Iron Serpent

Type: Offensive Multiplier
ID: 588
Description: "Ups "supereffective" by 33%."

Core Mechanics

Iron Serpent boosts the power of super-effective moves by 33% (1.33x multiplier). This ability triggers when the user's attack has a type effectiveness multiplier of 2.0x or higher against the target, applying the damage boost on top of the existing super-effective multiplier for devastating effect.

Technical Implementation

The ability uses the onOffensiveMultiplier callback, sharing the exact same implementation as Winged King. It checks typeEffectivenessMultiplier >= UQ_4_12(2.0) and applies MUL(1.33) when triggered. The UQ_4_12 format represents fixed-point decimal values with 4 integer bits and 12 fractional bits.
