Aktaios can create two copies of himself that appear to deal similar damage to the original, but they die in one or two hits. He also has a weak version of the Volcanic Orb from the Earth Mastery. He can also summon two minor monsters to assist him. A more important ability is Sandstorm, which disrupts skills. His last and strongest ability is Light of Ra, which calls down a few rays of sunlight, dealing (very) high fire damage. The rays always hit the same spots, making them easy to avoid. On normal dificulty Light of Ra deals around 400 damage per tick with 60% fire resistance.
- Skill Disruption
The duplicates are not too dangerous as they can be killed in 1-2 hits. The Volcanic Orb is not very powerful, so if your fire resistance is low, an occasional health potion should be enough. The two bone scourges that Aktaios summons are very weak, not hard to kill. Decent skill disruption resistance will help with Sandstorm. If you stay away from the center of the chamber you can easily avoid taking damage from Light of Ra. High fire resistance (50-60%) will make this fight a piece of cake, even if you accidentally touch a ray of light.
