Physical Qualities
Magical Qualities
Absorbs fire elemental damage while Magma Hoplon shield is up. Orthrus casts Fire III-V exclusively to heal itself this way, and power up Acheron Flame.
Orthrus is almost immune to Light and Dark magic, you should attempt to fight Orthrus on Earth-Iceday to potentially avoid having spells like Dispel/Flash/Kurayami/Threnody as your !!trigger. The real danger in fighting Orthrus is facing Firaga IV followed by Acheron Flames. Stun one or the other if you can, or interrupt Firaga IV with a critical hit weaponskill.
When Orthrus does the Howling (animation), it seems to reset most Enmity.
Orthrus's Howl also grants him an intimidation effect for a short period of time(~15 second)
Critical Hits interrupt Orthrus from casting on a fairly consistent basis.
Due to his casting Blaze Spikes and using Magma Hoplon on a very regular basis, he will have spikes most of the fight. These can be negated by Atma of the Brother Wolf (if you have fought Orthrus before) and Phalanx II. This will also significantly reduce damage from fire spells and Gates of Hades
In Greek mythology, Orthrus (Orthros) or Orthus (Orthos) (Greek: Ὄρθρος; Ὄρθος) was a two-headed dog and a doublet ("brother") of Cerberus, both whelped by the chthonic monsters Echidna and Typhon.
