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: the weapon imbue is the temporary enchant of the hand (Windfury Weapon: 20% chance of 2 extra attacks with 333 attack power; Rockbiter +653 attack power; Flametongue 28.1 Fire per second of weapon speed), Stormstrike on cooldown, Earth Shock when the set mana would remain, Lightning Bolt at the set Maelstrom Weapon stacks (5 at 5/5 = instant and free), Lightning Shield only when the target is hitting you, Rage of the Farseer when ready. Maelstrom Weapon's proc chance is a setting (20% by default).
Mana: base 1520 plus 15 per Intellect, 15 + Spirit / 5 every 2 sec (the five-second rule; Improved Stormstrike keeps half of it for 15 sec), mp5 from gear, Blessing of Wisdom and Mana Spring Totem under Buffs, a Major Mana Potion entry.
Racials: Orc +1% crit with axes on that hand and Blood Fury, Troll Berserking and +5% vs Beasts, Tauren +1% hit, Dwarf (the Alliance shaman) +1% with maces and +5% vs Beasts, Skyborne 1% haste and +5% vs Elementals with placeholder base stats.
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.
