Im going to post a build here. Hafta go out first. Leaving a msg so I wont forget.
Im not sure what equipment you have and your capacity to purchase the equipment I will mention, so I will just post the low tier equipment up to the high tier equipment that you can get. LOW TIER - Low Budget Headgear: Upper - Flying Angel(ASPD 3% - cost 5 TC), Hermose Cap[Vanberk] - 5 TC but it will reduce your ATK), Wikebine Cat Ears(Crit DMG 10% - 5 TC I think, not sure if I spelt it correctly, can be obtained thru quest), Morriganes Helm (the whole set is not advisable bec the other items are expensive) Middle - Any slotted mid either STR or AGI stats (Vanberk), Filir Wings(Adds ASPD 2% I think - 5TC), Robo Eyes Lower - 'ol reliable Pirate Dagger or any ATK increasing lower headgear Armor - ASPD / AGI / STR enchanted armor preferably Odins Blessing (For the Falcon Muff - Fricco Shoes combo) // Thief's Clothes. Armor either carded with the following - Porcellio for added ATK, Venatu which switches every 18 AGI, you gain 1 LUK, Alicel for added FLEE, or Ancient Mimic for every 18 LUK you gain 1 AGI Garment - Falcon Muffler, Any cheap slotted Garment, Crest of Rider (assuming if hes a SinX) - carded with the following: Whisper Card for additional FLEE, Aliot for additional HP and STR 2, Bapho Jr. for AGI 3 and Crit Rate 1%, Giant Whisper Card for FLEE 10 and base stat bonuses, Hyegun for Flee +15 and CRIT rate 1, Wanderer Card FLEE +20 and for the Assassin Card set Footgear - Fricco Shoes, Crystal Pumps(LUK 5), Black Leather Boots(Assuming hes a SinX - for the Crest Rider Combo), Shackles (For Bloody Shackle Ball Combo / Rental), Any cheap slotted Footgear carded with the following: Chonchon Card (AGI 1 FLEE rate 2), Wild Rose Card Accessories - Bloody Shackle Ball / Rental, Rental Vesper Cores 3 or 4 (Can be used by non-trans), Critical Ring / Rental, Thief Ring(If SinX), Goddes of Fortunes Cursed Brooch, Rosary. If you got a slotted accessory you can put the following cards: Shinobi Card, Kobold Card, Mantis Card, Yoyo Card Weapon - Rental Infiltrator / Infiltrator, Rental Jamadhar, Rental Speed Katar, the elemental Katars with 3 slots, over-upped Jur or better Specialty Jur carded with the following: Soldier Skeleton Card, Mobster Card, Sedora Card, The Paper Card. You can mix and match them depending on your taste or preferred build. Also if you cant afford a Doppelganger Card, Cecil Damon Card boost ASPD by 5% but sacrificing HIT, so thats one alternative Middle Tier - Headgear: Upper - Lord Kaho Horns Middle - Any slotted mid headgear with AGI or STR stat carded with Gryphon Card Lower - Any ATK increasing lower headgear Armor - Any STR, AGI, ASPD enchanted armor, if SinX can go for Dragon Vest for the combo Garment - Overupped Hood till +9 carded with Chung E card - with this it gives you a great boost in CRIT rate Footgear - Bunny Slippers with Mysteltainn Card Accessories - Celebration Ring x2 Weapon - Same card combo with Specialty Jur but, adding a Doppelganger card or 2 to reach high ASPD FILTHY RISHHHH TIER -
Upper - Valkyrie Helm with Gryphon Card Middle - Any FANCY slotted middle headgear with AGI or STR stats with Gryphon Card Lower - Any ATK increasing gear Armor - All slotted Elemental Armors with AGI STR or ASPD enchant carded with any necessary MVP cards, or a +7 stat enchanted Dragon Vest with the same manner of cards Garment - can go with +9 Hood with Chung E Card but rather get a +9 Dragon Manteau for the Dvest Combo, +9 Proxy, +9 Diablos Manteau Footgear - Sleipnir with Mysteltainn Card Accessories - Brisingamen x2 both with Ifrit Cards Weapon - Twin Fang with all the necessary MVP cards. Better if you can carry 2
Hope this helps.
