Move: WASD / arrows, or drag on the screen (the joystick appears under your finger).
Your abilities and items attack on their own. Your focus: keep moving, pick up XP, don't get surrounded.
Neutral camps sit still until you come close, then chase you as far as their camp's edge — hit them first and they chase further. A camp's pennant shows its size: 1–3 pips for small, medium and large, a skull for ancient. The bigger, the harder. Every minute, empty camps fill again.
The map is Dota's 7.40 map: the bases and parts of the jungle sit on high ground, and cliffs can only be climbed by the stairs.
Runes appear on their minute: power runes every 2 minutes in the river, bounty every 3, wisdom every 5.
Day and night swap every 2 minutes. Roshan changes pits at dawn and dusk. At night your vision shrinks and more monsters come.
Shop: stand at the shop by the fountain or a secret shop. A TP scroll takes you home to the fountain (T).
Levels 6, 12 and 18: your ultimate unlocks and levels up, and fires on its own like your signature. Max level is 30.
A level-up is a skill: Q, W or E. As in Dota, a skill's level is held to the hero's (level 2 needs hero level 3), so you can't stack one skill. Talents at 10, 15, 20 and 25. Items are bought at a shop, or dropped by neutral camps and chests.
Monsters, neutral camps and bosses grow with your level and the clock — Endless turns brutal after minute 10.
Elites (gold ring) drop a chest: free upgrades, no pause. Bosses change pattern at 75%, 50% and 25% health.
Dash: Space/Shift or the Dash button — a quick burst, untouchable while it lasts, 4-second cooldown. Use it to get out of a boss's red circle. Blink Dagger (shop) turns it into a longer blink on a shorter cooldown. R rerolls the level-up cards.
