The spawn points of mobs in Veteran Maelstrom Arena is shown in the figures below. Each round is divided into subrounds and the order goes red, blue, black/white, purple, green. Consult the table under each map for the abbreviation. For the first three rounds, I have included mob health, spell resistance and raw damage. Spell resistance and raw damage was calculated using equations in Sorcerer Arithmagic. Raw damage refers to damage before mitigation and any champion point effects like Elemental Defender or Hardy. I'm not totally convinved of the benefits of determining all mob spell resistance and raw damage hence why I stopped at the Drome of Toxic Shock. Perhaps if someone could provide a really good reason of what the data could be used for I will determine the spell resistance and raw damage of mobs in later stages.
