Red Text
Protect me, squire!
This review was machine-translated from the Japanese original. Numbers are checked against the original; if the wording reads oddly, the Japanese version is authoritative.
When the final armor segment breaks, a support drone “Shield Boi” that blocks enemy bullets appears, a Tediore-made shield. It is a summon-type that spawns a partner to take bullets for you at the moment of a pinch when the shield is fully depleted. Its characteristic is being able to “externalize” defense.
🧩 Origin of the red text “Protect me, squire!” is a famous line shouted by Claptrap in ‘Borderlands 2’ (quoted Borderlands Wiki in the “Blindsided” mission). It calls the player squire and asks for protection, a typical cowardly character line. The effect of this shield = summoning Shield Boi (the protective companion) matches perfectly.
What kind of shield? (Beginner’s perspective)
- Armor-type shield (Tediore-made). A typical Tediore “gadget summon” type
- At the moment the final armor segment breaks, it generates a support drone Shield Boi for 30 seconds
- Shield Boi positions itself to block enemy bullets, using a curved holographic shield to protect from both sides
- = When the shield is broken in a pinch, a bullet-blocking companion spawns; a summon-type shield
Unique effect (mechanics)
When the final armor segment is destroyed, generate a support drone Shield Boi (30 seconds). Deploy a curved holographic shield that blocks enemy bullets.
- In-game: Generates Shield Boi (Decoy) when the final segment is destroyed
- Web (Lootlemon): On final Armor Segment break, spawns a nimble Shield Boi support drone that lasts 30s. The Shield Boi positions itself to intercept enemy fire and projects a curved holographic Shield that blocks enemy bullets from both sides.
- Weakness: Shield Boi’s AI is unstable and in intense combat may not reposition quickly enough to block bullets (Lootlemon note). Whether its positioning works is a matter of luck (unverified)
Drop farming
| Drop Source | Rate | Notes |
|---|---|---|
| World Drop | (unverified) | No dedicated drop source. Farm by targeting world drops. |
