Apparently, someone on /tg/ designed a sorcerous initiation that would allow a loophole for mortal martial artists... and also probably serve as THE most common initiation for Sidereal Exalted.
Enlightenment of the Imperfect Lotus
You have honed your mind and soul in distant monasteries and righteous battles, learning your own true nature in the process. Through these meditations and katas, you have grown aware of the chi that flows in and out of your body with each breath, and how to harness it. Through study of the martial arts of the Imperfect Lotus, you have grown to understand the flow of the world's energy, how to harness it, and even how to direct it back into yourself, a true master of the martial arts. (Note: This initiation does not require any investment in actual Martial Arts Abilities, but most of its Shaping Rituals and bonus Merits benefit from such investment.)
Shaping Rituals
• The sorcerer centers herself through her martial arts, motions and katas designed to guide the flow of the world's essence around and through her. The sorcerer may make spend a point of willpower and make a martial arts roll (Perception + Martial Arts) gaining one Sorcerous Mote per success on the roll as the martial artist flows through slow, meditative katas, breathing in and out to gather their chi as a miscellaneous action. Sorcerous motes gathered in this manner remain until the sorcerer next sleeps, loses consciousness, or otherwise takes an extended rest. Activating this ritual again replaces the Sorcerous Motes already acquired with previous activations rather than adding to them.
• The sorcerer has refined his soul through battle like a blade tempered in flames. To that end, the sorcerer is now empowered when she fights against foes in combat. Whenever a sorcerer strikes a Withering attack against a foe in combat, she may channel any amount of Initiative she would normally gain from such a strike into half as many Sorcerous Motes instead. Once per battle, when she lands any blow with or supplemented by a Control Spell against a foe Decisive or Withering she gains Essence Sorcerous Motes on top of any other that the ritual would grant. Sorcerous Motes gained through this ritual fade at a battle's end, in the same moment that its combatants leave Initiative.
• The sorcerer gains one Sorcerous Mote every time they successfully dodge, parry, or soak an entire attack in battle. If the attack was successfully defended against through the help of a Control Spell which in some way improves the sorcerer's ability to dodge, parry, or soak, then she instead gains two Sorcerous Motes. Sorcerous Motes gained through this ritual fade at a battle's end, in the same moment that its combatants leave Initiative. (Example: John of the Mountain is a battlesorcerer with Invulnerable Skin of Bronze as his Control Spell. When attacked by a bandit while transformed by the spell, a sword blow glances harmlessly off of his body. Normally, he would gain one Sorcerous Mote from this, but because it is his Control Spell, he gains two.)
Other Benefits
• Fist of the Lotus (Merit •••••): The sorcerer may learn Martial Arts charms for which she meets all prerequisites as if they were sorcerous spells, allowing them to be activated with Sorcerous Motes instead of personal or peripheral motes as normal. Normal Martial Arts charms gain this benefit with an additional cost of 1xp. (Note: This expressly allows mortal martial artists to learn Essence 1 Martial Arts charms for which they otherwise qualify as sorcerous spells.)
• Signature Technique (Merit ••): The sorcerer may select a Martial Arts charm made into a spell through Fist of the Lotus as a Control Spell. If taken after Initiating, it allows the Martial Artist to swap a Sorcerous Control Spell for a Martial Arts one. Once taken, this effect is onetime and permanent. (Example: Master Shin Qo, a mortal master of Crane Style, chose the spell Obsidian Butterflies as his control spell upon initiating. Later, after gaining Empowering Justice Redirection as a spell through Fist of the Lotus, he takes Signature Technique to replace Obsidian Butterflies with Empowering Justice Redirection as his Control Spell. Once this purchase is made, it is permanent.)
