Howdy, Lillu suggested I post this here for fixing.
Currently there is a bug with the amount of damage/leech the SK line of tap spells do.
Lv47 - Life Leech - 228 DMG
Lv51 - Siphon Life - 150 DMG
Somebody suggested that the LV51 spell is unresistable, however on the allaclone they both show the same resist (Magic -200).
Thanks for taking a look.
