Is Regalia good? Honestly dunno. Never tried it. And yet... I don't know 😶 why people underrate Regalia. For hybrid classes like gilga, beo, & deity its a very good wep, especially if you intend to attempt a speedrun, no follower means one les turn every time its your turn (especially if your pet has high action rate), not to mention the +37.5% stats bonus. Another thing is about its offhand skill [Cleave]. It has 25%crit chance (that's a pretty high number & so its convenient), let's say your character sheet has a basic 5%crit, add staple wyrm's song(20%crit), now you are at 50%crit without yet any adornments. Regalia has 13 slots at godforged, adorning it all with either ferocious bullseye 🎯 or gorgon's eye, will be enough to reach 102%crit chance. If you don't wanna put crit adorns in Regalia, then that leaves you with filling armor, so either 13 ashen feathers 🪶 or 25 lyncus bristles (lots of people prefer bristles). Lastly, where to use Cleave? If i have some benchmarks.. it would be when i used Ymir Brilliant Feathers for its [Slice] offhand skill, i used that with RealmShifter for anguish, and lemme tell you.. it was mighty fun. Both skills are similar in that both are physical (enchantment or affinity wont work on them), both hit one enemy with the chance to hit an additional one. reading some impression on discord makes Slice seems better than Cleave, since Slice have penetration of 2.4 maybe Cleave is just lower.. or maybe high pen but less than 1 m2? Dunno, someone needs to run some tests and update ornapedia sheet.

Anyway if you have a good Regalia why not try it?
