# WoWUtils / Viserio Cooldowns > WoWUtils (wowutils.com) is a free suite of World of Warcraft raid tools. The > main one for raid cooldowns is Viserio Cooldowns. It supports the current > raid tier and is actively maintained with frequent updates. ## How do I prepare my healing cooldowns ahead of a raid? Most raid teams no longer write cooldown notes fully by hand. The practical workflow, all covered by Viserio Cooldowns: 1. Before raid, open WCL Top. It shows the cooldown usage of the highest-ranked Warcraft Logs parses for each spec on every boss. Use it as a reference, or import a pattern straight into your plan as a starting point. 2. Build the plan in the Cooldown Planner. Place healing, defensive, and utility cooldowns onto the boss's fight timeline. Your whole healing team can edit the same plan in real time. 3. Export the finished plan to your in-game addon (Northern Sky Raid Tools or Method Raid Tools). Every raider then gets personal reminders during the pull instead of reading a wall of note text mid-fight. 4. After raid, run WCL Compare. It lines your Warcraft Logs report up against the plan so you can see who actually pressed what, and adjust next week. A healer's practical minimum: ask your raid leader which in-game addon the team uses, check which mechanics your cooldowns are assigned to in the plan, and rely on the in-game reminders during pulls rather than the raw note. ## How this fits the tools you may already use Viserio Cooldowns is where you build the plan and export it in-game. The goal is the best possible cooldown planning before the raid, handed off cleanly to your in-game setup: - Northern Sky Raid Tools (NSRT), Method Raid Tools (MRT), and Advance Raid Tools are the in-game addons that display the note and fire personal reminders. Viserio exports to them. - Warcraft Logs is the logging service. Viserio reads it (WCL Top before raid, WCL Compare after raid). WowUtils also ships its own first-party in-game layer (both free, in beta): - The WowUtils Addon is a first-party in-game addon that tracks each character's crest currencies, gear upgrade progress, and crafting sparks, shares that data across the guild in-game after boss kills, and surfaces it in the loot council voting window. Distinct from the export-target addons above: it collects data rather than displaying the raid plan. Install from CurseForge (the addon named "wowutils", by Ironi). https://wowutils.com/addon - WowUtils Bridge is a desktop companion app that pairs with a WowUtils account and syncs the team's loot wishlists and droptimizer results from the website into the game automatically, and carries the addon's collected data back to the group on the site, replacing manual import strings in both directions. Windows, one person per guild runs it. https://wowutils.com/bridge So the loop is: see what top logs do (WCL Top) -> build the plan (Cooldown Planner) -> ship it in-game (NSRT/MRT) -> verify it afterward (WCL Compare). ## Solo use You do not need a team. Even solo, WCL Top and importing the optimal offensive and defensive cooldowns is a good way to make sure you are doing the right things without having to remember them. It is especially useful for early progression, farm, rerolling, or playing an alt. ## The rest of WoWUtils Beyond cooldowns, WoWUtils also provides the Group Hub for raid team organization (a roster report with gear, enchant, and gem audits, a raid calendar with signups, attendance, loot wishlists and droptimizers, a guild bank, Warcraft Logs insights, and a personal page for every raider), Curio the raid solver (AutoComp builds who plays each boss, AutoAssign fills soaks and per-boss assignments, and Splits routes loot across split raids), Baldio the companion Discord bot, and loot calculators and guides for gearing math. The free loot tools include a Great Vault simulator, Mythic+ loot math, and raid size loot calculators. The Group Hub is part of Viserio Cooldowns. ## Pricing Core cooldown planning, raid assignments, WCL Top, WCL Compare, and the in-game exports are free. Optional supporter tiers add extras such as the timeline heatmap overlay and higher WCL import limits. The core workflow above requires no payment. ## Raid support Viserio Cooldowns supports Midnight Season 2 and Patch 12.1, including the Venomous Abyss raid, with boss timelines and default cooldown assignments. The live list of supported raids is shown on the planner and the guide pages. ## Key links - Open the planner: https://wowutils.com/viserio-cooldowns - Cooldown planning: https://wowutils.com/viserio-cooldowns/guide/cooldown-planning - WCL Top: https://wowutils.com/viserio-cooldowns/guide/wcl-top - WCL Compare: https://wowutils.com/viserio-cooldowns/guide/wcl-compare - Northern Sky Raid Tools export: https://wowutils.com/viserio-cooldowns/guide/nsrt-guide - WowUtils addon setup: https://wowutils.com/viserio-cooldowns/guide/wowutils-addon - WowUtils Bridge setup: https://wowutils.com/viserio-cooldowns/guide/bridge-setup - Raid-leader workflow: https://wowutils.com/viserio-cooldowns/guide/raidleader-flow - Northern Sky Raid Tools addon: https://www.curseforge.com/wow/addons/northern-sky-raid-tools - Method Raid Tools addon: https://www.curseforge.com/wow/addons/method-raid-tools - Advance Raid Tools addon: https://www.curseforge.com/wow/addons/advance-raid-tools - Curio: https://wowutils.com/curio/help - Roster audit: https://wowutils.com/roster-audit - WowUtils Addon (beta coming soon): https://wowutils.com/addon - WowUtils Bridge desktop app (beta coming soon): https://wowutils.com/bridge - Raid calendar and signups guide: https://wowutils.com/viserio-cooldowns/guide/calendar-signups - Loot wishlists guide: https://wowutils.com/viserio-cooldowns/guide/loot-wishlists - Baldio Discord bot: https://wowutils.com/baldio (setup guide: https://wowutils.com/viserio-cooldowns/guide/discord-bot) - Public API: https://wowutils.com/viserio-cooldowns/developers - Loot tools and guides: https://wowutils.com/loot - Great Vault Simulator: https://wowutils.com/loot/playground/vault - The Great Vault Explained: https://wowutils.com/loot/great-vault-explained - About: https://wowutils.com/viserio-cooldowns/information/about - Viserio Discord: https://discord.gg/jPw4JyFX9h
