The Mayhemic way of the Biolo by Meep

Still WIP

Introduction

Hello, I am Meep, and I've been playing MuhRO for months now. I started as a Biolo and still am one. I'm not very good at anything math-related, so if you have any questions about math, I'm not the guy for that—lmao. I'm making this guide to help beginners navigate from the early game to the endgame. This guide will not cover all gear options, especially those I deem wasteful, as acquiring such gear wouldn’t significantly improve farming efficiency in the areas I'll be mentioning. This guide focuses on Biolo, starting with the Mayhemic Thorns build. I may add more builds in the future (or when Time Gap comes).

Why play Biolo?

Play what ever you think is fun. You may or may not like Biolo gameplay so I would list down some pros and cons

So why play Biolo?

As a Merchant class, Biolo grants us many quality-of-life skills like Enlarge Weight Limit.
Has free Guyak from Cart Boost and a massive weight capacity, making farming easier and more efficient.
Can create potions and food that provide stat buffs.
Generally easy to gear, and its equipment can be shared with other crit-build jobs.
It is a good farmer, even in the latest dungeons.
Has a homunculus that provides buffs and helps with tanking.
One of the best instances farmers.

So why not play Biolo?

The damage of Biolo cannot compete with other magic-class jobs or other physical-class jobs in the late game.
Some skills require a consumable to be used.
Not magic
Magic classes dominates the end game dungeons.

Skills

Relevant Skills

Mayhemic Thorns: The skill that you would be using a lot. It is a 9x9 AoE range skill that the damage can be boosted by Creeper and Hell Tree. Every skill cast recovers 2 AP so make sure to use it (or else you wont do damage)!
Research Report: Makes your Mayhemic Thorns damage bigger. Buffs Acidified damage against formless and plants. Try to have this active at all times.
Hell Tree: Buffs your range damage and against formless. I don't usually use this unless I'm killing MvPs or for High end dungeons.
Blood Sucker: Gives you a chance to absorb the damage you dealt as HP. Basically like a Succubus Egg (9055)
Cart Boost: The best movement skill we got. This basically has the same speed as Guyak Pudding (12710)
Call Homunculus: Calls out your Homunculus. It can take aggro from mobs whenever you TP for efficient farming. This consumes Seed of Life (7140) and only last for 30 minutes unless it dies which in that case you can use Resurrect Homunculus to call it for free.

Situational Skills

Full Shadow Protection: Protects shadow equipment of the target from being stripped or destroyed. Useful for certain instances
The Whole Protection: Protects weapons and equipment of the caster and nearby party members from being stripped or destroyed. Only useful for party plays.
Full Chemical Protection: Protects your gears or party member's gears from being destroyed.
Acidified Zone Fire or any Acidified Skills: For monsters that requires multi-hitting damage. Can also be used to regain fast AP.
Crazy Weed: Can remove Spider Webs in Depth 2 and reveal hidden enemies.

Stats and Traits

Stats

STR: This is multiplied with your Weapon ATK increasing your damage.
AGI: Increases your attack speed but we don't really need that much attack speed unless you're in a high density map.
VIT: Gives us defensives stats and having it at 92(?) would give us stun immunity
INT: Provides the second-highest reduction in Variable casting time. Useful for faster cast times.
DEX: Primary stats for range damages. Increases our hit chance and the highest reduction in Variable Casting Time.
LUK: This scales with C.rate and gives us CRIT for a higher chance to do critical damage. Increase this if you need more Crit so you can try and hit 100.

Traits

POW: Has the biggest boost towards our damage. Have this high.
STA: Provides Res.
WIS: Provides MRes.
CON: Provides P.Atk but the damage is underwhelming and you can get it from your gears (also provides flee).
CRT: Our main way of getting C.rate. I usually have this maxed.

Sample Stats Allocation
Stats	Allocation	Traits	Allocation
STR	110	POW	110
AGI	3	STA	0
VIT	90	WIS	32
INT	100	CON	40
DEX	130	CRT	110
LUK	106

(Note that you can go 0 on STA and WIS and put all on CON)

Gear Progression

This is the beginning of your journey. Take it slow or fast. Just have fun and enjoy the journey! Also, you shouldn't rush to the late game, as your farming efficiency improves with the new gear you acquire, making it much easier to earn Zeny.
First we must learn about Mayhemic Thorns. It has a 0.7s Cooldown with 0.5s Fixed Cast time so it can be slow but with the help of gears and stats you can lower those numbers down. Just using Grace Attack Boots [1] (470020) reduces your FCT by 0.5s. Utilize the free buffs that you can get in Eden Group such as Almighty (12883) for faster casting.

Beginner

Gears

Not much to say here other than to use equipment from either Eden Group or Episode 17.1. You do not need to worry about getting cards here. Try to use this until you can get the gears in the next section.

