^^

It gives you a 20% chance of a +1 attribute level cast.

-5 damage is just that. You have a 20% chance to get 5 less damage from an attack. Most people prefer a more constant damage reduction, -2 while enchanted, -2 while in a stance, -3 hexed, or a combination of those.

Oh, please use full words when posting. Acronyms and abbreviations are annoying and easily misunderstood.

If your Fire attribute is at 16 and you have a Fire +1 (20%) equipped, then about 1 in 5 casts results in that spell being at 17 instead of 16.

So any of those % modifiers have that chance to trigger that effect when applicable - increasing an attribute when using a skill from that attribute, reducing damage, etc.

Thats like the easiest question to answer, you should be able to answer it yourself

***lol***
altho i agree ***whipes tears away*** i think a good rule of thumb is to not make fun of ppl's/newbie's Questions (as this is the Q & A section)
