I like the ability in itself but I am not sure if it is well adapted to the present creature or if the term used are well chosen.
If with a little effort I might be able to see how a "Sigil of guidance" might "guide" other creatures to use another source of quanta for their ability. I still find hard to swallow that it would allow a steam machine to work without fire (in particular when an Orca is the guide), but let say it does. However, I cannot understand how a "Sigil of guidance" might (a) "guide" an inanimate object like an hourglass, a mindgate or a pulveriser (b) "misguide" the creatures/permanents of your opponent.
