The caster can curse any rune during its creation so that the magical aura it gives off is deceptive to hide the true spells and effects used to create it. During the rune creation, the caster may choose one alternate and applicable spell for the rune to appear as. The rune itself will resemble the rune of the chosen alternate spell and any Knowledge Arcana check that is lower than the true DC of the Spell will seem to be that of the alternate spell. The amount of MC required to do this is an additional half of the total amount of MC used to create the rune.
