In Roblox Bloodlines , “every arm” doesn’t give a special permanent stat by itself—what people usually mean is:

  • What bloodlines (clans) give you when you spawn with them
  • What armors / outfits (often called “arm” by mistake in chat) give you in stats
  • Or how arm healing works (since losing an arm is a mechanic)

Below is a clear breakdown of each, based on current community guides and the Bloodlines wiki.

1. What Each Bloodline Gives You

These are the main bloodlines and their key effects (chances and exact numbers can vary slightly with updates, but this reflects the widely cited data).

Rare / High‑Tier Bloodlines

  • Otsutsuki (≈1%)
    • Lets you break 5 chakra points instead of 4
    • Grants Byakugan and access to higher Byakugan stages
    • Access to special abilities like the rift and “Moon Rags” outfit path
  • Uchiha (≈1–2%)
    • Grants Sharingan , which can evolve to MS → EMS → Rinnegan
    • Strong visual/ocular abilities and often fire-style synergy
  • Hyuga (≈2%)
    • Grants Byakugan up to Stage 4
    • Focused on precise strikes and vision-based combat

  • Akimichi (≈16%)
    • Butterfly Mode transformation
    • Access to expansive jutsu (size/strength-based attacks)
  • Haruno (≈16%)
    • Greatly improved healing abilities
    • Often used for support/medic-style play

These are the “what every bloodline gives” details most players care about when rerolling or trading.

2. What Each Armor / Outfit (“Arm”) Gives

People often say “arm” when they mean armor sets or outfits. Each set gives different stat bonuses (defense, chakra, speed, etc.). A widely referenced guide lists these armor sets and how to upgrade them:

Common armor/outfit types include:

  • Rags / Moon Rags / Zetsu Rags – Early to mid-game outfits with basic stats; Moon Rags tied to Otsutsuki path.
  • Reanimated Cloak / Akatsuki Cloak – Mid/late outfits with higher defense and style bonuses.
  • Senju Armor – Focused on durability and often synergy with Senju abilities.
  • Wanderer’s Outfit / Brawler’s Outfit / Fighter’s Outfit – Various combat-focused stat spreads (more defense, taijutsu, etc.).
  • Biyo Armor – Specific set with its own stat profile (often mid-tier).
  • Thunder Cloak – Tied to Ayrui/lightning playstyle; boosts lightning-related performance.
  • Peacemaker – Another late-game outfit with strong overall stats.

Exact numbers (e.g., “+X defense, +Y chakra”) change with patches, so the most reliable way to see current values in-game is:

  1. Open your inventory
  2. Hover over or equip the armor
  3. Check the stat tooltip for defense, chakra, speed, etc.

Videos titled “Armor and Rings” go through each set’s stats and how to upgrade them with materials and NPCs.

3. “Arm” as in Losing/Healing Your Arm

Bloodlines also has a mechanic where you can lose an arm in combat. When that happens:

  • Your character’s combat effectiveness drops
  • You need to heal the arm to restore full functionality

The standard healing method (as shown in recent guides):

  1. Get a Sauna Leaf (rare drop from the Golem)
  2. Find the NPC near the hot springs / bath area (often described as an “ugly man” by the water)
  3. Talk to him and select the option like “I have a sauna leaf”
  4. Jump into the hot water and stand so your missing arm is visible
  5. After a short sequence, your arm is healed/restored

This process is covered step‑by‑step in multiple 2025–2026 guides.

Quick TL;DR

  • Bloodlines = clan you spawn with; each gives unique abilities (e.g., Sharingan, Byakugan, Eight Gates, Wood Style, sealing chains, shark mode, healing buffs, etc.).
  • Armor/outfits (often mistakenly called “arm”) = equipment that gives stat bonuses like defense, chakra, speed; each set has different stats and upgrade paths.
  • Losing an arm = combat mechanic; you heal it using a Sauna Leaf + hot spring NPC + bath sequence.

If you tell me which exact “arm” you meant (bloodline, armor set name, or the arm‑loss mechanic), I can list the precise current stats or steps for that one.
