Saiphyl Order monasteries dot the canopy cities and spun burrows of Tel'Nir, the reclamation-era homeland of the Veratic Elves. Saiphyl monks are taught a form of bodily control that inhibits the ability for magic to interact with them. This technique is known as the Sa'eai Saipha (from the elven prefix Sa indicating "from the self" and the word Ea meaning "permission," with Saipha being an elven term best translated as "a death of magic in a person, location, or object," thus Sa'eai Saipha indicates the practice of allowing your body to reject magic.) As a Saiphyl monk hones this art, they sacrifice their ability to cast spells or use magical items to improve their resistance to the arcane, disrupt magic with their bodies by temporarily extending the energetic field their body creates into their strikes,  terminate or redirect magical attacks, and eventually shut down unwanted spells cast anywhere near them as their physiology rejects any immaterial influence.

Arcane Resistance

Beginning at 3rd level when choosing this tradition, you dedicate yourself to rejecting magical influence on your body. You can't use magical items of common or uncommon rarity, but receive advantage on all saving throws versus magical effects. Attempts to use a magical item from which you are barred immediately fail.

Each time you gain a monastic tradition feature granted by this class, the rarity level of magical items you cannot use increases (losing access to Rare at 6th level, Very Rare at 11th, and Legendary at 17th.)

Dispelling Strike

At 6th level, when you hit a target with an attack granted by your Flurry of Blows feature, you can spend an additional ki point to create an effect functionally identical to Dispel Magic, except that it is not a spell and thus cannot be counterspelled or detected as magic. The effective "spell level" for your Dispelling Strike is equal to your proficiency bonus, and the relevant ability is your Wisdom. When you use Dispelling Strike, you target one creature, object, or magical effect. Any spell effect on the target is cancelled if it is of a level lower than or equal to your proficiency bonus. If it is of a higher level, you must make a dispelling check with your wisdom modifier as per Dispel Magic. In addition, by targeting a specific magical item that couldn't otherwise be dispelled, you can render it magically inert and non-functional for a number of rounds equal to a roll of your martial arts die.

Deflect Spells

Starting at 11th level, your body has become so resistant to magic that you can deflect ranged spell attacks. You can use your reaction to deflect or reflect the spell when you are hit by a ranged spell attack. When you do so, the damage you take from the attack is reduced by 1d10 + your Wisdom modifier + your monk level + your proficiency bonus. If the attack does not deal damage, you instead roll as if you were making a dispelling check with your Dispelling Strike.

If you reduce the damage to 0 or successfully counter the effect with a dispelling check, you can spend a ki point to hurl the spell effect at another target as part of the same reaction. You make a ranged attack roll (range equal to the original spell range) with your Wisdom bonus. You are considered proficient with this attack, and the spell is considered a monk weapon. If the attack hits, the spell effect takes place as normal for the spell.

Antimagic Presence

Upon reaching 17th level, you’ve molded your soul and body into the perfect shield against magic. As a reaction, you can spend 3 ki points to create an effect identical to Counterspell with the exception that it is not a magical effect and thus cannot, itself, be counterspelled or detected as magic. This form of Counterspell is cast at 6th level, with Wisdom as your "spellcasting" modifier. You can choose spend up to 3 additional ki points after you use this ability but before it is resolved if you must make an ability check as part of the spell, with each additional point spent granting you a +2 bonus on the ability check.
