- As a level 99 Rune Fencer, speak to Gaddiux at (J-10) in Western Adoulin to receive a Trial Blade.
- Equip the Trial Blade and perform weapon skills with it to obtain Weapon Skill Points.
- 300 Weapon Skill Points are needed.
- Trust: Ayame uses weapon skills that elementally coordinate with the weapon skill last used by a player, functioning as a skillchain initiator. She is extremely convenient for quests that involve performing skillchains.  If you use Resolution, Trust: Ayame begins using Tachi: Kasha every time both you and Ayame have at least 1000 TP, allowing you to perform frequent Light (Skillchain)s for maximum WS points.
- If you choose this option, be sure to pick targets of reasonable strength. Kamihr Drifts is a good option.
- Once you have acquired enough Weapon Skill points, you will see Dimidiation available under your list of weapon skills, but only while your Trial Blade is equipped. There is no message in the chat log informing you of this; it simply appears in the list.
- Trade your unlocked Trial Blade back to Gaddiux to obtain 300 bayld and fully unlock Dimidiation for use with any Great Sword as Rune Fencer.
