The Chosen Ones

Name: Dark Rider / Shadow Swordsman
Attack Damage: 90 - 120.
Attack Speed: Very (Very Very Very Very) Fast.
Hit Point: 30000
Movement Speed: Very Fast.
Mana: 10000.
Attack Range: Melee.

Active Abilities:

Confusion: Upon using this skills, the Dark Rider will summon copies of him on the arena, which they are only shadows, deal no damage and killed in one hit, while the real one is hiding amongst all of the fake one. When the shadows are killed, play the mirror image effect if possible and make it black like the color of a shadow instead of the original green.

Passive Abilities:

Evasion: Because of the Dark Rider / Shadow Swordsman is a shadow and doesn't have a fixed shape, this gives the Dark Rider / Shadow Swordsman a 40% chance to evade enemy's attack. If it is possible, instead of just playing the plain and old boring sign where the "miss" word come out when the opponent miss, make the Orb of Darkness missile death appear on the user's body.

Shadow Strike: When the Dark Rider / Shadow Swordsman is below 60% of his maximum hit point, this skill will be activated, and after this is activated, every time the user land an attack, it will be teleported to a random direction around the opponent and land an attack again, after landing the attack, he will be teleported again and such. This will cause the fighter to be unable to or at least, hard to aim the user to aim their spell on. Hero who have an Area of Effect stun that expand on an AoE around the hero like Phodom's stun skill would make this enemy's skill useless though, because even though he teleported, he only appear on the other side of the enemy but is still in range of his attack, which is melee.

Shadow Form: When the Dark Rider / Shadow Swordsman is below 5% of his maximum health, he will enter his Shadow Form, which grants him an 80% evasion (play the same effect when the attacked miss) and shadow walk (appearing and disappearing all the time).

Note: I tried to make this opponent as unique as possible by making it focuses more on confusion, misses and speed rather than on damage and spells, because after playing The Chosen One for a long time and fought many bosses, I don't seem to cross on a boss that focuses on speed and confusion. Even though with his low damage, his very high attack speed alone is enough to cover his low attack damage.
