I really like the spell, it is one I cast before I start to hunt. With a 40 mana prep I get 4-6 spits, over a 40 rosian period.

You sense the warmth of the Dragon's Breath spell upon, which should last around forty-four roisaen or until you use it up as flaming spittle.

I am 78 circle, and pretty high magic skills
Primary Magic: 471 14% thoughtful Harness Ability: 489 99% muddled
Power Perceive: 360 42% learning Magical Devices: 461 93% very muddled
Targeted Magic: 326 55% clear

I believe Primary magic and some stats affect the number of spits ya get, and duration.
When I first got the spell some where around 50th circle I typically only got 3 spits.

The spell does not train target very well when compared to CL or GZ, and I do not think it is as accurate as a fully targeted spell.

The fact that it can be used while another spell is being prepped is a big plus. It also is very effective for picking off excess critters while training Multi.

Overall I like the spell, it is not one I would want to get rid of.
Hope that helps
