Hurricane is a two-handed threshold Attack ability that requires level 55 Attack to use. When activated, the player spins on the spot, dealing 66-219% ability damage to all targets in a 3x3 area of the player, including targets standing on the player's square. The player's main target is hit a second time for 84-161% ability damage; Hurricane deals an average of 265% ability damage to the player's main target. Targets standing behind walls are not damaged. Hurricane's cooldown is shared with Destroy.

Halberds, the noxious scythe, and the dragon rider lance increase Hurricane's range to 5x5 around the player. The dark ice sliver and dark sliver of Leng allow Hurricane to be used while dual-wielding, and when combined with either the dark ice shard or dark Shard of Leng gives it a separate cooldown from Destroy.

Hurricane is fairly similar to Quake, however:

• Hurricane deals far more damage due to its first hit having higher minimum damage and because it deals a second hit to the main target.
• Hurricane does not reduce the target's defence or raise their affinity values.

Explanation of Hurricane hits

The damage for the second hit of Hurricane is calculated differently than other abilities with multiple hits when a flat boost from having an increased Strength level is applied (such as from overload) and/or if the Precise perk is involved.

For simplicity, the player's ability damage is ignored with regard to the calculations for this entire section. This means that the flat boost part of the calculations will be shown, but only as a variable. If one wants accurate values, then instead of using damage values as percentages (as will be done here), the calculation should be the player's ability damage multiplied by the percentage to get the actual damage value.

• Let $d_{i}^{\text{fixed}}$ represent the fixed or minimum amount of damage associated with Hurricane hit $i$ where $i$ is either 1 or 2.
• Let $d_{i}^{\text{random}}$ represent the amount of damage between the minimum and maximum associated with Hurricane hit $i$ where $i$ is either 1 or 2.

The maximum amount of damage of either hit of Hurricane can be calculated by adding the two above terms: $d_{i}^{\text{fixed}}+d_{i}^{\text{random}}$. The damage that can be done will take on a random value between the minimum and maximum. This can be expressed as: $d_{i}^{\text{fixed}}+r\cdot d_{i}^{\text{random}}$ where $r$ is a real number randomly chosen between [0,1].

In terms of the contextually relevant buffs, the order in which buffs are applied are: base → Strength boosting prayer (such as Turmoil) → flat boost → Precise → Equilibrium → $\ldots$
The Dragon battleaxe special attack, Rampage, and the buff provided from the Gloves of passage or its enhanced version, Enduring Ruin, occur between the flat boost and the boost from Precise. However, their additional involvement does not differ between Hurricane hit 1 or Hurricane hit 2 and will therefore be ignored for this.

The damage from the flat boost is relevant when considering the ability damage of the player. However, for simplicity, the player's ability damage is ignored with regard to the calculations for this entire section. However, the term flat boost and level boost (only the difference in levels) will be used.

• The damage associated with the flat boost is calculated in the following way: ${\text{flat boost}}=4\cdot ({\text{boosted level - base level}})$. For example, if a player had a boosted level of 130 Strength while their base Strength level is 99, then the flat boost would be $4\cdot (130-99)=4\cdot 31=124$. This is applied twice, once to the fixed portion of damage and once to the random portion of damage. This is relevant for most ability calculations.
• The ${\text{level boost}}$ is only the difference in the player's boosted and base levels. That is, ${\text{level boost}}=({\text{boosted level - base level}})$.

For Hurricane hit 1, these values are $d_{1}^{\text{fixed}}=66\%$ and $d_{1}^{\text{random}}=153\%$. Hurricane 1 follows the expected calculations for buffs.

For Hurricane hit 2, they are calculated in the following way:

First, the damage associated with the flat boost buff which uses the values calculated from the damage associated with having an active damage boosting prayer (if no damage boosting prayers are active, then this is the base damage). The calculation involves certain values associated with Hurricane hit 1.

• $d_{2,{\text{flat boost}}}^{\text{fixed}}=d_{2,{\text{prayer}}}^{\text{fixed}}+\left\lfloor 10\cdot {\frac {d_{2,{\text{prayer}}}^{\text{random}}}{d_{1,{\text{prayer}}}^{\text{random}}}}\cdot {\text{level boost}}\right\rfloor$
• $d_{2,{\text{flat boost}}}^{\text{random}}=d_{2,{\text{prayer}}}^{\text{random}}+2\cdot {\text{level boost}}$

After this is the application of the Precise perk. Let $R_{\text{Precise}}$ be the rank of the precise perk. The calculation involves certain values associated with Hurricane hit 1.

• $d_{2,{\text{Precise}}}^{\text{fixed}}=d_{2,{\text{flat boost}}}^{\text{fixed}}+\left\lfloor \left(1+{\frac {d_{1,{\text{flat boost}}}^{\text{random}}}{d_{1,{\text{flat boost}}}^{\text{fixed}}}}\right)\cdot d_{2,{\text{flat boost}}}^{\text{fixed}}\cdot 0.015\cdot R_{\text{Precise}}\right\rfloor$
• $d_{2,{\text{Precise}}}^{\text{random}}=\left\lfloor {\frac {d_{2,{\text{flat boost}}}^{\text{random}}}{d_{1,{\text{flat boost}}}^{\text{random}}}}\cdot d_{1,{\text{Precise}}}^{\text{random}}\right\rfloor$

From here the Equilibrium perk is applied in the same way as it is with other abilities.

Trivia

• Although the ability's name is "Hurricane", the symbol is of a tornado.
• Hurricane used to deal 400% weapon damage, but due to a change in the beta which significantly increased damage of all weapons, this was reduced to 188% damage. With the release of Legacy Mode, Hurricane's damage was raised to a maximum of 219%. On 13 July 2015, a second hit was added to Hurricane that deals 84-161% weapon damage to the main target.
• Hurricane was known as Whirlwind in Jagex's test servers for the Evolution of Combat.
