Ravager

''"The flesh golem constructed using twisted necromancy..." ''

The Ravager is a Hardmode boss that can be fought anywhere on the Surface. On top of dropping a unique set of weapons and accessories, its purpose is to act as an efficient, though not necessarily easy, means of acquiring Life Alloys, Cores of Calamity, and other materials via Fleshy Geodes.

This boss receives a significant buff after Providence, the Profaned Goddess has been defeated, and it will begin to drop large amounts of Bloodstone as well via Necromantic Geodes.

Spawn
The Ravager can be spawned with the Death Whistle. It can be spawned anywhere on the Surface as long as it has space to fall onto the player.

Phase 1
The Ravager acts in a manner similar to the Golem, in that it is primarily grounded, travels by jumping, and attacks the player with its several limbs as well as various projectiles. In this phase, each of its body parts besides the body itself can be attacked.

Attacks

 * It jumps into the air and slams back down, dealing extreme damage.
 * After the legs have been broken, the high slam damage will cease, though contact damage with the other body parts is still possible. Sparks, which linger on the ground, will begin to fall from its damaged legs.
 * Its claws shoot out at the player at set intervals, reaching a maximum distance from the Ravager before retracting back in. If the claws are hit once shot out, they will automatically retract back in.
 * Once broken, fireballs will occasionally be horizontally fired from the area where the claws were. These projectiles are unaffected by gravity and bounce a maximum of 4 times before dissipating.
 * Its head fires drill-shaped nukes regularly, which will home in on the player and explode after a short amount of time.
 * Once broken, the body fires a burst of 8 lasers in a circular spread at intervals.

Phase 2
Once all of the Ravager's body parts have been reduced to 0 HP, the body becomes vulnerable, and its head detaches and starts flying around the player. The Weak Petrification debuff is applied to all players, essentially forcing them to the ground by reducing their flight time by 50%, disabling most additional jumps, removing all jump height boosts, disabling mounts, and disabling gravity control.

Attacks

 * All previous attacks cease, and the head no longer fires nukes.
 * It jumps into the air, attempting to line up or intercept the player if they are moving before quickly slamming down on them. This attack's frequency increases as its health decreases.
 * The Ravager will only deal contact damage while slamming downwards during this jump.
 * The head hovers below the player, and occasionally moves around them while firing a burst of 4 small red bolts in their direction.

In Expert Mode

 * Upon landing after a jump, the Ravager alternates between summoning:
 * Two large Rock Pillars that fly up into the air and are launched towards the player, breaking upon slamming into the ground or hitting the player. These Rock Pillars spawn on either side of the player and can be destroyed.
 * Two Flame Pillars that fire bouncing blue flame into the air. These Flame Pillars spawn on either side of the player, and will disappear after a few seconds.
 * The Flame Pillars spawn further away from the player in Phase 2.

In Revengeance Mode

 * The Ravager jumps more often.
 * Its drill missiles track the player more accurately and are much faster.
 * The Flame Pillars shoot projectiles faster.

In Death Mode

 * Its projectile speed is roughly doubled.

Aftermath

 * Once defeated, the Witch Doctor will begin selling Death Whistles.

Tips

 * During Phase 1, fly in an arc above it to dodge the boss.
 * Ravager's large health pool can make this boss take a long time to defeat, especially post-Providence.
 * Using an item with a dash ability or having a speed boost will make it easy to dodge the Ravager's missiles, as they are slow and cannot make sharp turns.
 * Every second jump the Ravager makes, the Flame Pillars will spawn by the player. Keep this in mind to prevent running into them, especially while mid-air.
 * By having the minimap out, the player can see when exactly the boss is jumping by looking at its icon on the map.

Trivia

 * Ravager's theme is Open Frenzy, which was composed by the artist DM DOKURO.
 * DM DOKURO has commented that the song has a motif related to one of his older pre-Calamity works.
 * If the Calamity Music add-on mod is disabled, Boss 4 will play instead.
 * Despite the lore stating it has 'the regenerative durability of a living fortress', the Ravager never regenerates health; however, it does drop Bloodstone once Providence is defeated, which is used in the making of many healing-oriented items.
 * The Ravager was formerly referred to in the mod's files as "Scavenger."
 * The reasoning for this was because there was originally going to be an enemy named the Scavenger, who would use the original Ravager sprites.
