How to Farm Shards Fast in Be The Final Boss (Video Walkthrough)
A frame-checked walkthrough of the Radex Tips shards route: what Fusion Shards are for, auto-battle gate farming, smart spending on mutated units, tier fusion, and the skill tree multiplier.
What this walkthrough covers
The video's core claim is simple: shards are the upgrade material that really pushes your army's combat power, while Coins and Souls handle unit unlocks and account upgrades. The fastest source it names is defeating enemies — the heroes attacking your castle drop materials including shards — so the whole routine hangs on keeping kills constant. That means auto battle left running in long sessions, your strongest team equipped, and steady pushes into stronger stages. On the spending side, the video argues for concentrating shards on the units you actually use, checking mutations before committing to a duplicate, and fusing low-tier shards up the Common to Rare to Epic to Legendary ladder instead of hoarding them. A skill tree with no direct shard output quietly multiplies all of it.
Where these facts come from
Every step here is drawn from the Radex Tips video "How to GET SHARDS FAST in BE THE FINAL BOSS Roblox" (4:47) and from frames we extracted and read ourselves; nothing comes from other sites. Where the video shows a UI element — the Auto ON badge, the Rare Fusion Shard item card, the skill tree nodes — the steps say so. Where it stays silent, we stay silent: the video names no drop rates, no per-kill shard amounts, and no fusion costs, so none appear on this page. One caution: the purple counter in the bottom-left of the frames climbs from 168 to 252 while farming continues, which fits the shard-gaining story, but the video never labels that counter, so we treat it as a footnote rather than evidence.

- 1
Know what shards are for before you farm
The video opens with the priority call: shards are mainly used to upgrade your units, and every upgrade makes a monster deal more damage and survive longer in battle. Coins and Souls help with unlocking units and improving your account, but shards are what push combat power forward — and as you progress, each next upgrade costs more, so consistent farming matters. The frame shows one Rare Fusion Shard drop card, the exact item the whole grind is for.

Farm the gate: defeat enemies with Auto ON
The fastest way to get shards, per the video, is defeating enemies — heroes attacking your castle drop valuable materials, including shards. Its recipe: keep your strongest team equipped, enable auto battle for continuous farming, stay active when possible, upgrade units so waves clear faster, and keep pushing into stronger stages with better rewards. The frame shows the Auto ON badge lit over a Wave 9 defense. AFK farming is the easy mode of the same loop: place your units around the castle, leave auto mode on, and favor one long session over constantly restarting battles.

Spend only on the units you actually use
Do not spend shards randomly on every monster you own. The video is explicit that upgrading your strongest, most-used units gives a much bigger power boost than spreading small upgrades across the whole collection — and whenever a summon beats a current unit, replace the weak one so farming speed stays high. Mutations raise the stakes: a unit with a powerful mutation like a Cursed variant is usually the better investment, and mutated units can outperform regular ones even at the same level. Compare duplicates before you commit shards.

Fuse low tiers into higher Fusion Shards
As you play, your inventory fills with weaker materials. The video's progression: Common shards fuse into Rare Fusion Shards, then Epic Fusion Shards, and later Legendary Fusion Shards. Converting lower tiers regularly keeps dead stock from piling up and builds the higher-quality shards you will need for stronger upgrades later. The video narrates this over regular gameplay and never opens a fusion screen, so exact fusion costs stay unknown.

Let the skill tree compound every session
The skill tree does not directly give you shards — the video says so itself — but its upgrades improve overall combat strength, which lets your team defeat enemies more consistently, complete more waves, and farm more drops. The frame shows the tree's hex nodes: Boss Attack, Boss Health, Coin Income, Population, Unit Damage, and an Auto Battle node beside the Summon Altar. The video's closing routine ties everything together: upgrade the skill tree, field your strongest team, run auto battle for long sessions, defeat as many heroes as you can, spend shards on your best units, fuse low tiers upward, and repeat.
The skill tree never drops shards directly — it makes every session clear more waves for more drops.
