Crystal-Matrixing, a Magical Skill. Campaign has Energy-Crystal powered devices, as well as the option for combining different types to get PP for spells.
For example, someone casting Obscuring Mist could use a Water or Air Crystal.
Say that Kingpin Lar-Lar (Actual character from my last campaign) was casting his spell, and he needs a doozy. Chased by rival pirates, he needs to obscure just which estuary cove he has hidden his sloop within. Spell:8PP,Deep Mist+3, Radius_30', +6PP,Range +100', +2 PP,
Duration 1 minute/rank, +8 PP, for a total of 27 PP.
Now, Kingpin has been fighting hard, and only has 22 PP left, but he happens to have a bag of Air and Water Crystals that he has been saving for this sort of emergency. He has 20 PP in Water and 10PP in Air crystals
He has no time, as they are bearing down on him, so he works hastily (-30), In addition, he is trying to combine more than one type of energy (-20). At least they are stabilized (Worked) Crystals, as opposed to some that he just found...
His bonus with C-M is +85, he rolls a 43, -40 in mods (Above, for a total of 88=80% on the MM table. Of the 30 Points stored in the crystals, he successfully (the rest disperse) tapped 24 PP...leaving only 3 needed from his natural reserve. Let's just hope that those rivals don't have any goggles loaded with the appropriate Crystals to see through his Mist...
