Gnomes and Gnome Rewards
Kill Gnomes with small loot sack icons and win the battle against the enemy to earn extra rewards.
Gnomes are very rare Troops that can appear randomly in most game modes. Gnomes will have a 50% chance to run away if their Mana is full and their Spell is cast - Kill them before they run away! There are Treasure, Glory, Pet and Jewel Gnomes.

How to find a Gnome
You don't need to unlock Gnomes as they have a very small chance to spawn into battles, including:
Quest
Explore
PvP
Pet Gnomes only appear in PVP (including ranked PVP, casual and Arena)
Challenges
Arena
Gnomes should not spawn in other battles such as Guild Wars and Training Battles. When they appear, they will replace another Troop card in the battle.
What do Gnomes look like?
An NPC Treasure Gnome that drops special rewards will have a loot sack icon in the corner of a card. If the Gnome does not have a loot sack it is a normal Troop card collected on an enemy player's team. Each different type of gnome has a different card.

Types of Gnomes and Gnome rewards

Each Gnome killed has a chance to drop a reward (indicated with the loot sack at the end of a battle) as well as a very, very rare chance to earn a Vault Key (and a smaller chance it will be an Epic Vault Key). The Gnome must be killed, and the battle won to earn the rewards.
From each Gnome, you can earn different rewards. Some share the same rewards, but you can earn higher quantities with them. Each Gnome can give you:
Treasure Gnome
Souls, Gold, Glory, Keys, Diamonds, Vault Keys, Traitstones
Triggers a 1-hour Pet Rescue for your Guild
