DoomKnight

DoomKnight is a special class, available only to accounts who owned a Dragon Amulet for over two years. It is either acquired by buying each piece of the DoomKnight set separately, or all at once for a discounted price.

There are two versions of DoomKnight:

* The current version (V2), which is the only version available to new players.
* The original version (V1), which is only available to existing DoomKnight owners before the class was revamped.

* DoomKnight
* DoomKnight Variant One

**DoomKnight**, or V2, is the revamped and nonrare version of the DoomKnight. This is the only version newer players will have access to.

Every DoomKnight skill has scaling damage, given by the following formula:

* 100% scaled damage = (100 + 2 \* [Player Level])% base damage.
* At level 90, 100% scaled damage = 280% base damage.

Every DoomKnight skill has Scaling Mana Costs (SMC), given by the following formula:

* SMC = (2 + 0.2 \* [Player Level])
* At level 90, SMC = 20.

## Rotation

You can do something like this to get the fight started, assuming Corruption lasts 5 turns:

1. Corruption
2. Shape Darkness
3. (Malefic Binding)
4. Lingering Doom
5. Shape Darkness

As Dark Favor -> Inner Darkness alone deals ~6k damage at level 90, DoomKnight can easily burst down most solo fights within the first 4-6 turns:

1. Dark Ritual
2. Corruption
3. Dark Favor
4. Inner Darkness

Lingering Doom can be inserted both right before and after Dark Favor for another ~4k damage.

## Strategy

DoomKnight is a purely offensive class centering around the use of Corruption.

* If using it would result in a resist debuff (which is becoming increasingly common with more bosses categorized as "Other"), an Evil weapon (i.e. Exalted Apotheosis) is preferred due to Lingering Doom's massive 2-turn DoT. For this reason, DEX/END is also preferred, though depending on the fight, any main stat can work.
* With multiple enemies, a more cautious playstyle throughout is preferred due to Dark Favor's 3-turn time limit. It should only be used when victory is guaranteed or the enemy can purge it from you before it kills you.
* Because Void Barrier's HP recovery **can** be affected by Health resistance, it's highly recommended to have a -All/-Health resistance build while using it, as the damage mitigation becomes much better (as long as the incoming damage isn't too high off a single hit), and can heal you outright when Drain Essence is active. The damage reflection can also heavily damage bosses this way, sometimes bypassing entire phases. Weakening Blow and Malefic Binding are decent alternatives when it is on cooldown.
* Pet Dragon with Protection is practically mandatory for DoomKnight due to the lack of a shield. Assistance is recommended for the BTH and Boost buffs.

**DoomKnight Variant One**, or V1, is the blatantly overpowered original version of DoomKnight. It is only available to players that owned DoomKnight before the class was revamped. It is banned from **all** Inn Challenges except for the following fights (and associated solo fights, if any):

* Elemental Chaos
* Triple Trouble
* Dragonoid
* Jack Crescent and the Gnarly Guitar of Doom
* Cauldron Groupies
* The Timetorn Matrix
* Undead Duo
* Big and Small

Every DoomKnight Variant One skill has scaling damage, given by the following formula:

* 100% scaled damage = (4.2858 \* [Player Level] + 35.713)% base damage, min 100.
* At level 90, 100% scaled damage = 421.435% base damage.

Every DoomKnight Variant one skill has Scaling Mana Costs (SMC), given by the following formula:

* SMC = (2.5065 + 0.3008 \* [Player Level])
* At level 90, SMC = 29.5785.

## Strategy

V1 is a broken class in every sense of the word. Anything and everything dies in 8 turns because of Life Carve, assuming V1's ridiculous damage doesn't kill them first. The only way to balance the class is to remove its ability to play entirely, which is why after Big and Small was released, it's been completely banned from the Inn.
