m_Combo

m_Combo is an encoded uint32_t array containing SpellChainEffectsRec::IDs, it is the predecessor of m_SpellChainEffectID. This is stored in the DB as the byte representation of this array converted to a string.

The client parses this data by reading, decoding (CLightning::DecodeChainEffectsID) and validating each uint32_t one at a time. Reading will cease if one of the following conditions occurs:

  1. All field data is read
  2. An invalid SpellChainEffectsRec::ID is found
  3. 12 SpellChainEffectsRec::IDs have been read (additional data is simply ignored)

Note: It appears any referenced records without a valid and accessible m_Texture will be skipped

uint32_t CLightning::DecodeChainEffectsID(uint32_t value) {
   return (
      ( value & 0xFEFEFEFE)        | 
      ((value & 0x08000000) >> 04) | 
      ((value & 0x04000000) >> 11) | 
      ((value & 0x40000000) >> 14) | 
      ((value & 0x02000000) >> 18) | 
      ((value & 0x20000000) >> 21) | 
      ((value & 0x10000000) >> 28)
   ) & 0xFFFFFF;
