--Once you reach the bottom, go forward, take a right and keep going past a room with rats until you reach a bigger room with a ladder.
--From this point on, know that there are plenty of enemies in each area mentioned below.
--Take the ladder down, and activate the Underground Roadside Site of Grace in a room to the right of this location.
--Once activated, take the ladder down on the second opening to the right in this room.
--Once you reach this new area, take the pipes to the right, and follow the wooden areas until you reach a doorway with a set of stairs inside.

Tips to Defeat Mogh, the Omen
If you want to have a better chance of defeating this boss, you can get the Mogh’s Shackle item for this fight.
This item will pin Mogh to the ground and leave him open for attacks. You can use this item twice, and if you are quick, you can use these instances to land some heavy damage on Mogh.

Best Damage Type Against Mogh, the Omen
Fire is not effective against this boss (just 6% of effective damage), but the following types of damage have a 53% effectiveness against Mogh, the Omen in Elden Ring:
Regarding physical damage, Standard, Slash, Strike, and Pierce damage all have an 88% of effectiveness against Mogh.

Boss Battle Strategy---Attacks Patterns
--This boss has plenty of Blood Flame and Blood Claw abilities, so you need to make sure you dodge those as Blood Loss can accumulate fast and cause massive damage!
--Make sure to take some Stanching Boluses to alleviate the Blood Loss in case you are hit.
--Mogh’s attacks are a little slow. He will start an attack movement, but the real hit comes in later due to its slow animations. Taking this into account, once an attack animation starts, do not immediately roll! Take just a fraction of a moment, anticipate the attack, and then roll.
--Mogh raises his hand to reach a portal; this indicates an upcoming Blood Flame rain attack. Whenever this happens, get some distance and prepare to dodge in case he throws Blood Flame at you.
--Keep an eye on Mogh’s right-hand movement, as it will indicate attacks with his trident. The trident is not what you want to dodge; it is Mogh’s hand! Once you see his hand is coming at you, it is time to dodge!
--Trident attacks are somewhat delayed, so wait just a fraction of a second to dodge them. Also, keep in mind these attacks cover a great range, and sometimes distance is not enough to avoid them, be prepared to dodge.
--Mogh usually follows a three-hit pattern with his trident, so be prepared to dodge multiple times in a row.

How to Get Damage In
--Sometimes when Mogh does his overhead slam, he might get stuck in a pillar. This does not happen all the time, and it is hard to predict. Nevertheless, it is the perfect moment to get in one or two hits.
--Get very close to Mogh and use Mogh’s Shackle item. This will pin him to the ground, allowing you to get several hits in. You can do this twice during the boss battle.
--You can summon Spirit Ashes and help from other players for this boss fight if you need an extra hand. Here are the best Legendary Spirit Ashes in Elden Ring!
--Mogh does a thrust attack with his trident. This move leaves him open for a couple of hits.
--You can also land a few hits after the third trident attack in his combo if you are close enough.
--Since Magic is somewhat effective against this boss, using ranged spells (not fire ones) is a good idea.
