Boom Hammer is a Trick Weapon in Bloodborne. It was added with The Old Hunters expansion. There are 3 versions of this weapon: Normal, Uncanny and Lost. The only known differences being the Gem Imprints and the locations in which they are found.
Boom Hammer 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."
Boom Hammer Information
- Transforming the weapon makes the hunter ignite the hammer, giving bonus fire damage to the next attack.
- Requires 16 Blood Stone Shards, 16 Twin Blood Stone Shards, 16 Blood Stone Chunks, 1 Blood Rock and ?? Blood Echoes to fully upgrade
- To perform a Leap Attack, tap forward on the Left Stick as you press R2
- To perform a Transformation Attack, press L1 while performing another attack.
Location
Normal
- The Hunter's Nightmare. Inside a house that looks out of Central Yharnam, the same that is the shortcut to the cleric beast in the main game, where the 10 quicksilver bullets used to be. Be sure to shoot the explosives around the item (or act fast), as the wheelchair huntsman's corpse conceals a delayed molotov set to trigger when you try to grab the Boom Hammer, potential killing you in a huge blast.
Uncanny Boom Hammer
- If you have the normal version: Create Glyph 8i29rqz3 (Pthumeru Labyrinth) and buy from Bath Messengers up a ladder from the main room for 28,000 Blood Echoes.
- Can also be found in the lower hintertomb chalice. Sold by messengers in the 3rd layer of the dungeon.
Lost Boom Hammer
- If you have the normal version: Create Glyph 8i29rqz3 (Pthumeru Labyrinth) and buy from Bath Messengers up a ladder from the main room for 28,000 Blood Echoes.
Player Notes
- Attacking with an ignited hammer consumes roughly double the stamina as non-ignited attacks.
- Ignited hammer also lowers the amount of health recovered on rally attack.
- When ignited, any slam attack (charged R2 and jumping attack) will create an explosion, increasing your AoE.
- The transformation attack has a thrust animation but still deals blunt damage.
- With 50 arcane and weapon at plus 10, it gets +29 phys attack and +64 fire.

Would it be better to put Fire runes into this thing to give it 100% fire output instead of splitting it? Or is it better with nourishing?

This thing is MASSIVELY underrated in my opinion. A lot of people wrote it off a bit because it's such a simple weapon, much like the Tonitrus. While its moveset is simple though, it's extremely effective as it's essentially a miniaturized Kirkhammer for one handed combat, and being able to ignite the hammer for either R1's crowd control of R2's big boom for annoying enemies like Lanterns gives you a small but effective degree of versatility to a simple moveset.
Plus it just looks really cool.

Step 1: Beat Amelia
Step 2: Speed run to the weapon
Step 3: Charge R2 the entire game

This thing absolutely wrecks groups of mobs. Its awesome in the dungeons with all the tight hallways. Its amazing against all Kins and most Beasts. It just melts Amygdala and Ebrietas with that running R2 to the head. You do not get the DPS of a fire or lightning saw spear, but , with the Adept gems you can easily get from the Winter Lantern, your on for a total blast. Good damage when not lit, explosive damage when lit. Managing timing and distance makes for a really rewarding experience when you grouped the enemy together and one shot five of them in one big boom. And, if you land that charged R2 in PVP, its one of the most satisfying feeling a weapon in BB can offer IMO. Its easy to parry and kind of slow, but when it lands, you know where your blood chunk went, that's for sure.

You don't want to hear about Skill weapons. You want to hear about Rifle Spears, Stake Drivers and Boom Hammers. I'm Torgue and I have one question and one question only... EXPLOSIONS?

For a high-damage continuous combo, prime your weapon and do R1, L1, R1, L1, etc. This will cause you to alternate between primed R1 attacks and re-priming transform attacks, causing you to do repeated flaming R1s. There is a delay between attacks but most enemies will be too staggered to retaliate mid-combo, allowing you to combo until you run out of stamina. Just don't try it against enemies who can resist being staggered by it.

Similar to the Pulverizer in Killing Floor 2, you empower each hammer attack with a shotgun shell. BOOM!

Awesome weapon for enemy hunter NPCs. Leaping attacks or charged R2s send them flying, plus fire attacks good for beasts. Underrated weapon

This is really handy on enemy hunter NPCs. It's charged R2s are fast and when they connect it sends hunters flying. Plus you have another chance to hit with a second charged R2 afterwards since the charge time is low. Underrated weapon.

no messengers, but patches24 Jul 2016 19:27
So I went to dungeon 8i29rqz3, and instead of there being the bath messengers, patches was there instead. It would seem that once you befriend patches he replaces the bath messengers in dungeons, and his items don't cost anymore than buying it from the dungeon messengers.
