SoulLock's timers run on your real in-game clock rather than a broadcast feed, so they do not drift behind the match. Start them when your game begins, or set them to a match already in progress, and sound alerts warn you before the urn, the powerup buffs and the other timed objectives.
The desktop app draws the timers over Deadlock itself. The overlay puts each player's rank badge under their name in the top bar, and alignment mode shows numbered markers 1–12 so you can nudge the badges under the nameplates — easiest to do in a bot match in borderless or windowed mode.
Filling pie timers can be painted over the objectives on Deadlock's bottom-right minimap. Alignment mode marks all 43 spots as rings so you can match the centre, radius and rotation to the game's minimap, with a 180° flip for the other side.
Soul Urn. The first urn spawns at 10:00 and a new one every 5:00 after that. Since the June 30 update it appears at one end of the map and has to be carried to the opposite end; the runner is no longer revealed on the map, and the bounty decays if the urn sits on the ground too long, so the alert fires early enough to get a runner into position rather than at the spawn itself.
Powerup buffs. First spawn at 5:00, then every 5:00.
Jungle camps. Tier 1 camps are up at 2:00, tier 2 at 6:00, and tier 3 and the sinner's sacrifice boxes at 8:00. Respawn times were measured from live matches rather than copied from a wiki: roughly 90 seconds for small camps, 5:00 for medium and 6:00 for large. The map view tracks all 43 camps, and with the desktop app the ones that have actually been cleared show a filling ring back to their respawn.
Unstable Rift. The rift is the one objective no schedule can pin down: it opens in a random side lane roughly every seven minutes, with the first one around thirteen minutes in, and it stays open for exactly sixty seconds. The game announces it twenty seconds before it opens. The desktop app reads the forming rift directly and names the lane about twenty seconds before that announcement, which is the difference between rotating early and arriving to a capture already in progress. In the browser, without the desktop app, the card can only show the expected window.
Mid-boss. Killing the mid-boss grants the Rejuvenator, which lasts three minutes; the timer counts that window down so your team knows exactly when the enemy can respawn again normally.
In the browser the clock is predicted from when the match started and corrected from the broadcast, which runs about 24 seconds behind the game. The desktop app instead reads the match clock the game itself displays, so it is accurate to the second from the first moment and, because it is the game's own value, it freezes during a pause and resumes without drift.
Timers run in the browser; the in-game overlay and live match clock need the Windows desktop app.
