Monster and Summoner cards cost mana to use in a battle. Each battle you play in Splinterlands will have a randomized mana cost, and this will influence how you create your team. We will expand on this later when we get to your first battle.
Different forms of attack
The stats values represent the physical power, speed, toughness and health of the character. The physical power indicates how much damage your Monster will do per turn to an enemy Monster. There are 3 main types of attacks: Melee, Ranged, and Magic. Melee attacks from position 1 on the battlefield. Ranged Monsters attack from the back row of the battlefield (position 2-6). Magic represents the best possible attack as they can attack from any position. Magic attacks ignore enemy Monster armor and directly attack enemy Monster's health. There are rulesets which affect the battle and affect where Monsters can attack from (more on this later).
Speed
The speed stat determines the order the Monsters attack in. Some abilities (speed) make Monsters harder to hit.
Armor and Health
Monsters cannot lose health until it loses its armor. If a monster has 4 health and 2 armor and is hit by an attack of 4 damage, it will destroy the armor of the Monster. The health of the Monster can be seen below the shield. The more health a Monster has, the longer it can stay in the battle.
Card rarity
The rarity of the card is displayed in the middle icon. There are 4 different card rarities in Splinterlands: common (grey), rare (blue), epic (purple) and legendary (gold).
Experience
The experience stat indicates the level of experience of the card. You level up cards by combining duplicates Monster or Summoner cards. As you level up your card, different abilities can be unlocked, more health/damage/armor gained. For example, if I wanted to level Tyrus Paladium, the Life splinter Summoner to level 3, I would need to combine 5 level 1 cards.
Abilities
Most Monsters will have different abilities. The abilities are listed at the bottom of each card. You can hover over the abilities to see the name of each ability on your Monster or Summoners card.
