Skills

Mechanics
Skills are the backbone to a hero's combat ability. Each Hero has 1 Inherent skill, 1 Overdrive skill, and 2 customizable skill slots that can accommodate any skill from their class type. For example, a Skirmisher can only use skills of the Skirmisher class, and not those of the Mage class. Inherent skills begin at Lv. 1 and can be upgraded in the hero's detail page.

Leveling up Skills
Equippable skills are upgradeable using skill shards of the same type. You will need to collect enough shards to meet the upgrade threshold. Typically, skills earn a 10% increase in damage per level up. Different rarity of skills also level up at different paces.

Collecting
Skill shards can be earned throughout the game from multiple sources. You do not immediately unlock a skill, unless you earn the base amount of shards needed to Learn it. The rarity of a skill determines how hard it is to unlock and upgrade.

As one of the primary customization features for heroes, having a diverse set of skills will help you carry your party further. Find skills in:
 * Loot Drops - Only limited to small amounts of Tier 2 - 4 Shards, this will be a passive way that new players accumulate basic skills. Rare skills do not drop directly from combat.
 * Skill Chests - Earned from Resource Battle (Treasure Hunt). This is the most consistent way to grind shards.
 * Supply Chests - Occasionally you will find a supply chest during a battle. These contain all kinds of goodies, including skill shards.
 * Summoning Shop - All summons from Sophia's shop will have a chance to drop skill shards. This will drop the equivalent amount of shards needed to unlock the skill immediately, so you will start it off at level 1.
 * Missions - Reaching certain milestones will unlock achievements that have a skill reward.
