For a detailed list of skills and their effects, see List of skills.

Skills are special abilities used by cards in battle. The effects vary depending on the card. Some common skill effects include boosts to front line attacks, decrease in opponent front line defenses, and elemental boosts. Skills affect both the front line and the back line of either player, but only front line cards can activate skills in battle.

Skills are generally restricted only to Rare and Ultra Rare cards, though there are some Common cards which possess skills.

Card skills are often considered to be one of the most important factors in battles, and one of the most important considerations when deciding which cards are present on a front line. As such, cards with good skills, regardless of stats, are often worth more than similar cards with less sought after skills.

The percentages are a bracket. lower end is skill 1, higher end is skill 10.

If no brackets are present, the value is for skill 10

In regards to questions regarding activation frequency with level, the details are fairly complex. The confusion revolves around differences in the skill type.

1. The skill level does NOT affect activation frequency for any of the skills. A level 10 card does not activate more frequently than a level 1.
2. The card in the 1st position will almost always activate in battles against another player. This includes Battle Royale fights. It's useful to select Anat, Allatu or Lilith as the first card during Battle Royales to guarantee BR point boosts.  This is NOT the case with Raid Bosses. Raid Boss cards, such as "increased damage", "blocking" will activate randomly. This exception is what has caused a lot of confusion about the position of the 1st card activation.
3. Cards that boost damage to ramparts will automatically activate in EVERY rampart battle if the card is in the front line. A hit towards the rampart cannot be higher than 100 * the PWR selected. Meaning if attacking at 100%, hit will be maxed at 10,000. Attacking at 40%, hit will be maxed at 4,000
4. Cards with the exact same skill CAN activate within the same player vs player battle and Raid fights. For example, you may have a PM Rhea and RM Rhea in your front line and they may both activate in the same fight. However, boosts to battle royale points do not stack.
5. Raid Boss cards boost the damage from a single strike out of the 5 strikes from a battle. For example, if your average damage for the 5 attacks is: 10000, 8000, 6000, 4000, 2000 - An activated sk10 Rhea (+70% dmg) in round 1 would make the damage: 17000, 8000, 6000, 4000, 2000. 
6. Skill effects depend on skill level. There's always an extra step between 9 and 10. Examples:

The Activation % of the Random Large/Great/Huge Boost to All Attack is as follow:

Only card that has this skill so far is (Mortality) King Against Knight . Percentages above reflect a total of 72 attempts

Skill LevelEdit

Just like a card's regular level, a card's skill also has levels. Similarly, skills may be upgraded through the act of Enhancing a maximum of 9 times for a total level of 10. As skill level increases, so does the chance of that skill activating (I do not have any proof to support that Cariacou (talk) 02:05, February 6, 2013 (UTC)). Skill effectiveness also increases as level increases. As well, even after a card has reached its maximum level, a card's skill level can still be enhanced up to the tenth level.

Only enhancer cards with skills have a realistic chance of enhancing another cards skill level, though on occasion non-skilled Common cards can in fact enhance skill levels. The odds of this happening are quite low however, and such an occurrence is considered extremely rare.

Skill Testing MethodEdit

Always test in backline, it is the best method I found to isolate from any other factors that could come into play.

Attack an opponent that doesn't activate defensive skills. (best way is to friend someone with a low defense, and hope he does not activate attack drops, or ask him to add a default def line with cards having no drop attack effects). 

Recording backline numbers also gets rid of the possible tension boosts.

Testing ExampleEdit

All my cards are skill 10. No skills of the opponent activated.

Numbers here is Umbral's attack when in backline:

No ActivationEdit

when no skills activate, umbral hits 7257 (which is 9072 * 80%).

2 Activations:Edit

Vamp Lord  & Goga activate > umbral hits 10885 (which is 7257 * 1.25 * 1.20)

Vamp Lord  & Oath activate > umbral hits 11339 (which is 7257 * 1.25 * 1.25)

Vamp Lord  & Umbral activate > umbral hits 11157 (which is 7257 * 1.25 * 1.23)

3 Activations:Edit

Vamp Lord & Oath & Umbral activate > umbral hits 13945 (which is 7257 * 1.25 * 1.25 *1.23)

Vamp Lord & Oath & Groa activate > umbral hits 13606(which is 7257 * 1.25 * 1.25 *1.20)

Vamp Lord & Groa & Umbral activate > umbral hits 13388 (which is 7257 * 1.25 * 1.20 *1.23)

Vamp Lord & Groa & Goga activate > umbral hits 13061 (which is 7257 * 1.25 * 1.20 *1.20)

Skill EnhancementEdit

Decimals are always rounded down.

Higher skill formula:

SkillChance = (given percent) * (sacrifice skill level +1)
                    (2)

For multiple cards:

 SkillChance = (given percent) * (total sacrifice skill level + # of cards)
                     (2)

Note: the multiple card formula only works if sacrifices are the same rarity. Examples at bottom.

Data shown in chart:

As you can see above the level of the skill of the Enhancer Card DOES have an impact on the resulting % chance to increase the base card's level.

Formula example:

Enhanced Card: UR EX skill 4 (attempting sk5)

Sacrificial card: Rare EX skill 7

Given percentage for Rare EX on sk5 UR EX: 8%

Formula for skill enhancement:

 SkillChance = (given percent) * (sacrifice skill level +1)
                     (2)

with:

SkillChance = (8%) * (7+1) = 4 * (8) = 32%
              (2)

Multiple card example:

Enhanced Card: Rare EX skill 7 (attempting sk8)

Sacrificial cards: Rare skill 3 (x3), rare skill 5 (x1), rare skill 1 (x4)

Given percentage for Rare on sk7 Rare EX: 7.5%

For multiple sacrifice cards (of same rarity):

 SkillChance = (given percent) * (total sacrifice skill level + # of cards)
                     (2)

with:

SkillChance = (7.5%) * (3+3+3+5+1+1+1+1 + 8) = 3.75 * 26 = 97.5%
               (2)
