In-Game Description A trick weapon used by the old hunters, and crafted by the workshop heretics, the Powder Kegs. A giant hammer equipped with a miniature furnace. When ignited and fired, it emits a volley of flame that explodes furiously upon impact. Crush the beasts, then burn them - the brute simplicity of the Boom Hammer was favored by hunters with an acute distaste for beasts. Overview The Boom Hammer requires 14 strength and 8 skill to use. Its physical attack scales highest with strength, and receives very solid numbers up until level 50, at which point it begins to drop off. This is most certainly not a weapon for skill-oriented characters, as investments in this stat return poorly overall even at higher levels of upgrade. Modes: The Boom Hammer and Tonitrus are quite similar in a few ways. For example, it is the only right hand weapon in the game that deals fire damage without the use of a Fire Paper or gems. Additionally, all of its attacks are blunt. However, it does not deal elemental damage in its normal mode. Transforming the Boom Hammer will ignite the tip, adding fire damage and explosive effects to some attacks. Keep in mind though, that the weapon will reset to the normal mode after every attack. Availability Normal: Treasure in Hunter's Nightmare, after you head down the tunnel near the "Grand Cathedral" copy area, you head down the hill and into the house. Down stairs next to the wheelchair is where this item will be.

You might consider using Tempering gems, but these will only increase the physical damage of this weapon. Instead, think about slotting Nourishing gems to increase both of this weapon's damage types. If you look at the tables, you may notice that all of the Boom Hammer's attacks deal blunt damage. This is a key feature that can be greatly enhanced by equipping Adept (blunt) effect gems. Again, don't bother with the Tempering gems; you'll receive a larger bonus from more specialized gems. When transformed, the Boom Hammer's attacks will eat through stamina, so you may want to balance this out with Radiant gems. For more information check the Best Blood Gem Setups page. Key Attacks Normal Mode: The Boom Hammer's normal R1 chain is slow, but will stun-lock most enemies with normal impact. This chain swings back and forth horizontally, which is useful against crowds. Another good feature of these attacks is that they won't rebound off walls and obstacles. This is true for the entirety of this weapon's moveset, but is especially important for wide attacks such as these. In most cases, the leaping R2 will cause enemies to instantly stumble with its heavy impact. It also deals more damage for less stamina than the dashing R1. This attack works as a great combo tool for the Boom Hammer's slower swing speeds. Quickstep backward during any combo and follow up with a leaping R2; this will usually break high enemy super armor. The damage multiplier for the charged R2 is almost double the weapon's overall attack. The time it takes to charge is not that bad and it can stagger foes from behind. Since you're most likely to have low investments in skill with this weapon, a second charge attack will deal more damage than a rear visceral attack. This will almost always send enemies falling forward with massive impact, giving ample time for you to retreat and recover stamina. Transformed Mode: Aside from being mostly unnoticeably slower, The Boom Hammer's moveset remains ultimately the same in this mode. Instead, attacks receive enhancements from fire damage. A high damage combo you can use against enemies with low super armor is a back and forth between the L1 and R1 attacks. Doing so basically keeps the Boom Hammer ignited constantly, which will allow you to deal constant fire damage. The most notably improved attack in this mode is the charged R2. This attack gains a medium area of effect explosion, and for the amount of damage this generates, the charge time is still very good. Don't forget, this can also be used to hit enemies from behind cover! A similar attack is the leaping R2, though the explosion has a smaller radius. Durability Durability of the weapon depletes when used. This means hitting an enemy, destructible object or bouncing off the walls. Hitting undestructible objects and environment does not deplete your durability. Style of an attack or upgrade of the weapon, even different weapon, does not matter - each count as one hit. Every 10th hit against the enemy/object depletes 1 durability. Exception is Tonitrus, which when in self buffed mode, depletes durability at rate of 2 hits. Hitting an enemy in dying animation still counts as hit. Also hitting multiple enemies/destructible objects at once counts as one hit per enemy - hitting 3 enemies at once counts as 3 hits towards durability counter. Shields lose 1 durability every 10th hit. Bounce means when your hit is bounced back off the wall or other objects. Every 5th bounce depletes 1 durability. Not every weapon can be bounced off, Boom Hammer belongs into the category which cannot. Damage reduction when heavily worn. When weapon is at 30% of total durability, it reaches the Risk state and AR is reduced by 30% and when it hits 0% of total durability, weapon is Broken, then AR is reduced by 50%. Boom Hammer which has 100 points of durability reaches risk state at 30 Dur. Workshop's Repair: cost of repair depends on the weapon and its upgrade. For Boom Hammer +0 it's 5 Blood Echoes per 1 point and for Boom Hammer +10 it's 20 (values are rounded), full repair costs for +10 are 2000 Blood Echoes. Notes This Weapon is part of The Old Hunters DLC Uncanny and Lost versions are sold in every Chalice Bath Messengers, both for the same price Uncanny and Lost versions available for purchase after obtaining normal version of the weapon Video: Bloodborne - New DLC Weapon "Boom Hammer" Location by tassssssssss

Note: Damage Multiplier data from official guide checked with http://darksouls2verificationdata.web.fc2.com/motion-bloodborne.html for correction after patch 1.09.

Attack: Attacks are named for the input command required to execute them.

Attack Damage Multipliers: Each attack has a different multiplier. Your attack's power is equal to the attack power of your weapon times this multiplier. Higher multipliers mean stronger attacks.

Type: Damage type determines which gems will boost your attack and which defense the enemy will use to reduce the damage. If multiple types are listed, the attack has two separate damage components that are calculated separately.

Stamina: Each attack costs a different amount of stamina. Numbers in parentheses indicate the cost of the additional action required to execute the attack. For example, a backstep attack requires a backstep, which costs 10 stamina.

Impact: When you hit an enemy, it will be stunned momentarily. Impact is an assessment of how heavy the stun will be. The scale is Light > Normal > Heavy > Massive. Attacks with Massive Impact often cause knockdowns.
