Stonereaper vs. Modti's Depravation!

Which is better, i need advice on which of my beautiful curses staffs to use

Stonereaper (current, favoured);
Energy +10
Dark Damage 11-12 req. 9 curses
1/2 recharge curses (20%)
1/2 cast time all spells (20%)
Energy +5
Curses +1(20%)

Modti's Depravation (new);
Energy +10
Cold Damage 11-12 req 9 curses
1/2 skill recharge time of all spells (20%)
1/2 cast time of curses (20%) x2 (wtf?)
Health +30

help me choose pleeease

I think I like the Stonereaper more. 4x faster isn't that great anyways. Also, Dark Dmg > Cold Dmg.

cool, anyone else want their say on it?

Wait, are you saing Modti's is
Halves Cast time of Curse (20%)
Halves Cast time of Curse (20%)
?

How about cold damage to activate Spinal Shivers? Puts a point in Modti's favor if you ask me

If your staffing to interupt:

1) Your build makes you run low on energy
2) Your team mates dont have cold weapons, making this skill close to useless.

Yep, I expect there is a staff like this for every caster proffesion.

Neither: HCT for the Curses skill tree is the worst mod availble. Who needs faster casting time when all the good Curses spells have 10+ second recharges?

Use 2 HSR Mods. The best set is a +5e^50%/HSR 20% Wand and a HSR 20%/Curses +1 20% focus.

So... Stonereaper wins?

I agree with Gatecrasher, cold damage for Shivers.
The 'original' Curses staves do dark damage and you have to switch weapons for interrupt.

The +1 20% on Stonereaper is also very nice.

For general Curses I'd say Stonereaper because of the +1 20%.
For any Shivers build Modti's Depravation.
