Prisoner Armor · Lands of Jail Codex

Gear · Robots

Each formation can use one robot. Players call them Prisoner Armor; the game’s tooltips call them Power Armor. A robot raises one troop type's ATK and DEF, gives you a pilot skill you can turn on, and has a War skill that works in every PvP fight. That War skill is what makes one robot better than another.

Use Phantom Cat for the Cage and rallies, Musashimaru for solo attacks and Bastion for defense. Level up the robots you equip, follow the level targets below for the rest, and turn on all pilot skills together before a big fight. Every robot's pilot skill unlocks at Lv.10.

What a robot gives you

ATK & DEF increase

Raises one troop type's ATK and DEF, only for the formation the robot is on: +39%, +63% or +76% at max.

Pilot skill

A buff you turn on. It unlocks at Lv.10 and lasts for 2 hours, whether or not the robot is equipped. Pilot skills from different robots add up.

Core skill

Has two parts. The Arrest part only works in Arrest and Arena stages. The War part works in solo attacks, rallies and defense, and goes up one level for each core.

One robot per formation.

Phantom Cat

Best for the Cage & rallies

+37.5% Lethality for every troop, and every 4 Shooter attacks fire an extra +80% Tactical DMG (MAX). Rallies and the Cage use mostly Shooters, so its Shooter ATK & DEF boost and Tactical hits help most of your army.

Shooter ATK & DEF +76% (MAX)Pilot Skill (MAX) +10% HP

Musashimaru

Best for solo attacks

Shieldbearers and Shooters get +30% Lethality and take 45% less damage (MAX). Solo armies use only 0–5% Bombers, so this helps almost all your troops.

Shooter ATK & DEF +76% (MAX)Pilot Skill (MAX) Enemy DEF −10%

Bastion

Best for defense

+40% DEF, +35% Lethality and +50% Tactical DMG for every troop, with +230% more Tactical DMG on rounds that aren't a multiple of 3 (MAX). Players use it on defense to raise their Tactical DMG; the robot deals none itself. Defenses with lots of Bombers also get its Bomber ATK & DEF boost on the 35–45% of their troops that are Bombers.

Bomber ATK & DEF +76% (MAX)Pilot Skill (MAX) Enemy ATK −10%

Dauntless

New in Season 7

Every troop takes 45% less damage. If your Bombers outnumber your Shooters, Bombers get +200% basic-attack DMG; otherwise Shooters get +100% (MAX).

Shooter ATK & DEF +76% (MAX)Pilot Skill (MAX) Enemy troops' HP −10%

Robots · Cores

Cores & Core Paths

Cores level up a robot’s War Skill. How the three modules work, which nodes to take, and what every tier costs.

Cores: how the War Skill levels up

Every robot has three core modules, one for each mode. Each module is a tree of upgrade nodes that you pay for with that module's own chips. Every core you reach adds one level to the robot's War Skill. Robots 1–2 max out at 6 cores, Robots 3–6 at 12, and Robots 7–12 at 15.

Solo Module · Solo Chips

Solo attacks.

Barrier Module · Barrier Chips

Defense.

Formation Module · Formation Chips

Rally attacks.

Core paths: which nodes to take

In each tier, upgrade in this order: Troops Lethality → one troop type's Lethality → Troops HP → one troop type's HP → that tier's core. The guide picks the same troop types in every tier, I to V. Solo and Rally use the attack path; Barrier uses the defense path.

Core

How to read a module's level: it adds up node levels plus cores. Each node goes up to 10/10, so one tier is 40 node levels plus 1 core = 41. A module at Lv.82 has 2 cores, and one with all five cores on these paths shows Lv.205.

The five cores: Core Upgrade (I) · Core Amplification (II) · Core Evolution (III) · Core Breakthrough (IV) · Core Overdrive (V).

Node costs, in chips

Tier	Troops node	Type node	Per core
I	710	370	2,160
II	1,460	710	4,340
III	3,870	1,930	11,600
IV	7,250	3,610	21,720
V	10,010	4,990	30,000
I–V			69,820

Troops nodes boost every troop type and cost about twice as much. "Per core" is the cheapest way to reach a core: both Troops nodes plus one troop-type node for each stat. A full Lv.15 War Skill needs 69,820 of each chip type, about 210,000 in total.

ExampleOne core at a time: Phantom Cat

Cores	Lethality	Tactical DMG
1	+2.5%	+4.4%
2	+5.0%	+9.8%
3	+7.5%	+15.2%
6	+15.0%	+31.4%
15	+37.5%	+80.0%

Every robot has its own numbers, but they all grow the same way: one War skill level per core. For Phantom Cat, Lethality goes up 2.5% per core. Tactical DMG starts at 4.4% and adds 5.4% per core, so 6 cores give exactly the 31.4% seen in real battle logs.

Lv.60	29,050	21%
Lv.90	103,550	74%
Lv.100	139,850	100%

Level the robots you equip as far as you can. Their ATK & DEF increase only applies to the formation they're on. The guide below takes Phantom Cat and Musashimaru to Lv.90–100.
Don't max the rest. Every pilot skill is already unlocked at Lv.10, and the guide stops most robots at Lv.10–60.
Put cores into your main robot first, along the core paths above.

Pilot Skills

The buff each robot’s pilot skill gives, how long it lasts, and its cooldown.

Pilot skills at a glance

They work even if the robot isn't equipped, and they add up, so turn them all on together before an important fight. (MAX) marks max-level values; lower levels give less.

Hercules α	Next gather finishes instantly (MAX)	1 use	16h

How the skills grow

Every robot gains the same amount per core-skill level. The three groups only differ in how many levels they get: Lv.6, Lv.12 or Lv.15.

Arrest line	Per level	Lv.6	Lv.12	Lv.15
Base Arrest stat	+4%	24%	48%	60%
Squad DMG	+2%	12%	24%	30%
Squad DMG taken	−1.5%	9%	18%	22.5%

War skills grow one level per core. Each robot card above shows what one core upgrade adds. How often a skill triggers never changes with level: Phantom Cat triggers every 4 Shooter attacks at any level; it just hits harder when maxed.
