/* DOCUMENTATION: Break-Shield spells
    Break-Shield spells can be classified in three groups:

        - Spells on vehicle bar used by players:
            + EFFECT_0: SCRIPT_EFFECT
            + EFFECT_1: NONE
            + EFFECT_2: NONE
        - Spells cast by players triggered by script:
            + EFFECT_0: SCHOOL_DAMAGE
            + EFFECT_1: SCRIPT_EFFECT
            + EFFECT_2: FORCE_CAST
        - Spells cast by NPCs on players:
            + EFFECT_0: SCHOOL_DAMAGE
            + EFFECT_1: SCRIPT_EFFECT
            + EFFECT_2: NONE

    In the following script we handle the SCRIPT_EFFECT for effIndex EFFECT_0 and EFFECT_1.
        - When handling EFFECT_0 we're in the "Spells on vehicle bar used by players" case
          and we'll trigger "Spells cast by players triggered by script"
        - When handling EFFECT_1 we're in the "Spells cast by players triggered by script"
          or "Spells cast by NPCs on players" so we'll search for the first defend layer and drop it.

spell_gen_feign_death_all_flags applies all 3 flags

spell_gen_feign_death_no_prevent_emotes applies no UNIT_FLAG_PREVENT_EMOTES_FROM_CHAT_TEXT

/* DOCUMENTATION: Charge spells
    Charge spells can be classified in four groups:

        - Spells on vehicle bar used by players:
            + EFFECT_0: SCRIPT_EFFECT
            + EFFECT_1: TRIGGER_SPELL
            + EFFECT_2: NONE
        - Spells cast by player's mounts triggered by script:
            + EFFECT_0: CHARGE
            + EFFECT_1: TRIGGER_SPELL
            + EFFECT_2: APPLY_AURA
        - Spells cast by players on the target triggered by script:
            + EFFECT_0: SCHOOL_DAMAGE
            + EFFECT_1: SCRIPT_EFFECT
            + EFFECT_2: NONE
        - Spells cast by NPCs on players:
            + EFFECT_0: SCHOOL_DAMAGE
            + EFFECT_1: CHARGE
            + EFFECT_2: SCRIPT_EFFECT

    In the following script we handle the SCRIPT_EFFECT and CHARGE
        - When handling SCRIPT_EFFECT:
            + EFFECT_0: Corresponds to "Spells on vehicle bar used by players" and we make player's mount cast
              the charge effect on the current target ("Spells cast by player's mounts triggered by script").
            + EFFECT_1 and EFFECT_2: Triggered when "Spells cast by player's mounts triggered by script" hits target,
              corresponding to "Spells cast by players on the target triggered by script" and "Spells cast by
              NPCs on players" and we check Defend layers and drop a charge of the first found.
        - When handling CHARGE:
            + Only launched for "Spells cast by player's mounts triggered by script", makes the player cast the
              damaging spell on target with a small chance of failing it.
