Owl Adviser 1.0.3
Owl Adviser will show you on screen a little icon of the recommended next spell in a Moonkin rotation. The icon will disapear unless you are in combat and facing an hostile target.
It supports:

• NG clairvoyance -enabled by default
• Innervating yourself as early as you can and it's worth casting -enabled by default
• Force of Nature CD check
• Starfall CD check

It is ready to use when you download it, but you can configure:

• Icon's size and position
• Icon's alpha

How does it work?
The addon distinguishes 5 segments in a moonkin rotation, and shows the icon of the spell with higher priority in that segment and that won't be on CD when you end your current action (casting or GCD) . If it's Innervate, will obviously check player's mana.
The segments are:

1. Solar Eclipse
2. Lunar Eclipse
3. Solar Eclipse CD
4. Lunar Eclipse CD
5. No Eclipse

And the spells supported are :

• Faerie Fire
• Insec Swarm
• Moonfire
• Starfire
• Wrath
• Innervate
• Starfall
• Force of Nature

Each spell's priority in each segment can be changed ingame by slash commands, as well is Innervate's mana return (If you wanto to wait a little longer).
