Magician's "Lesser Conjuration" line of pets+ more?
 

http://wiki.project1999.org/Magician#Pet_Information

"Spell: Lesser Conjuration: (Earth, Fire, Water, Air)
Level: 39
Pet Levels: 33"

Was using this spell at 41, and getting the odd light blue con pet. I'm not sure the level range this implies, but this pet line should be a static level 33 according to wiki"
Not sure if the next pet line still has variance (I'm not a high enough level to test the "Conjuring" line , or it's only a goof on this line), or if it's working as intended (and the wiki is misinformed).

Dont think any pets are static levels. Could be wiki misinfo.if u think pets under expected level range thats another issue that could be looked at.

I was always lead to believe that starting at 39, the maximum of the prior "range" would always be summoned on cast, thus static as charts indicate. We shall see I guess!

Not static.
