Yeah but the thing you use to summon monsters with Ki are called "Seals of Invocation" so it's not a dumb mistake.
Nah, Superior Magic Recovery 3 gets you x 4 your base regen. and the Essential ability says it works exactly the same as that, so you could buy it three times for another +3 multiplier. capping out at x7.Not sure the Essential Ability (which can only be level 1) layers atop the CP gifts, but if it does then the whole thing maxes out at x4. For a whole LOT of expense, but some might find that worth it. A pure summoner doesn't need the stats so much, anyway, so they might convince their GM to allow them to dump two or three level-up CP into that.
Or at least that's how Siriel said it worked in his game. I guess you could read it differently in that it specifically uses the words "Double", "Triple", and "Quadruple". But why would you?
