>invoke staff You lift your staff toward the sky and will the mana streams to bend into it. Roundtime: 20 sec.

@ 10 seconds: Your staff steadily brightens, until it burns like a glowing white torch! You find it too difficult to direct the flow of power you've conjured up, resulting in your ritual doing nothing more than jangling the mana streams.

@ 14 seconds: Your staff fades over the course of a few seconds, returning to normal.

this makes it unusable for the spell.
