Obojima Tales from the tall Grass - Origami Mage (Wizard Subclass)

At level 2, you unlock the ability to summon an Origami familiar. This familiar levels with the character's Wizard level. When you reach Wizard levels 6, 9, and 12, the familiar will also be that level. The familiar can become invisible, much like Shovel can. Each familiar has a spell called "Last Resort", which blinds the target but also simultaneously damages the familiar. It's a concentration spell, so the familiar taking damage from the spell may cause them to break concentration.

You also unlock the ability to create origami figures and attach them to other characters. These figures are not summons, but function as buffs instead. You can create a number of figures equal to your proficiency bonus.

At level 6, your origami familiar gains some ability score improvements and the ability to cast spells. It can only cast spells with a range of touch, and it has its own spell slots.  The familiar also gains feats with every level they gain (War Caster at level 6, Mage Slayer at level 9, and Sentinel at level 12)

At level 10, you gain the ability to create origami servants. These servants can use See Invisibility as a cantrip. When you cast the spell, a number of servants equal to half your Wizard level (rounded down) will spawn. They only have 1 hit point each and 10 AC. They start invisible and can turn themselves invisible should they lose the condition.
