Items: a leading * marks a 1.12 item carried over into the beta; no asterisk = a Classic Plus: Forever item (the demo, the deep dive, or beta build 1.60.1.69876). The Sources filter lists the Forever items by where they come from (C+ Quests, C+ Crafting ...), C+ Unsorted holding the ones with no source on record yet. Dimmed rows are Classic Era items the beta build does not contain. Re-itemized items carry their beta stat table, with the change in the tooltip note (crit 14 = 1%, hit 10 = 1%).
Talents are the beta build 1.60.1.69876 trees, every rank. Outlined talents are new or changed in Classic Plus: Forever (the tooltip badge says which). Hover any talent for its text; hold Shift for the original 1.12 text. A talent marked with an assumption warning has per-rank scaling the sim interpolated itself.
Abilities are the vanilla level 60 ranks except where Forever changed them: Mutilate (both hands x0.75 plus 17.25, +20% on a Poisoned target), Hemorrhage and Ghostly Strike, Flawless Execution (Eviscerate costs 25), Venom (+30% poison damage), Hack and Slash per hand (an off-hand sword or axe proc swings the main hand). Poisons are temporary weapon enchants. Each entry's tooltip says what the sim does with it.
Racials: Human +2% crit with swords and Dwarf +1% with maces on that hand only, Dwarf and Troll +5% vs Beasts, Gnome +5% maximum Energy plus Eureka!, Night Elf Elune's Light, Orc +1% with axes (rogues can use axes in Forever) and Blood Fury, Troll Berserking, Skyborne 1% haste and +5% vs Elementals with placeholder base stats.
Gear: every rogue-usable weapon (one-hand Daggers, Swords, Maces, Fist Weapons and Axes for either hand) and every Cloth or Leather piece, cloak, ring, neck, trinket and ranged weapon with a melee stat.
Blade Flurry with Adjacent Mobs above 0 copies every landed melee hit to one more target on its own STATS row.
In front of the target: a Target Attack Speed above 0 means it is hitting you, so you are standing in front of it - the target parries and blocks, a parry hastens its next swing, and the from-behind abilities are off.
Buffs: both factions can take totems and Blessings, and every raid buff is its improved version (Mark of the Wild 16, Blessing of Might 222, Strength of Earth and Grace of Air 88, Windfury Totem 409).
Changelist: the note on first load lists the changes to this page that affect DPS outcomes; it comes back when a new entry lands.
