The conquest point gained by winning the arena match need to buff more than the current point gained (currently 10 points). The removal of Labyrinth has made getting the right-side charm especially necklaces and ring to be painful since now the conquest point need to be shared with all equipment. For example, before the removal, we can gain atleast 1000+ ancient coins that's used exclusively for right side gear while still having arena for left side charm+you can farm eulogy for more. Now you can see we get less charm while also need to spread the conquest points across the equipment, though ideally you used the conquest points for right side charm since it isn't exactly farmable.

Even with selectively choosing the equipment strictly (only upgrade 28 gs and above), the charm drought is one you can't escape from in this game. I make this post because I rarely see anyone talks about it. The origin update is good and going into monthly Azmakalis raid without tokens is great but the things that have done to regular labyrinth is not exactly great since it basically does one time and it's done which made you wonder what the purpose of it now. Atleast before you can use it to farm for charms.
