You are given a wand when you first start Wizard101, which contains one of each 1 pip spell from each school (minus your own, but you have normal spell cards for that). By the time you upgrade from that one, you can usually find a wand that adds an extra pip in the first round - letting you progress straight to using 2-pip spells off the bat.
2 if you look at them they do NOT have the same power, proportionally storm snake is much more powerful than imp
I am talking about 3 life death and balance. And life rank 2 has more power than deaths so um yeah
If you do the math on hit point difference before and after the life and death, death usually opens a wider gap, as for some reason you didn't add in the healing that ghoul does. Usually, when you are throwing out 2 pip spells, a ghoul will usually get the job done almost as well, and with healing, probably better than life. Now if we do a 0-pip heal then toss the two pip'er, life works out better, but....
Ghoul does 160 and leprechaun does 155-195. Ghoul heals 80 though but you have to dived every heal in half so the pip rate works out and ghould does 200. But still 5 damage ddifference.
