This build is nothing special, using the basic hybrid crit/status mods that go on several melees - what makes the [Orthos] good is its perfect blend of stats to fully utilize this build.

Combo duration mods such as [Drifting Contact] are unnecessary given the addition of Arcane Dexterity, equipped on one weapon it grants 7.5s and on two it grants 15s of combo duration, combine that with Naramons Power Spike and you will virtually never lose combo.

An example of a unique, very powerful Orthos build would be this one which I use for my Warcry Saryn - https://overframe.gg/build/103176/orthos-prime/saryns-warcry-orthos/
