[ShadowzLmao2]

Ping or DM me on discord to lmk when one or more of these have been PR'd so i can edit them out
In case you're wondering about battle_ai_switch_items, that has already been looked through by me and battle_ai_main has been looked through and outside of the TODOs it is fine

Steelsurge is not included in IsHazardMoveEffect

bool32 IsSemiInvulnerable(u32 battlerDef, u32 move)
{
    if (gBattleStruct->commandingDondozo & (1u << battlerDef))
        return TRUE;
    else if ((!gMovesInfo[move].damagesAirborne && gStatuses3[battlerDef] & STATUS3_ON_AIR)
            ||(!gMovesInfo[move].damagesUnderwater && gStatuses3[battlerDef] & STATUS3_UNDERWATER)
            ||(!gMovesInfo[move].damagesUnderground && gStatuses3[battlerDef] & STATUS3_UNDERGROUND)
            ||(gStatuses3[battlerDef] & STATUS3_PHANTOM_FORCE))
        return TRUE;
    else
        return FALSE;
}

Refactored IsSemiInvulnerable

Request: Change the ShouldSet[insert weather] functions to also check if a different weather is up and the opponent is using it
Also: Remove TYPE_STEEL and TYPE_GROUND from set sandstorm and TYPE_ICE from hail as they do not benefit from the weather

Why does HasThawingMove exist when you can just run CHECK_MOVE_FLAG(thawsUser)?

Make IsUngroundingEffect check for Skill Swap and Levitate on the opp

Added Sleep Talk in the sleep check in both functions

Added a check for a special move if the user has quick feet (pointless to burn if it halves your damage, not worth speed), can be argued that in a double battle with support moves or just hazard moves the added code should be removed

Request: Have accuracy check if the user has any inaccurate moves in the image below

For future reference: in the image below, only check for magic bounce
It has been changed to include magic coat

Not tested, worth looking over: Added punching glove
