Fanmade Extension and Maximum Techniques (Jujutsu Kaisen Supplement)

Extension and Maximum Techniques

This is where suggesstions for non-official extension and maximum techniques you can gain using the Extension Techniques Variant Rule will be listed, so you may put any kind of extension or maximum technique for any Innate Technique. Most of these are not made by the original creator of the class, so don't expect for them to be constantly monitored or changed by them.

Explanation of Extension Techniques

Based on a Jujutsu Sorcerer’s Cursed Technique and abilities, they are capable of creating Extension Techniques which further the efficiency of this style of Jujutsu. A character can only have a total number of Extension Techniques equal to their Charisma modifier + their proficiency bonus. Extensions should deal more damage and cost more than their lapse counterparts, ranging from 2-10 cursed energy. Players can discuss with their DMs when creating an Extension Techniques to determine their features and how much cursed energy they should cost.

Aditionally, you may ask permission from your DM to add a new property to an already existing technique when you use Maximum Output on it. Examples of this are when using Maximum Output on Blue one is now able to move it around, and when using it on Flowing Red Scale it becomes Flowing Red Scale: Stack, which gives new benefits.

Explanation of Maximum Techniques

Additionally, you can create an Extension Technique that realizes the greatest potential of a Jujutsu Sorcerers’ derived Innate Technique known as a Maximum Technique. They are the most supreme art of any sorcerer who possesses a Cursed Technique outside domain expansions. You can only have one Maximum Technique at a time which is treated as five Extension Techniques for the purposes of determining your current limit for Extension Techniques . A Maximum technique should at minimum be a 10th level feature and deal 10 dices of damage. In case it deals less than said damage, you must compensate it by making a very strong effect such as paralizing your opponent. Maximum techniques cost at minimum 10 cursed energy, and at maximum 20. Reasonably, Maximum Techniques are extremely powerful and equally costly so discuss with your DM regarding what may be allowed in terms of a Maximum Technique creation based around your Cursed Technique.
