How do I get my Guildmaster to let me practice Dispel?

I typed "practice dispel" and practiced dispel evil

I typed "practice 'dispel good' and practiced dispel good

I typed "practice 'dispel' and got huh?

what exactly do I need to type to practice Dispel (not dispel good nor dispel evil)?

thanks.


On a related note,

if a shaman is not empowered, does he/she have access to the shaman paths or does that come only with empowerment?

I've prayed at the shrine each of the last 4 days (sent a note on day 1), how long should I wait before I email?
