Lesser Invocation
4th Level Spell

You can beguile a creature within 60'. They must
make a Will save or regard you as an ally. The
charm lasts for 1 day per caster level, but you can
only have one creature charmed in this way at any
time. If you charm another creature, the first
charm will be canceled.