Slot	Gear	Where to get
UpperHeadgear	Advanced Paradise Luxury Cap (400139)	Eden
MidHeadgear	Sealed Chain [1] (410094)	Nilfheim 2
LowerHeadgear	Bondage Necklace (420076)	Nilfheim 2
Armor	Grace Cart Cannon Suit [1] (450100)	Ep17.1
Weapon	Paradise Genetic Mace (590028)	Eden
Shield	-----
Garment	Grace Attack Manteau [1] (480018)	Ep17.1
Shoes	Grace Attack Boots [1] (470020)	Ep17.1
Accessories	Grace Attack Ring [1] (490019) Advanced Paradise Ring (490126)	Ep17.1 Eden

Where to farm Zeny

These are some good farming spots that I know and have proven to be effective. A quick tip: use @storeall and @getall for storage, and always use a [Bound] Bubble Gum (12264) . Bring [Bound] Kafra Card (23177) , Almighty (12883) , and Small Mana Potion (23203) , which you can buy from the Eden vending machine for quality-of-life improvements.

Location	Note
Gefenia	A really good way for beginners to farm raw Zeny. Just make sure to bring [Bound] Kafra Card (23177) and an empty storage for more efficient farming sessions.
Istana	You farm Elunium (985) and Rough Oridecon (756) here which will overweight you so bring [Bound] Kafra Card (23177) . You can turn Rough Oridecon (756) into Oridecon (984) at @go 50. Everything will be either vended or be used by you.

Early Game

Now that you have gained some zeny, you can now move to the early game gears. These gears are pretty good and would increase your damage. Note: Try reading Midgame and Late game stuff first and check if you can skip some of the gears.

Some of the Eden and Grace gears are still good such as the Grace Attack Boots [1] (470020) as it gives 0.5 Fixed Cast Time that Mayhemic Thorns needs. Replacing Grace Attack Boots [1] (470020) with Illusion Sprint Shoes [1] (470066) requires you to either get +11 for both Illusion Sprint Shoes [1] (470066) and Illusion Sprint Mail [1] (450182) to get the FCT or use Genetic Stone (Low) (1000671) with Sword Training at level 5. For Shadow gears, just use the Advanced Paradise Shadow Gears that you get from Eden.

Gears

UpperHeadgear	+10~+11 Temporal Circlet (Genetic) [1] (19477)	Can wait till Mid game for enchants
MidHeadgear	Sealed Chain [1] (410094)		Combo with Bondage Necklace (420076)

You can mix them together if you cant find the perfect one.
Weapon	+9 Glacier Mace (590038)	Glacier Flower Spell (Mayhemic Thorns) (311448) or Glacier Flower Spell (Physical-Element) (311352) / Glacier Flower Spell (Physical-Size) (311350) / Glacier Flower Spell (Physical-Race) (311348) / Glacier Flower Spell (CRI) (311344)	This is your biggest damage boost and quite cheap to get, just try checking vendors or shouting in #trade.

Rune of Dexterity Lv2 (29004) for faster cast time (I prefer this) or Rune of Strength Lv2 (4995) for more damage. You can mix them together if you cant find the perfect one.
Accessories	Sinful Ruby Ring [1] (490044) Sinful Ruby Necklace [1] (490045)	Anger Lv5 (310201) /Any	You honestly do not need to enchant these but if you can then try.

Good Farming Places

Dungeons that you should be able to gain zeny from with the current early game gears including the ones from beginner section. Always keep Shadowdecon Ore (25728) , Shadowdecon (25729) , Zelunium Ore (25730) , Zelunium (25731) , and Etel Dust (1000322) when farming as they can be sold or used for crafting.
Also see Increase item drop gears guide to increase your zeny farming rate. Poring Family Balloons, Poring Sunglasses (19117) , and Angel Poring Boots [1] (22101) is a good start.

Location	Note
Rudus 4	Good raw zeny but keep Cor Core Booster [1] (410092) , CD in Mouth (420003) , Battle Processor [1] (410017) , and Magical Booster [1] (19241) for vending.
Thanatos F9 - F12	Auto-loot all and bring at F12 unless you can manage the slow de-buff from mobs. Keep Fragment of Agony (7436) , Fragment of Misery (7437) , Fragment of Hatred (7438) , and Fragment of Despair (7439) for daily hunts for free Forgotten Heirloom (50001) which can drop Blacksmith's Blessing (6635) . The other fragments (ex: Fragment of Resentment (1000245) ) are also for Piece of Sin (1000257) and Fragment of Good Will (1000263) which can be sold to other players or used by you.
Niflheim 1	Raw zeny with Shadowdecon Ore (25728) , Shadowdecon (25729) , Zelunium Ore (25730) , Zelunium (25731) , and Etel Dust (1000322) drops. Gan Ceann Card (300240) for some zeny in vending.
Oz Dungeon 2	Drops Amethyst Fragment (1000405) which can be sold in vending. Good money to be honest.
Old Glast Heim Normal/Hard	Can auto-loot all or just auto-loot Coagulated Spell (6608) , Contaminated Magic (6755) , Elunium (985) , and Temporal Crystal (6607) for vending. 10 minutes per run after unlocking fast mode. Do not forget to talk to the NPCs after killing each boss as they give rewards and unlocks the secret room.
Gefenia Doping	Best way to earn money if you can do it with the buffs that is listed by LuckNut. Does not really need to change your gears but if you can't do it with buffs then try swapping some gears. You can also do this at Thanatos F8.

Mid Game

This section will talk about gears that you can temporary use and also gears that you would use for end game. These can be expensive to buy or craft so buckle up! Some early game gears are still used but enchanted.
