Slayers 2 bosses and what they drop

Walk up to a world boss and its whole loot table shows under the health bar, with a chance beside every item. Most items sit at 3% or 5%, which is why forty kills without a katana is bad luck rather than a bug.

The Flame Hashira Rengu: the health bar, and under it every drop with its chance.

How many kills is normal?

At 5%, it takes 45 kills before nine players in ten have the item. At 3%, the rate for every haori, it takes 76. Pick a boss and put in your own count.

BossDropKills so farChance you see in game now (optional)

Chance of at least one Serpent Haori in 30 kills, at 3%

60%

So about 40% of players who kill Obari 30 times still have nothing.

50% sure: 23; kills
90% sure: 76; kills
99% sure: 152; kills

3% is the launch-day chance under Obari's health bar. Every kill is a separate roll. Skill scrolls have had a pity at 35 kills since the V0.135 update, so once the line is open to you, you should not need more than 35 kills. The game does not show the pity counter, and the odds here ignore it.

Every boss’s drop list

The 17 full world bosses share the same stats: 3,000 health, a World Events Chest, 1,000 experience and 450 Wen per kill. The skill line on each (the move scroll) is struck through for a player who does not qualify, with the reason beside it: Must be Slayer on a breathing move, or Missing plus the style or art. Names in brackets are their anime counterparts.

These are the launch-day chances. The v.09 update increased all boss skill drop rates by 5%, so every skill line is now higher: seven of the eight Hashira bars now read 10% on the skill line, up from 5%, and so do Domae, Akazo, Nezura and Fujiko. Zentaro’s has not been seen since the patch. Why a scroll line can stay struck through even after you learn the style is on the weapon compatibility page, and a skill that still will not drop is covered by the 35-kill pity. Fujiko is the odd one out, with 3,200 health, an Ice Chest, a 1.8% outfit and a level 150 line on her weapon and outfit. Where she, Zentaro and Akazo stand is on the boss locations page.

What the bars look like

A struck-through line is one you cannot get yet, with the reason in red beside it. Gyutai’s Blood Sickles, Domae’s War Fans and the Stone Trainee’s Axe and Mace were the only 7% items at launch; the V0.98 update then raised the Axe and Mace to 15%.

Gyutai's health bar with the drop list printed under it — `The Blood Sickle Demon` `Gyutai`: the health bar, and under it every drop with its chance.

Domae's health bar with the drop list printed under it — `The Cryokinetic Demon` `Domae`: the health bar, and under it every drop with its chance.

Fujiko's health bar with the drop list printed under it — `The Bladed Wagasa` `Fujiko`: the health bar, and under it every drop with its chance.

Water Trainee Sabito's health bar with the drop list printed under it — `Mini Boss` `Water Trainee Sabito`: the health bar, and under it every drop with its chance.

Saneri's health bar with the drop list printed under it — `The Wind Hashira` `Saneri`: the health bar, and under it every drop with its chance.

The Stone Trainee's health bar with one drop listed under it — `Mini Boss` `Stone Trainee`, `600 / 600`, `Common Chest`, and a single drop: `Axe and Mace x1 (7%)`.

Bosses that only fight at night

Walk up to Sumari, Yahari or Reaper in daylight and the spot where the health bar would be says Come back at night instead. Sumari and Yahari and Reaper have their tables above, read at night. The same night rule covers Muzan and the horned demons that drop Beast Cores.

Sumari's health bar at night with two drops listed under it — At night: `The Temari Demon` `Sumari`, `3000 / 3000`, `World Events Chest`. `Spiraling Shot x1 (5%)` is struck through with `Must be Demon`; `Sumari's Outfit x1 (5%)` is not.

The whole boss route in one run.

Before you farm one boss for its katana

Skill scrolls need the path
To a player who is not a Slayer, Zentaro’s bar shows Flaming Thunder God struck through with Must be Slayer. Learn the style first: the breathing checker shows what each trainer wants.
Each hashira is also a trainer
Zentaro, Rengu, Shinora, Tengai, Obari, Saneri and Gyorei are each both a breathing trainer and a boss. Paying the trainer and beating the boss are separate things. Every Hashira bar except Gyorei’s also carries that style’s katana; what each one becomes at the forge is on the weapons page.
Demon arts drop here too
Akazo, Domae, Gyutai, Enru, Nezura, Datai, Sumari, the Reaper and reportedly Yahari each carry the last move of one demon art. See Blood Demon Arts for which boss belongs to which art.
