Height Modifier
From SpiralKnights
A Knight can permanently change height through the use of Height Modifiers, which are destroyed afterwards. This is purely a visual change and does not affect gameplay.
Normal, Short, and Tall Height Modifiers can be purchased from Vatel for 50,000 crowns. Short, Tall, Extra Short, and Extra Tall Height Modifiers may be obtained from Mirrored Lockboxes at a fair chance, or from Iron Lockboxes at a very small chance.
