays with troops for slightly after they leave the spell’s duration, which is best seen when deploying the Poison on top of a Fast flying troop.
• The Poison is red in Clash Royale, but in Clash of Clans, the Poison is orange.
