Why does Aisha Haadi need biological components for her spells?

Asking for the right biological components is the sign of honesty of the spellcaster you contacted as no effective spell may be cast without using material components related to the problem the spell should solve. Aisha Haadi, just as many other experienced spellcasters, needs some components from you in addition to everything else she needs to complete the ritual and create the talisman. Without components, no spell can be even remotely as effective as it is when they are used.
