As the level go higher, player had to make use of the Elemental System to their advantage. It start as early as Level 31 when they change class, as some of their skill had Elemental Attack or Defense. To kill Raid Boss effectively they had to put Chaos Jewel with Elemental Properties on Weapon and Armour. The effect is not so critical at low level but it became more and more essential as their level go higher.
Level 30 Grand Balrog had Fire Attack and Dark Defense, so it will be better to put Diamond for Light Attack on Weapon and Sapphire for Water Defense on Armour. Level 50 Grand Red Dragon had Fire Attack and Wind Defense, so it will be better to put Emerald for Earth Attack on Weapon and Sapphire for Water Defense on Armour. Wizard Terre Spear, Assassin Hide Step and Elementalist Hand of Earth will be effective against Grand Red Dragon.
Level 70 Grand Devilroad Kamira and Level 77 Erebus had Fire Attack and Defense, so it will be better to put Aquamarine for Water Attack on Weapon and Sapphire for Water Defense on Armour. Although Level 73 Barren Eise had Wind Attack and Earth Defense and Level 75 Blood Terrain had Light Attack and Wind Defense, they are much easier to kill as compare to Grand Devilroad Kamira and Erebus so it is more advisable to focus on Grand Devilroad Kamira and Erebus. But player can consider putting additional Turquoise for Earth Defense to counter against Barren Eise as it is also using Magical Attack.
Royal Knight Double Bash, Wizard Freeze Arrow, Elementalist Ice Spike 2 and Specialist Sonic Break will be effective against Grand Devilroad Kamira and Erebus. Highlander Cannon Spike 2, Wizard Flame Field, Ranger Flame Arrow, Elementalist Soul of Fire and Specialist Inferno Volt will be effective against Barren Eise. Wizard Terre Spear, Assassin Hide Step and Elementalist Hand of Earth will be effective against Blood Terrain.
Now they can focus on farming for Level 73 Blue Weapon at Temple of Forgetfulness, it will be advisable to put Black Pearl on the Weapon as Dark Element is strong against All Element except Light. It will be good for farming for Level 75 to 77 Blue Armour Set at Egeha, it would be advisable to put Garnet and Sapphire on Armour to Defense against the Earth Attack of Iludeterirun and Fire Attack of Arch Lich. Can also consider putting Turquoise too to Defense against the Wind Attack of Nivas, with this setup it can be use for other toons later for Grand Devilroad Kamira and Erebus too.
Next will be farming for Level 85 Blue Weapon and Level 85 to 87 Blue Armour Set at Lust Trum, it will be more simple as just had to put Emerald on Weapon for Earth Attack against the Sphinx Commander Wind Defense. As Darkmind Terrain had Light Defense, any Elements other than Dark will still be effective against it. The only issue is Anubis Spear Man is having Water Defense so Earth Attack will be weak against it, but compare the Boss the Elite will be much easier to kill even without the Elemental Advantage.
Emerald will also be effective against Grand Gold Dragon Wind Defense, as most player will be using this set for grinding in Egeha it will be useful if they had that advantage. It is also advisable to put Fluorite and Pumpkin on Armour to Defense against Darkmind Terrain Dark Attack and Anubis Spear Man Water Attack, as Anubis Occulist and Sphinx Commander is using Light Attack any Elements other Dark will be strong against it.
Most players will try to level up fast at Tomb of Theo right after Temple of Forgetfulness and choose to skip Egeha, so they would not need to have so many set of Weapon and Armour. As I am a farmer and I like to do drop hunting and raid boss hunting, this will just be use as a general guide for those who prefer to enjoy the game at a slower pace. Getting more Blue Weapon and Armour Set will also help other players as there is a serious lack of resources as the demand is always more than the supply.
Tomb of Theos will be a place to farm for Level 97 Blue Weapon and Level 95 to 97 Armour Set, some prefer to get Purple Weapon and Armour Set from Akan Temple Hard but Purple Gear cannot be change to other class. It would be simple for this setup as we only need to focus on Shadow Dragon, they are having Dark Attack and Fire Defense so just having Aquamarine on Weapon and Fluorite on Armour will be able to gain advantage over it.
Streiana is easy as most mobs does not have any Elemental Attack or Defense, the only mob with Elemental Attack and Defense as mentioned earlier is Shadow Dragon. This will be a place to farm for Level 109 Blue Weapon and Level 105 to 107 Blue Armour Set, you can get Level 100 to 115 Purple Gears in Extreme Cube but the same issues of unable to change class became a major turn off. It will be advisable to put Diamond for Light Attack on Weapon and Garnet and Sapphire on Armour for Fire and Water Defense, this is to gain advantage over Leviathan Earth Attack and Dark Defense and Hecate Fire Attack. The other concern is Bael Water Attack and Manzazuu Dark Attack so maybe can consider putting Pumpkin and Fluorite on Armour to Defense against that, but as we are not farming on them as there are other easier mobs to farm on we can avoid that.
Bloodymir will be a place for farming Level 121 Blue Weapon and Level 115 to 117 Blue Armour Set, it would be advisable to put Ruby for Fire Attack on Weapon and Sapphire and Pumpkin for Water and Wind Defense on Armour. This is for gaining advantage over Fluton Fire Attack and Earth Defense and Patriarch Botis Water Attack and Earth Defense, the remaining of the mobs does not have any Elemental Attack or Defense and Raging Spirit of Sorcerer is the popular mobs for fast leveling.
Floraim Cave is for farming Level 145 Blue Weapon and Level 135 to137 Armour Set, it is also a place for farming Skill Books. It would be advisable to put Ruby for Fire Attack on Weapon and Garnet, Turquoise, Pumpkin and Fluorite for Fire, Earth, Wind and Light Defense on Armour. The main reason for choosing Ruby for Fire Attack on Weapon instead of Black Pearl for Dark Attack which is effective against All Elements is because the one of popular Seeker is having Light Defense and Rawhead is having Earth Defense, so Black Pearl will not be effective against Seeker but Ruby will be effective against Rawhead. The Garnet for Fire Defense is mainly for the Raid Boss Skeleton General, as it is also having Light Defense Black Pearl would seem a bad choice for Weapon.
Mondsnihe would be for farming Level 157 Blue Weapon and Level 154 to 156 Blue Armour Set, does matter what Element is on Weapon as Hackboss Grokta is having Light Defense so as long as it is not Black Pearl should be ok. The main concern is to put Garnet for Fire Defense against Earth Attack of it. Level 154 to 157 Purple Gears can be found from Cotantoce of Ruin and Level 163 to 165 Purple Gears can be found from Heretic Drill Master Chief Toffse.
Ramslo Lab would be a place for farming Level 175 Blue Weapon and Armour Set, putting Aquamarine for Water Attack on Weapon and Fluorite for Light Defense on Armour will be effective against Black Tyrant Ramslo Phantom Dark Attack and Fire Defense. Level 170 to 173 Purple Gears can also be found at Tairan, but the one from Black Tyrant Ramslo Phantom are better. The Level 186 to 190 Purple Gears will be from Theos Darkness.
