I have read some forums and it says I required 919 as an I/L mage with 30 Blizzard to 1 hit ULU 2. I have 950 magic with blizzard 30 and for some reason it doesn't 1 hit. Can anyone help please?
Are you using an elemental wand 7 (blue)? It gives bonus damage to ice attacks. I think the numbers in the leeching guide are written with that assumption in mind.
