Glossary

The words the site uses, each in a line. The longer versions are on How to play and How scoring works.

Draft: One run of the game: a random raid boss, one item taken from what it drops, repeated until every slot is full.
Slot lock: Taking an item locks its slot for the rest of the run. A better helm six bosses later changes nothing; your head slot is done.
Reroll: Skip the boss on the board and draw another. You get three a run; spend them on a board with nothing for you, not on a board with something.
Pity: When a boss drops nothing you can use, the board offers a consolation blue instead. A pity item fills the slot like any other and is marked as pity on your results.
Two-hander: One weapon that fills both the main hand and the off hand. Taking one closes two slots with one pick, which ends a Standard run a roll early.
DPS: The model's estimate of what your drafted set does in a fight, from stat weights checked against WoWSims. A relative figure for comparing sets, not a promise about the game.
Parse: Where your run's DPS sits against everyone else's runs on the same spec, as a percentile. A 90 beat nine in ten of them. The number on your results page and on the boards.
100: A fixed bar per spec, not "beat every run". Reach it and you have a 100 whatever anyone else does that day.
Score: How well you drafted, as one number: the precision of your picks against what each board offered, and the rarity of what you ended up wearing. Two runs with the same parse can have different Scores.
Best in slot: The best item the model knows for a slot, or the best whole set it can assemble for a spec. The spec guides list both. Every results page shows your set as a share of that ceiling.
Stat weights: The value of one point of each stat to a spec. The board colors an item's stats by them; the spec guides give the order.
Hit cap: The amount of hit past which more is worth nothing or much less, depending on the spec. Shown on your character sheet during a run.
Tier set: A class's raid armour set. Wearing more pieces of one earns a set bonus that the model values; the Zul'Gurub class sets earn a smaller one.
Zone drop: An item with no single boss. It belongs to a raid's shared pool and can appear on any board in that raid.
Standard: The main mode. Your own random boss order, three rerolls, a full set, a parse. Play as many as you like; the boards keep your best per spec.
Daily: One shared board per spec per day: everyone drafts from the same twenty bosses in the same order. One run per spec, and the day's board ranks only that day.
Day total: Your Daily score for the day: your best five spec boards added together. Nothing beyond five is added.
Streak: Consecutive days with a Daily run. Practice runs on past days do not extend it.
Practice run: A supporter's run on a past Daily board. It never counts for a leaderboard, a streak or a badge.
Duel: A series of legs against one opponent on a target dummy, both drafting on the same terms. Neither side sees the other's leg until both are in. Duels stay off the boards and off the parse curves.
Leg: One run inside a duel. The challenger sets how many legs a series is when the duel is made.
Month: The board's season. Standard boards run a calendar month, and a finished month is final: nothing added later moves it.
Weights version: Every run records the version of the stat weights it was scored under. A run is never rescored; when the weights change, the old version stays on the board if the change was small.
Content version: The build of the item and loot data a run was drafted from, recorded on the run for the same reason.
Recruit link: Your share links carry a code. Friends who sign up through it are counted on your profile.
Icon: A small mark worn beside your name on the boards and in the header, earned by badges or by supporting the site. You choose which to wear.
Badge: An achievement on your profile: a 100 on a spec, a full clear of a Daily, a duel record, a BlizzCon visit. A badge applies from the day it ships, never backwards.
Supporter: A Patreon patron. Supporters get the supporter badge and icon, unlimited username changes, their own channels in the Discord, and can play past Daily boards as practice.
