How long is a GCD in RS3?

One global cooldown (GCD) is 3 game ticks, 1.8 seconds. A game tick is 0.6 seconds, so a rotation of 10 abilities in a row takes 18 seconds.

How does adrenaline work after the combat changes?

Basic abilities build adrenaline, most by 9%. Enhanced abilities spend some (often 20–25%), and ultimates spend 60% or all of it. The bar holds 100%. The builder adds and spends it press by press, so you can see where a spender comes too early.

What does a cooldown conflict mean?

The ability is pressed again before its cooldown has run out, so in game nothing would happen. The builder marks the press and tells you the tick it is ready again; add a wait or move it later.

Is this a PvME rotation builder?

It writes rotations the way PvME guides do, ability names joined by arrows, so you can paste one into Discord or a guide. Share links keep the whole rotation in the address, so nothing is stored on our side.

Does it work with Alt1 or Rotation Master?

No, this runs in the browser and does not read your game. Use it to plan and share a rotation; an Alt1 plugin can then help you press it in game.

Where does the ability data come from?

From the RuneScape Wiki's ability pages, checked 2026-11-13. Removed abilities from before the combat changes are left out.

How to use the rotation builder

Pick a combat style and tap abilities in the order you press them. Each press lands one GCD (3 ticks, 1.8 seconds) after the last.
Tap a press on the timeline to move it, remove it, add wait ticks (for a channel or a boss mechanic), or put it on the same tick as the press before (for off-GCD moves such as Surge).
Set the adrenaline you start with. The chart under the timeline shows the bar after every press; a spender you cannot afford, or an ability still on cooldown, is marked in amber.
Copy the share link to send the exact rotation, or copy it as text for a Discord message or a guide.

Adrenaline and cooldown basics

Since the combat changes, abilities fall into basics, which build adrenaline, enhanced abilities, which spend some of it, and ultimates, which spend 60% or all of it for a big effect. A good rotation spends adrenaline as soon as a spender is ready and keeps the basics with the longest cooldowns rolling in between.

Every ability has its own cooldown counted in ticks. Greater versions share a cooldown with the ability they upgrade (Fury and Greater Fury), so the builder counts them as one. Pressing an ability before it is ready does nothing in game, which is why the builder flags it rather than letting it through.

Ability data: the RuneScape Wiki, checked 2026-11-13. Channelled abilities and effects such as buffs and stacks are not modelled; add wait ticks where a channel takes longer than a GCD.
