Every single-Bangboo page on GameVika follows the same layout: the header shows the rarity stars, the name, a Rank tag (S or A) and a short in-game flavor line. Below that, if the Bangboo has skill data, come three Skill blocks — Active, Additional Ability and Chain Attack — each listing the skill name, cooldown (if any) and effect description. Then come the summary blocks shared across every Bangboo: a Bangboo tier ranking, a table for picking an S-rank Bangboo by team faction, an explanation of leveling and System Optimization materials, how to obtain the Bangboo, and finally a grid of same-rarity Bangboo for quick comparison. Reading in order is enough to decide whether the Bangboo you are looking at is worth investing in.

The table below is a Bangboo tier ranking compiled by GameVika from several community sources (not an official in-game stat), comparing relative strength among Bangboo in the same role. Tier 0 is the strongest group, down to Tier 3. Note: a high tier does not always mean pull it before Agents — a Bangboo only fills one fixed team slot, so matching the exact team you are building matters more than chasing a generic tier. The list only includes Bangboo that already have ranking data; newer units the community has not yet placed will be added later.

Many S-rank Bangboo have an Additional Ability that only activates when your team has enough characters of one Faction or one attribute — picking a Bangboo that matches the team you are running is the surest way to unlock its Additional Ability. The two tables below list the faction/attribute condition for S-rank Bangboo by their two main roles. GameVika compiled this faction info only for the named S-rank Bangboo below; faction data for A-rank Bangboo has no public source yet, so it is not listed here — do not extrapolate these faction conditions to A-rank Bangboo.

Every Bangboo has 3 skill blocks, best read in this order: Active Skill — the main attack; the block lists the skill name, cooldown, and a description of the damage type and Daze it deals; Additional Ability — a passive effect that only turns on once the team meets an attribute/faction condition (e.g. needing 2+ same-attribute or same-faction Agents), listed line by line; Bangboo Chain Attack — a special move triggered through the Chain menu, with its own damage and Daze description.

Leveling these 3 skills is not independent: <small>every System Optimization (ascension) adds a combined 6 levels split between the Active Skill and the Bangboo Chain Attack; every Logic Core update adds a combined 4 levels split across all 3 skills; the Bangboo Chain Attack alone does not consume the team's Chain Attack turn when used — cross-checked against multiple independent sources.</small> Players choose which skill eats each level-up point.

Ascending a Bangboo is called System Optimization, a separate mechanic from Agent ascension. <small>The core material is Ether Electrolyte, with Energy Transfer Fluid and later Concentrated Cooling Fluid required at higher tiers, plus a rising Denny cost per tier — the same structure across every Bangboo, cross-checked against multiple independent sources.</small> A Bangboo reaches max Lv60 through 5 System Optimization tiers; stock up on materials before ascending so you do not have to stop mid-way to grind. Because this material pool is entirely separate, Bangboo ascension does not compete with Agent ascension resources — you can do both in parallel.

A Bangboo's three main roles decide which team it fits: a damage Bangboo suits teams needing extra DMG or Anomaly buildup; an energy-support Bangboo suits teams starving for Ultimate energy; a buff Bangboo suits teams that need one specific stat amplified. For S-rank Bangboo, the surest way to pick is to follow the faction/attribute condition in the "Pick an S-rank Bangboo by team faction" table above: run a team that matches the Bangboo's faction and the Additional Ability turns on. A Bangboo only fills one slot alongside 3 Agents, so pick the one that plugs your team's actual gap rather than the highest-tier one.

Bangboo pull from a dedicated banner called Signal Search — Bangboo Channel, entirely separate from the Agent and W-Engine banners. <small>Each pull costs 1 Boopon, with a full 10-pull costing 10 Boopon; Boopon comes from Hollow Zero, Rally Commissions, the Bangbuck Exchange, and limited-time events — cross-checked against multiple independent sources.</small> Since the Bangboo Channel has no fixed rate-up for any single unit, targeting this exact Bangboo means pulling until it drops (soft pity typically kicks in around pull 75-80, similar to other banners) — there is no way to pick it directly.
