I'm thinking we should get a glossary made for new players who're wondering what certain commonly-used terms mean.
Particularly important terms will be underlined.
*s: Stars are used to represent the difficulty settings in Bastagant quests. 3 stars requires all five treasures, and is the most difficult. 2 stars requires three treasures, while 1 star requires any number. 0 stars requires that you grab NONE of the treasures, and gives no rewards whatsoever.
ABR: Auto Beam Rifle, a popular AIR-type weapon available in the rt shop.
AG: Aquila Girl. Also known as "Ah-chan".
Alphag: Moving Burst bots (usually AIR, but can be other types as well) known for their insane damage output. AIR-type Alphags typically use Air Loop.
Amatorius: A Moving Burst Amateus build popularized by Tori.
Berz: Short for Berzelius, one of the Bastagant bosses. Usually done on 1* or 2*, the former for just materials and the latter for materials and experience.
Chivalry: Shorthand for Chivalry Slash, an attack used by Elisalotte that recovers her WB gauge.
CV: Crimson Veil, a status buff caused by Dracken and Ivis's BD subweapons as well as its respective Revenge Tune. During its duration, you can't be stunned and you glow red.
DBMG: Double Beam Machinegun.
DG: Destructor Girl.
EIW: Enhance Internal Weapon cart.
Fat: An adjective used to describe a bot or part with an unusually large hitbox. It's best to avoid this.
Frac: A Bastagant boss. Formerly occasionally farmed in hopes of getting Stardust Cannons and Custom Shotguns. With these two weapons in UC gara, he is hardly fought anymore.
Geo: Geograsis. Comes in two types: Geograsis F-Type (AIR) and Geograsis G-Type (LND). The Mod versions of the two come with Anti-Ground Missiles and a Pile Bunker in their arms, respectively.
Geobunker: Geograsis G-Type Mod's AM subweapon, a powerful pilebunker that has a chance of igniting enemies.
Hopper: A bot with Short Boost and (most of the time) Quick Land. Hard to hit.
Internal: a. See EIW b. A weapon that is locked to a bot's core.
K-shield: A deployable shield subweapon that two AMs have that disables use of the space bar while active. Hopping is still enabled. The Lancerlot version has 180 hp (making it the most durable shield in the game), while the Ritter Lazflamme version has 40 (effectively rendering it useless).
Lagkun: A Jikun Hu or Jikun Long player who spams their BD subweapons and lags a lot, causing them to teleport.
MB Air: See Alphag.
