This is a beginning idea,this is something I want to start with and nothing is final in this suggestion.
caster claw (youre welcome to suggest names)
dam 75-101 (this damage doesn't include spells does it?)
delay 27
120 primal
100 power
_____________________
ranged only spells only
25 dps +100 attack skill (25 dps because currect one and only tech kit deadly V increases spells damage by 15 dps)
_____________________
10% chance:
cooldowns and delays reduced by 5%
duration 30 sec
OR
10% chance
Next ranged spell does 150% of normal damage
removed after 1 use
_____________________
5% chance lesser spirit shield (but spell version) maybe ethereal shield? (something suitable since it comes from shaloth)
Incomming spells only
0 damage removed after 2 uses
duration 30 sec
