It is not easy to master the combat system in Legends of Pixelia, but this page will help by giving some info about the mechanics behind it. :-)
An essential way to win a fight in Legends of Pixelia is doing combos. The easiest way to start learning combos is doing the basic combo: (A), (A), (A) (or press and hold (A) for a short time).
Flinching is the short "ouch, I have been hit!" animation that immediately starts when a player or an enemy has been hit by a normal attack. The default flinch duration is about half a second, whereas some skills have a longer flinch time (e.g. Paladin's Force Nova) or no flinching at all (e.g. Vamp Hunter's Orbit Shield).
Some attacks have the ability to throw an enemy up in the air (e.g. Paladin's Spirit). Whenever you are able to hit an enemy again while it is in the air, we're talking about an air combo. One word of caution here: You can't hit enemies that are too high in the air, so time your air combos well. Some skills that throw enemies very high are e.g. Knight's Sky Slash or Barbarian's Shockwave.
When a character that has been thrown into the air lands, it is grounded for a short time. Most attacks don't harm grounded targets, but there are some exceptions (e.g. Barbarian's Shockwave). Whenever you are able to continue damaging a target by picking it up with a ground hitting skill, we're talking about a ground combo.
Some enemies use ground hitting skills, too. Luckily, there are two ways to get up faster:
Endurance, ingame often abbreviated as "Endu", is a state where a character can't be flinched or be thrown into the air, but still receives damage dealt. Endurance is visualized by a yellow glowing orb at the charater's location. Bosses have a skill that grants endurance for a long time, but players have some skills that grant endurance, too (e.g. Block or Barbarian's Whirlwind (Y)).
