Invisibility vs Undead

From EQ Clerics Wiki

These spells hide you from most undead mobs. Some mobs CAN see through it, but most undead mobs will not. Unless you also have a regular invis active, non-undead mobs will also be able to see you normally.

It comes in both single target and group versions.

These buffs are level limited; you must be over a minimum level before you can receive the buff.

Also, like all invisibility spells, you must be in the target's group before you can cast it on someone else.

Some of these buffs can fade before their full duration. This is a random effect, so you need to be alert unless the spell is constant duration.
