"...Although it's a bit messy, it's not a big problem."
Aiwass thought for a moment and made a suggestion, "Still, prioritize finding the [Cunning Spell]. Cunning Spell can give you a second chance to remedy any spell or spell-like ability that does not cause damage when it fails."
In gaming terms, it meant that all non-damaging spell abilities could be re-rolled once upon failure.
"I think Master Yanis encourages you to find this trait because you have the 'Agile Singing Voice,' and there is a chance you may fail when singing complex Enchanted Tunes later on."
"From an expected value perspective, for instance, even if there's only a one in five chance of succeeding, your success rate jumps to over one-third with Cunning Spell; if it was originally one in three, it will become about half; if it was half, it turns into three-quarters."
