Echo Stabilisation

Through intense training you’ve managed to better ground the unrealised timelines from which your shade echoes. When manifesting your echo you may create a Stable Echo, its AC is equal to 14 + your proficiency bonus (or your own AC, if it is higher), it has resistance to all damage, and immunity to all conditions. The Stable Echo may perform object interactions but has no tangible weight. The Stable Echo may not be destroyed by damage, whenever it would take damage you instead take that amount (accounting for resistances). Finally, swapping with the Stable Echo does not require a bonus action and instead only 15ft of movement, this may still only be done once per turn.
