The Symbolist is a unique class, that uses rune like symbols to apply effects all over the place. How does it work you ask? If only this very video explained it all :D
To help out on the “borne by themselves” thing, the book is using borne in the meaning of ‘carried’. ‘Applied to’ would probably be a better phrasing. Also, to make a case for the symbol of creation, it works best in a party that either relies on item healing (remedies and elixirs both cost 3 IP) or that has a Tinkerer. Several of the Tinkerer’s abilities cost more than 2 IP, so this symbol lets them use their abilities more. An alchemist would normally spend 4 IP on their 3d20 potions, so this makes those half price. Honestly I think alchemy Tinkerers should take a level in this class specifically for this symbol because I believe Deep Pockets would apply. Spend 1 IP out of combat to apply the symbol to themselves, then they use it to produce a 4d20 potion. A 5 IP item for 1 IP, once EVERY conflict? That’s crazy good.
