Looks like it changed just before kunark was released.

***Patch Day***
The following is a list of changes that were implemented on the Live
EverQuest servers today:
*Spells*
- You will now receive a message when attempting to mesmerize a
creature that is immune to that type of spell.
- You can now right-click-and-hold on bard songs to determine what
instrument skill is used by the spell.
- Dyn's Dizzying Draught has had its casting time lowered
significantly.
- Corrected a bug in the Druid root + damage spells (Enveloping roots
series) that caused the spell's damage to have a chance of breaking the
spell. They work much better now.
- The Magicians Phantom Armor series now grants HP regeneration.
- The Druid spell, dance of the fireflies, has been changed from
"Outdoor only" to "Night only". It may now be cast in dungeons.
- Corrected a typographical error that allowed high level magicians to
inscribe the Malosi spell. It was not intended for magicians under
level 50.
