Heat Sink Extended Description

Basic Description: "Redirects Fire moves. Absorbs them, ups highest Atk."

Extended Description (283 characters): Heat Sink redirects Fire-type moves targeting allies to this Pokemon. When hit by a Fire move, the attack is completely absorbed (no damage taken), and this Pokemon raises its highest attacking stat by one stage (Attack or Special Attack, whichever is higher at the time of absorption).

Technical Analysis

Core Mechanics

• Redirect Function: Uses redirectType = TYPE_FIRE to attract Fire-type moves
• Absorption: Uses onAbsorb with CHECK(moveType == TYPE_FIRE) to absorb Fire moves
• Stat Boost: Calls GetHighestAttackingStatId(battler, TRUE) to determine which stat to boost
• Result: Returns ABSORB_RESULT_STAT to trigger stat increase

Stat Selection Logic

The GetHighestAttackingStatId function compares:

• Current Attack stat (STAT_ATK = 1)
• Current Special Attack stat (STAT_SPATK = 4)
• Includes stat stage modifications in the comparison (includeStatStages = TRUE)
• Returns the stat ID of whichever is higher

Redirection Mechanics

• Only works in double battles where allies can be targeted
• Redirected moves are completely negated (no damage dealt)
• Cannot be bypassed by Propeller Tail or Stalwart abilities
• Does not redirect moves with the Snipe Shot effect

Battle Flow

1. Enemy uses Fire-type move targeting an ally
2. Heat Sink redirects the move to the Heat Sink user
3. Move is absorbed (no damage taken)
4. System determines highest attacking stat (Atk vs SpAtk)
5. That stat is raised by one stage
6. Ability popup is displayed

Interactions

• Breakable: Can be suppressed by abilities like Mold Breaker
• Stackable: Can potentially stack with other stat-boosting effects
• Immunity: Provides complete immunity to Fire-type damage when absorbed
• Priority: Absorption occurs before damage calculation

This ability is essentially a Fire-type version of classic redirection abilities like Lightning Rod (Electric) and Storm Drain (Water), but focuses on boosting offensive power rather than Special Attack specifically.
