Tyrant Sword of Forced Victor
~The holy sword of the Pendragon lineage but otherwise better known as Caliburn, it is identical to the sword once wielded by Arturia but "One Step Older". The holy sword wielded by Berserker before being placed in the stone of appointment at the time of his death. Originally a sword for the sake of selecting the king. Its "Anti-Unit" classification does not refer to the enemy, but instead point to the one who shall have ownership over it from now on. When the owner turns into a proper, perfected king its power will become appropriate for a holy sword, however as Berserker has been summoned in his disgraced self unworthy of being called a King, it's rank is locked in its current position. Although inherently inferior to Excalibur, this holy sword also converts the magic energy of the owner into heat value, releasing it as particles of light.
It is derived from swords with similar legends, Gram, "the sword of supremacy in the tree" from Northern Europe as itself was the model for it, including Merodach the original model of the "legends of swords of selection in the various lands of the world", and "the foundation of the sacred right to select the king" and as if it were to face them, it would lose due to being a newer incarnation.
It can be given freely to others unlike many Noble Phantasms but if it is wielded by a "True King", its power will increase to 'A+' Rank.
Flames of Dragon Gorlassar
The primary Noble Phantasm of Uther as a Berserker. The crystallisation of the "Red Comet" Merlin witnessed in the sky that prophesied Uther's reign. ‘A shining light to illuminate the darkness, however it will burn up quickly and destroy everything nearby when it crashes.’
Passively, it allows for superior mana generation to prevent this Berserker from burning out but when activated, it allows Uther to shroud himself in a veil of magical energy in the size and shape of a dragon. Although he cannot manifest this state for long and does not become an actual member of the dragonkind but rather a "True Imperfection" that can only exist for a a maximum of ten turns. However in this state his speed and offensive power increases and allows him access to the breath weapon that dragons hold.
It should be noted that as a result he possesses a weakness to "Dragon Slayers" in this state.
