There are things that need to be done. Need to be done even if no one's around to do them. Well, no one's around!

Patch. That. [i]Hole[/i]! The air hole, not the blood holes, though that needs to be done too. Respiration is the key to mana flow, it's the link between the self and the natural world. The deeper, slower and quieter the breaths the more the spirit is able to reach harmony with that flow. You can't intake mana while yapping, and snoring is even worse - it's the vocal chords scratching incoherent spell-notes into the mana flow, burning energy as quickly as it arrives. Chronic snoring can ruin a career as a magician as surely as it can get you kicked out of bed. And so a gentle little adhesive is applied, bringing the lips together and forcing that flow through the nose instead. As important as any bandage.

But we've got those too! Soaked in slow release relief spells, brightly coloured with rainbow glyphs and unicorn runes. The rainbow is important - you can be as contaminated by fiery red making wounds itchy and hot as corrupting black invites in decay. A constant oscillation of mana types is important to give the body time to work its own healing and reassert its own identity. Burn out the black with red, quench the red with blue, drink the blue with green and ignite the red before the fungus starts growing in. It's not so much about balance as it is about sprinting past consequences. 

But as for the deeper stuff? The invisible problems, the wear on the bones, the stress that becomes insomnia that becomes eye twitching madness that becomes eczema? For the things that have gone so deep that they've stopped being identified as debuffs and look like bad stat rolls on level up?

Well...

No one can cast HEAL, right? Eclair said it herself. It's impossible.

So no one does.
