What does 'Permeated tissues' Even mean? (Patreon)

So I wasn't even sure myself what this would do for Mason. I'm dabbling with a handful of ideas, and was wondering what you guys thought was cool.regardless of which one we pick, his skin is going to take on a faint mother-of-pearl look.#1 Large bonus to physical power. Since resistance is a multiplier of your base toughness, this effect will raise his base toughness, making him naturally inhumanly tough/strong. This option is kind of basic, but reliable.#2 Hollow man. Similar to how the pearls work, his inner organs are going to continuously shrink, being tucked away in extradimensional space, until eventually he is completely hollow, and very difficult to kill.#3 shield-HP. Mason's physical body becomes more shield than flesh, becomes much more durable, and can be repaired simply by gaining shield power.#4 Magical conduit: Mason's physical form has become more Charge-conducive, making his spells more powerful. Basically, his body is turning into a potent magical catalyst, a bit like unicorn horn. Will NOT make him more durable.Of course, suggestions welcome below if they're better than mine.
