Freezing, Burning, and Poisoning Spells...

[TemjinGold]

Hey guys, I was wondering if anyone knows offhand if it's true that all spells that have freeze, burn, and poison percentages are "chance to" do the associated effect. I've undertaken the "clean up the Engrish" project on my files and am up to spells so I want to clarify that if it's true (currently, the descriptions make it sound like flame arrow, poison skull, fireball, etc. ALWAYS apply the effect.) Thanks!
