Orkrista has several different forms, but frequently appears as a white cap that Zeno wears. During combat, it can transform into a staff which can split into two and connected by a chain like nunchaku.
In many ways, Orkrista is similar to King's sacred treasure, Chastiefol. Some of its different forms include:
Cap: When not in battle, the rod remains in the form of a cap.
Form One, Rod: Zeno frequently utilizes this form, which is a rather short rod, and can split into a two-section staff. Zeno uses this form of his weapon for short-to-mid range attacks, unlike King, who uses his levitation abilities to use his weapon for mid-to-long range attacks.
Form Two, Defender「保護者 (ディフェンダー), Hogo-sha (Difendā)」: Orkrista takes on the form of a large, stuffed, and white-coloured dragon. While in this form, it can be controlled by Zeno to fight or immobilize enemies by wrapping around them. It bears a weakness against hot and fire attacks.
Form Three, Drowsiness「眠気 (ドロウジネス), Nemuka (Durōjinesu)」: This form of Orkrista looks similar to a tree-branch with a sharp, sturdy and pointed end. This form has the ability to put whoever it pierces to sleep, rendering them unmovable and practically in a state of eternal drowsiness.
Form Four, Catastrophe「壊滅 (カタストロフ), Kaimetsu (Katasutorofu)」:
Form Five, Shotgun「散弾銃 (ショットガン), Sandanjū (Shottogan)」:
Form Six, X-ray「透視 (エックスレイ), Tōshi (Ekkusurei)」: This form of Orkrista allows the user to literally scan a particular area, telling him the exact location and certain peculiar traits of hidden people, objects, etc. in the area.
Form Seven, Illumination「照明 (イルミネーション), Shōmei (Iruminēshon)」: Creates a small light sphere enclosed within a cubicle to brighten up dark area around the user.
Form Eight, Waterfall「滝 (ウォーターフォール), Taki (Wōtāfōru)」:
Final Form, True Royal Rod Orkrista「真・王棒 オークリスタ, Shin Ōbō Ōkurisuta」: The true form of Orkrista.
