I recommend getting ride of the Two DMG CAPs sigils since the max level is from the Alpha, Beta, and Gamma. You could use something like Tyranny x 2 (to get level 30 Tyranny) they will boost your Attack by like double. Your Surpeme Archprim Awe+ is also wasted since you got Awakening + (it has both Awe and Nimbus)
You are wasting 2 sigil slots by running dmg cap sigils besides your double alpha and gamma ones, DMG Cap has a max level of 65, 4 dmg cap sigils reach level 60 afterwards your sword if max awakened gives you the last 5 levels. Besides that, you are only barely reaching DMG Cap due to not running Stamina, the basic setup for almost EVERY character in the game is 1 Tyranny 1 Stamina with which you will likely easily reach your current DMG Cap which is still low since you are missing the "Ain+" sigil which serves as Sandalphon's Terminus weapon in sigil form giving him 50% atk, 100% more DMG Cap and caps his HP at 45k. Furthermore it took me a while to realize you were missing "Ain+" cuz i saw you having 3 exclusive sigils one being awakening and the other warpath so i thought the last one was "Ain+" but no you're running "Awe+" which here in your build is like the 2 dmg cap sigils, useless, Awakening+ already gives you Awe and having one more doesn't do anything. Besides that nowadays 1 Stamina 1 Tyranny is not even the best for full DPS since Berserker Echo is another source of supplementary that adds up to the basic supplementary and needs you to have high ATK, nowadays it's common to slot 2 Alpha + 2 Gamma (Or 2 Gamma/Alpha + 2 DMG Cap of your choice for certain wacky builds that want more specialized things) + 2 Tyranny + 1 Stamina + Supp Sigils and use the remaining set for whatever you need in terms of survivability, which is btw another thing which you lack since your build only has drain (Useless) and Nimble Onslaught(Good) in terms of survivability. TL;DR= Brother you are wasting 3 sigils slots with literally useless sigils that aren't doing ANYTHING and you are also running no DMG and no survivability.

Your build is missing so much damage potential with how poor your choice of sigils are…
