All 20 Gear Sets, Effects and Boss Drops in OUTERPLANE

In OUTERPLANE, gear is a big part of what makes your heroes strong, and armor is where gear sets come in. A gear set is a group of armor pieces that share the same set effect. Wear enough matching pieces together and you unlock a bonus on top of the stats each piece already gives. Knowing how that bonus works and where each set comes from helps you decide which ones are worth chasing.

How OUTERPLANE Gear Sets Are Built

Each hero can wear three kinds of gear: a weapon, an accessory, and armor. Only armor works in sets, and the set effect is what separates one set from another. That makes the set effect the first thing to compare when you're picking one.

How Set Effects Activate: Two-Piece and Four-Piece Bonuses

A set effect turns on when you wear matching pieces. Most sets give one bonus for two matching pieces and another for all four. Some sets only have one of the two, and that changes how you can use them.

Revenge and Patience only pay off at four pieces, so a partial set gives you nothing. Swiftness, Weakness and Augmentation only have the two-piece bonus, so a matching pair is all you need. Checking which kind a set is before you build keeps you from wasting pieces.

What Set Effects Do in Battle

Set effects fall into two kinds. Some raise a stat all the time, such as attack, HP, defense, crit rate, speed, or resistance to debuffs, the harmful status effects that weaken your hero. These are the easiest to plan around because they never switch off.

The rest depend on the fight. Revenge raises attack as your own HP drops, Patience does the same for defense, and Swiftness does it for speed. Others reward a specific situation, like Pulverization against enemies in the Break state, Weakness against debuffed enemies, and Augmentation while your hero has a buff.

Some effects come with a cost. The Fortification Set from Unidentified Chimera cuts the damage from the first attacks your hero takes, but it also lowers your hero's own speed for a turn.

Where to Get OUTERPLANE Gear Sets

Armor sets come from the Ecology Study Special Requests. Each set belongs to one boss, Masterless Guardian, Tyrant Toddler, Unidentified Chimera, Sacreed Guardian or Grand Calamari, and every set in a group drops from that same boss.

Higher stages improve your chances at top-rarity gear, so clearing harder stages is how you improve your odds. It usually makes more sense to target the boss whose sets your hero needs than to chase every boss at once.

Which OUTERPLANE Gear Sets Matter Most

Speed is the set many players want first. Speed decides turn order and matters for any hero, in both PvP and PvE battles. The Speed Set comes from Unidentified Chimera, which is why that boss is often the first one players farm.

For attackers, Critical sets matter most. They raise your critical hit rate, or crit rate, and the ideal is 100 percent, so every hit is a critical hit and your damage stays steady. That's hard to reach early on, but the Masterless Guardian sets, which include Attack and Critical Hit, keep helping attackers from the early game through to the late game.

For arena fights, the Immunity Set from Grand Calamari is worth a look. It shields your hero from debuffs for one turn at the start of battle. The right pick still depends on the hero you're building, so check what that hero needs before you farm.

How Breakthrough Makes Set Effects Stronger

Breakthrough is how armor gets stronger after you own it, raising a piece from T0 up to T4. Set effects grow along with it, so a set at T4 gives a noticeably bigger bonus than the same set at T0.

Breakthroughs use materials, so it pays to decide which pieces matter most before you spend them. Fully upgrading the pieces your main heroes use makes more sense than spreading materials thin.
