42. Little bits of harmless arcane energy races across and arc between the surfaces of nearby objects nearby objects and creatures.

43. Glowing motes of energy flare up around the caster and slowly fade away.

 

[Kaffis]

[Ruined]

Here's a classic one for you:

45. Animals present near the caster (except for the familiar) sense that something is wrong and begin to whine, nicker, or growl as appropriate.

 

[Kilmore]

46. Some sorcerers have a "trademark". When Tierken the Burner casts one of his trademark fire spells, his body is enveloped in magical flame. Kandy Kayne's spells appear to be candy striped and smell like peppermint as they are cast. For a brief instant Bojongo appears to be a big gesticulating monkey as he casts.

47. Air temperature drops 20 degrees fahrenheit within 20 feet of the caster.

48. The air becomes grayish for all within 100 feet of the caster, though visibility remains the same.

 

[DerianCypher]

49. The Sorcerer hovers about an inch off the ground, his pupils turning pure white and begin to glow. An strong unseen and not felt wind blows at the caster from the front and lightning bolts strike the caster.

 

[I'm A Banana]

50. Every spell cast causes phantom ninjas to manifest, flip out, and kill people. Replace with pirates, hippos, wombats, or Tom Jones as appropriate.
