Invisibility question.

[moonkin]

hello, Im still new to the game but I need something answered if someone doesn't mind I have and Eldar army, and I have Eldrad choosing telepathy so I can maybe get Invisibility. So my question is how long does Invisibility last? once a turn? all game? And if could someone please explain why? Cause almost all spells I have read will say if it only till end of turn or end of next turn, and Invisibility doesn't say that at all. Most the spells I see that don't say last till end of game. Thanks in advance for your answers and feedback.

Invisibility is a Blessing. Blessings last one game turn. See the BRB section on psychic powers.
