Assisted Breathing Mask

[Ion Mage]

A more intuitive way of doing this I think would be to make it possible to open the tank valve while the mask is in your hand (not just your face) and then, as you can guess, placing the mask in your hand and then clicking on the intended recipient.

The less intuitive one you edited into the OP is indeed unintuitive... I probably would never have discovered it if you hadn't just mentioned it here.
