Enemy Types

There are countless enemies throughout the several worlds of Unbound Arc Online, but there are only so many categories they can fall into.

## Monsters

Though most enemies are monsters, only the lowest ranking ones are considered nothing more than that. These make up the vast majority of enemies throughout the UAO game, and provided the enemy isn't more than 3 levels below the monster they are fighting, there really is no chance of the player being killed by a single monster. That said, monsters tend to group up with others of the same kind, and in some cases the sheer numbers can be a problem. Still, aptly leveled players who aren't early level Brain Eaters, still shouldn't find it a problem to solo the entire horde of monsters in the vast majority of cases.

They exist in nearly every non-settled location, and respawn within a few minutes of dying.

## Mini-Bosses

This kind of enemy is a lot less frequent than Monsters, but the 2nd most frequent out of all enemy types. There are between 1 and 5 different Mini-Bosses per Floor, generally split between multiple areas. Their appearance is generally like that of monsters but bigger and slightly more elaborated. Though a single lonesome player (who isn't an early level Brain Eater) can still finish off a Mini-Boss of equal level without that much risk and danger, players who are under-leveled even by just a couple of levels might find themselves among the list of casualties, unless they play it very smartly. Players who group up, even at low levels, should find it easy to beat Mini-Bosses.

Once a Mini-Boss dies, it will only respawn in the next timeblock.

## Mid-Bosses

Mid-Bosses are essentially the same as Mini-Bosses, except much stronger (and generally much bigger too) in comparison. There's generally only 1 Mid-Boss per Floor, but some Floors actually have 2 of them. A single player even of equal level will find it very difficult to beat a Mid-Boss, they might genuinely die fighting one. Still, players who are 3 or more levels ahead of a Mid-Boss, especially if they play it smartly (and also aren't early level Brain Eaters) should find that even if the battle isn't easy, it is one they will win. Parties tend to shine brightest against Mid-Bosses, it's the best situation to form/join one.

Mid-Bosses only spawn once a day, so once a Mid-Boss is dead, you'll have to wait for tomorrow to come before you can kill them again.

## Floor Bosses

One of the most powerful kind of enemies, and one out of only two types of Raid battles. Floor Bosses' mere existence casts a Floor-wide barrier that prevents players from ascending to the next Floor (though they can still go to previous Floors). Once a Floor Boss dies, the next Floor becomes accessible. Because of this, there are exactly 100 Floor Bosses, one Floor Boss per Floor. They also tend to be several feet tall, but their size can vary greatly.

These are Raid type enemies, meaning that it doesn't matter if a player is partied or not, anyone who attacks it will reap the rewards... If they survive. As a Raid type enemy, it takes more than a single powerful party to take it out, several parties have to gather together to fight this monstrosity, with some exceptions in which two or three strong and well organized parties are enough. Even no parties, what matters is the amount of players.

Anyone who participates and survives a Floor Boss battle will receive an extra Progress Point, regardless of level ups. Once a Floor Boss dies, it will never respawn. Floor Bosses will never leave their own battle area, but once a Floor Boss battle starts, the exists become blocked so players can't leave either (unless aided by a skilled enough Jumper).

One surviving player from the Floor Boss fight will be randomly selected to win one piece of Legendary Loot (the highest possible quality)... Careful though, Floor Boss battles are where most players end up dying.

## World Bosses

Similar to Floor Bosses but in even lesser number, World Bosses are the only other kind of Raid battle enemies. World Bosses have colossal sizes, comparable to blimps, spaceships and skyscrapers. They possess much less offensive power than a Floor Boss, but in exchange for that they are far more durable, carrying obscene amounts of HP.

World Bosses don't have specified areas to be in, they appear as they please and have only one goal in mind for their existence: To destroy a settled area(also known as Safe-Zone). World Bosses will move over to a town/city/village/settlement and begin to attack it, killing innocent civilian NPCs and battle ready players alike (if they are in that area). That said, World Bosses will not directly target players as they exist to destroy the Safe-Zones.

If a Safe-Zone is destroyed, the shops and businesses there will no longer exist, meaning players will have less resources at their hands (such as shops to buy gear from, inns to sleep in, houses to buy, even losing owned houses if present in the area).

World Bosses will ignore players as they indiscriminately attack the Safe-Zone in attempts to destroy it, so players should pool their attacks together from behind/below the World Boss to finish it as quickly as possible. If a World Boss destroys a Safe-Zone, it will either run away and disappear, or head to another Safe-Zone in the same Floor to continue the destructive rampage.

Players who help killing a World Boss before it destroys a Safe-Zone tend to get a lot of gear and in some cases, even get awarded store discounts from the locals of that Safe-Zone, who from that moment forth will hail the players as heroes and saviors of that city/settlement/etc. Though there is no obligation for a player to join a World Boss fight, it would be smarter to help, since there will be rewards for winning, and loss of valuable world resources from losing.

The exact amount of World Bosses is unknown, but it is less than Floor Bosses. Once a World Boss dies, it will never respawn.

## Quest Bosses

Bosses who exist solely as part of a Quest. The power and difficulty of this kind of enemy vastly depends on the quest difficulty itself, some might be only slightly stronger than a regular monster, while others might be comparable to Floor Bosses in power (but without the massive amount of players to help in the fight). Their rewards are tied directly with the Quest rewards.

Unless the quest is repeatable, they do not respawn once killed. Even if the quest is repeatable, they only respawn once the quest is accepted again.

## Villains

The final type of enemy... Every other type are monsters, but what if the enemy was Human in appearance and intelligence? Knowing when to fight and when to run, how to play others against each other, how to make full use of their overwhelming power? That is what a Villain is. No one knows if Villains are truly NPCs, because some speculate these are actual Human players who were somehow promoted... While others believe them to be employees of the gaming company who developed UAO. Even if they really are NPCs, Villains are smart and realistic enough that they must be operated by advanced AI.

The number of Villains is even less than that of World Bosses, but the exact amount is also not known, nor where they came from or where they've been the whole time.

In terms of power, a Villain has less stats than a World/Floor Boss, but while the others are designed for raid battles, Villains avoid raids at all costs, instead preferring to fight players in 1vs1 or them vs a single full party of players at most... And with high enough stats, powers and intelligence to make this the most dangerous kind of battle for the player, so even if fewer players die here compared to Floor Boss battles, the chance of dying is greater.

Villains never respawn once killed. Those who kill a Villain will receive many rewards, including one piece of Legendary Gear for each player (in case of party fight)... But if a Villain might actually be a person, wouldn't killing one make you a murderer?
