Before beginning, there are a few things i would like to mention about this guide:
1) This guide is made for players that want to farm OGH instance with a LOW BUDGET
2) Spending more on equipment = gives you more comfort while farming the instance
3) This is a long guide (be prepared to read a lot)
4) This guide is not perfect and requires practice on certain stages. (you will still die / fail the instance if you are not careful)
Need to be Hero to enter the Instance
Royal Guard (doesn't matter what hero level you are)
Agi: 195 Atk Spd
Skills you will need:

Solar Sword (guranteed life steal) buy atleast 4-5 of it from the zeny mall (@warp ayo_in01 ). If they get broken you will have a spare

Before proceeding to this part you should read up on DRO Wiki OGH instance walkthrough to have a general understanding of the map and monster information
You will also need Macros for spamming Grand Cross / Sacrifice + Cloaking Combo
You will also need the Auto Pot Macro for spamming Mastella (If you have this, instance is do-able without creed helm)
The instructions are provided at DRO wiki.
1000-1200 Mastella Fruit (purchase with merchant's discount skill to lower cost)
Shadow Scrolls for Amdarais Boss
Bubblegum x2 (to increase drop rate of coagspells)
Token Of Siegfried (you can buy them for insurance,not necessary when you have more experience)
If you have read the DRO wiki walkthrough you will know that there are
3 Phase before Corruption Root Boss + 2 phase before Amdarais Boss = total 7 Phase including boss stage
#1) Upon entering the instance and talking to Varmundt & Heinrich, stay on the left side of the map to prevent getting slaughtered by mass spawns of abysmal knights and khalitzburgs
#2) Pre-Cast Full Chemical Protection (10minutes duration) before entering (you can use dual client to buff yourself with FCP)
#3) Be as efficient as you can so you can clear phase 2 before your FCP expires
#4) Use bubblegum before phase 1 begins
#5) turn on vanguard force
A portal will appear on the left side once you have finished talking to the NPC Varmundt
Equip your 100% ACD returner set, turn on auto pot and clear the monsters with grandcross.
This should be quite easy as most of the monsters are undead. Prioritize on killing Chamberlain & Corrupted Monk as they are undead.
Rinse and repeat until the NPC appears, talk to the npc and proceed to phase 2.
Make sure your FCP has not expire and proceed to clear those bugs that can FULL STRIP you.
Once you have cleared those bugs you can start to clear those zombies.
In the event if your FCP has expire, dont worry. You can still clear phase 2.
Move around the map and clear those zombies without triggering those FULL STRIP bugs.
Rinse and repeat until the NPC appears, talk to the npc and proceed to phase 3.
For this part, there are two monsters Raydric Knight and Archer.
Killing Raydric Archers is easy, just equip Strong Shield to prevent Archer's knockback and spam that cloak & sacrifice combo
Raydric Knight is more challenging as it can break your helmet, armor and shield. At phase 3, your FCP probably has expired but dont worry.
What you need to do is lure those knights to a safe zone and kill them seperately.
The Sacrifice and Cloak combo is important here cause the Knights cant break your armor when you are Cloaking. Also make use of you +4 range advantage.
This part will be slower compared to Phase 1 & 2, just becareful not to break your armor while clearing those Knights. With experience this part will become a whole lot easier.
You can also use the Inspiration Buff at the beginning of phase 3 to boost your damage. The cooldown will be refreshed when you have reach Phase 4.
Rinse and repeat and you will enter Phase 4, Corruption Root Boss
Phase 4 - Corruption Root Boss
Basically this stage is pretty easy for RG cause of the +4 range.
Make sure you are at the max attack range when hitting Corruption Root Boss to prevent getting nuked by Esma.
The boss has 1.6B HP, so phase 4 should take about 5-9minutes depending on how much HP gear you have.
Make sure you have the optimum delay for you Sacrifice & Cloaking combo so you can maximize damage. Also, turn on Inspiration when the cooldown is ready.
(If done right, you can out-damage an Elite RG Lv4 that doesnt use Sacri & Cloak combo)
Once you are done, talk to the npc and collect your reward. Proceed to Phase 5.
Phase 5 (Agony Knight Mini-MVP)
For this part there are few things that you need to take note on,
1) Always wear Demihuman reduction gear when there are Abysmal Knights near you. They can do 1.5m damage x5, if you are not wearing redux gear.
Solution: use returner's helm & returner's shield
2) Use cloak to seperate Raydric Knights from other monster. Raydric knights cant detect Invisibility.
3) If cloaking fails, use the luring technique to seperate them. Raydric Knights have higher movement speed and will outrun other monsters.
Once they are seperated, kill it with sacrifice & cloak combo. You should also do this with Raydric Archers.
4) For Bloody Murderer, Khalitzburg & Abysmal Knights, lure them in a group with DemiHuman Redux Gear+ Tao Gunka Armor with Ghostring scrolls + deviling garment
You should be able to tank them easily. Once grouped together, spam grandcross and clear them.
5) Try to lure without getting caught by Raydric Knights (They can break your armor if you are not careful when luring)
6) Rinse and repeat until the Mini MVP spawns.
7) Equip shield with alice card, tao gunka with ghostring scroll + deviling garment
8.) Seperate the MVP from the other spawns, use sacrifice and cloak combo to kill it.
Phase 6 (2nd Mini MVP)
Instructions are quite similar to Phase 5, clear the monsters on the right wing and the second Mini MVP will spawn.
Equip shield with alice card, tao gunka with ghostring scroll + deviling garment, use sacrifice and cloak combo to kill it.
Phase 7 (Amdarais Boss)
A little heads up, this stage is quite difficult without experience.
Make sure to turn on your /effects, so you will know what skills the boss is casting.
Dont hit the boss when it has the Endure skill on, you can die from sacrifice.
You should equip garment with deviling card, shield with alice card
Have your solar swords / valk shield with alice cards ready for equip when the boss breaks them.
Make sure you are standing at the edge of the circle so you will have a higher chance of avoiding zombie bombs
Always be aware of your Shadow Scroll Buff as it can be dispelled. Make sure you rebuff when it gets dispelled.
After you have killed Amdarais, proceed to the treasure room.
This is an end game tier instance, you may not succeed on the first attempt but it does get easier with experience.
If you have any questions / suggestions, post them here or contact me in game. I'll reply most of them when i have time.
Hope this guide was helpful to you guys
Edit: Forgot to mention that you could make multiple Hero RGs on the same account (If you have 9 RGs you could farm OGH instance 9 times)
Equipments can be shared through storage, saves alot of money there. You should be able to farm 300-500 coag spells per run with bubblegum.
If you are a hardworking player, you should be able to farm a Khalitzburg Knight Card within 3 to 5 days. Happy farming everyone.
Edit #2:Info about Cloaking & Sacrifice combo. Casting cloak after sacrifice cancels the animation of sacrifice, allowing you to spam sacrifice faster.
