How do raids work in Be The Final Boss?

A raid panel appears over your castle with a short join window and a player counter (the video shows Players 0/6, so up to six players). After joining, you load into a boss room — Imperial Knight in the video — where the boss has a phased health bar on a countdown and your goal is to deal as much damage as possible before time runs out.

What do raids reward?

Damage milestones. In the 2026 video, the CURRENT REWARDS track pays Coin (+1,000,000), Soul (+8,000), and Legendary Fusion Shards (+1) at the 3.0M damage tier of Phase 1, and the Phase 2 tier at 10.0M pays Soul +10,000 and Legendary Fusion Shards +2. The HUD also shows a "Next raid" countdown for the following attempt.

What does the castle system actually do?

The CASTLE menu has four slots — Entrance, Walls, Towers, and Throne — and each takes a castle tier that adds combat bonuses, like +5% to +10% Minion Damage across the tiers shown in the video. Equipping one castle family across slots adds a set bonus (Castle Of Gold's set includes Shard +8%, Minion HP +10%, Minion DMG +12%, Boss DMG +6%, and +7% Soul from battles via Castle Prestige). These values are from a 2026 video and may have changed.

What is the best raid team?

The video's answer is max-level Demonic Skeleton Archers for damage with a tank — Skull King, Cursed Bone Guard, or Orc — in front of them. That matches the general community consensus for wave defense, but raid balance changes with updates, so treat it as a strong starting point rather than a permanent answer.

Be The Final Boss Castle System & Raids Guide: Castle Upgrades and Raid Rewards

A walkthrough of the castle system and raid mode in Be The Final Boss: what castle upgrades do, how to join a raid, how damage milestones pay out, and what changes in Phase 2.

Quick answer

The castle system turns your castle into gear: the CASTLE menu has Entrance, Walls, Towers, and Throne slots, and every tier above the Default Castle adds bonuses like Minion Damage, with a set bonus on top. Raids are timed boss challenges announced in your castle — up to six players join, get placed in a boss room, and earn milestone rewards (Coin, Soul, Legendary Fusion Shards) by dealing damage. In the videos, Demonic Skeleton Archers do the damage while a tank like Skull King holds the front. Phase 2 raises the damage goal sharply but improves the payouts.

Video sources

Raid screenshots and steps are based on blankcup's Imperial Knight raid video (2026); the castle menu screenshot is credited to Liam Difu Reynoso's Castle of Gold video. The castle-system feature list was cross-checked against Berlian kecil's August 1, 2026 update video (its creator labels that era Update 3). Menus, bonuses, and reward numbers are exactly as shown in those videos — later updates may have changed them, so verify in your current game version.

Castle system and raids, step by step

1
Upgrade your castle slots before anything else
Open the CASTLE menu and you get four upgrade slots: Entrance, Walls, Towers, and Throne. Each slot takes a castle tier — in the video the lineup runs from Default Castle (no bonus) through Crimson Castle at +5% Minion Damage, Amethyst at +6%, Chronos Bastion at +9%, up to the Mythic Castle Of Gold at +10% Minion Damage on the Towers slot. A full Castle Of Gold set adds Shard +8%, Minion HP +10%, Minion DMG +12%, Boss DMG +6%, and the Castle Prestige set bonus of +7% Soul from battles — priced at 3.0B coins in the video. Treat these numbers as video-era values.
Castle tiers are upgrades, not just skins: each slot adds combat bonuses and the Castle Of Gold set costs 3.0B coins (screenshot: Liam Difu Reynoso, Castle of Gold video).
2
Catch the raid announcement and hit JOIN
When a raid is close, a panel appears over your castle — the video shows Imperial Knight with the text "Join the raid and deal as much damage as possible!", a "Starts in 15s" join window, and a Players 0/6 counter, so raids support up to six players. The HUD corner keeps a "Next raid" countdown so you know when the next window opens. If you miss the join window you wait for the next one, which the video shows arriving on a short cycle.

Load in, then set tank front and damage behind
Joining teleports you into a boss room where the boss — Imperial Knight [P1] in the video — gets a health bar with its own countdown, alongside a "DEAL DAMAGE TO EARN REWARDS" objective and a Leave button. The video's setup is the community's standard: Demonic Skeleton Archers leveled as high as possible doing damage, with a tank such as Skull King, a Cursed Bone Guard, or an Orc holding the front line. The creator claims his Skull King took almost no damage until Phase 2 — that is his result, not a guarantee.
Inside the raid room the boss health bar runs on its own countdown — bring a tank in front and max-level ranged damage behind it.

Push the damage milestones for Coin, Soul, and Shards
Raid rewards are milestone-based: the CURRENT REWARDS panel fills as your damage climbs — in the video it reads 2.3M / 3.0M and lists Coin +1,000,000, Soul +8,000, and a Legendary Fusion Shard +1. The boss telegraphs heavy area attacks like Imperial Judgment with red circles on the floor, so keep your backline out of them. If other players are in the raid, a damage leaderboard tracks who earns the most.
Reward milestones unlock as your raid damage climbs, and the boss telegraphs area attacks like Imperial Judgment with red circles.
5
Expect Phase 2 to raise the stakes
When Phase 2 starts, the boss bar relabels to [P2] with a fresh countdown and the damage goal jumps — from 3.0M to 10.0M in the video — while the milestone payouts improve (Soul +10,000 and Legendary Fusion Shards +2 at that tier). Keep your tank alive through the phase transition and the better rewards follow. Exact goals and payouts are video-era values; expect tuning in later updates.
Phase 2 runs its own countdown and raises the damage goal to 10.0M, while the milestone payouts improve with it.
