Ice Rune

**Ice Rune** is a Runelord skill in *Octopath Traveler*.

## Effect

Applies the  **Ice Rune** buff to the **user** for **3 turns**.

For the duration of the effect, your standard attacks and physical attack skills are modified so that each attack will be followed by the skill *Icy Pursuit'*, dealing damage to every target struck by the original attack. The follow up attack is made with a +100 hit modifier. Multi-hit attacks will only trigger the follow-up attack once. Additional applications of the same buff onto the same target stack the remaining duration additively, up to a maximum of 9 turns.

Only one Elemental Rune may be active on a target at one time. Casting another rune overwrites the previous and resets the duration.

**Boost**: Adds **+2 turns** to the duration per boost, to a maximum of 9 turns.

## Formula

*Icy Pursuit* Damage = **8** x [*Attacker E.Atk* - (*Target E.Def* x **0.275**)]

The attack uses your E.Atk value with the weapon you have currently equipped when the Pursuit is invoked, i.e. the weapon you attacked with. This is in contrast to normal elemental attack skills, which use the weapon you have the highest E.Atk value with.

### Other Multipliers

* All damage scales with the level of the attacker (see **Level Multiplier**)
* All damage has a random multiplier (from x0.98 to x1.02) applied to it for each hit
* Critical hits deal x1.25 damage.
* Hitting an enemy with a weakness to Ice deals x1.3 damage (or x1.5 with ); hitting a Broken enemy instead deals x2.0 damage
* The  **Increased Elemental Attack** buff on the attacker or the  **Decreased Elemental Defense** on the target increases damage by x1.5; with both, the total multiplier is x2.25
* Having an  or  equipped increases damage by x1.3; with both, the multiplier is x1.6
