some questions about srs

i have finally decided to use srs. first time i ever use this skill. i have checked some builds and passive trees so i think i know how to make this work.

i don't see much focus on casting speed on people's build and gear. isn't dmg reliant on cast speed the more skulls you have up the more dmg you do? how important is casting speed really?

1. i'm lvl 48 in cruel act 2 and can have 12 skulls up. is this normal? should i focus more on cast speed to get more skulls out?

2. what curse do people typically use with srs? vulnerability? flammability? punishment? what damage do they do?

3. i saw in a guide a recommendation to link hatred and haste with generosity? hatred i can understand but why haste? haste gives me cast speed as well so i can summon more skulls that i would normally be able to = more dmg. so why link haste to generosity?

4. got dying breath atm the stats seemed like they would be nice for srs. would 2 cast speed wands be better or something else? what do people typically use? there weren't any +2 fire staves for sale at this level.

1. Definitely you should. Use spell echo and get both skill duration passive clusters to get 20+ spririts in endgame.

2. They have a physical damage base with 50% conversion to fire, same damage composition as Infernal blow that we use. Now that they have 50% penalty on adding any kind of damage to it, Added fire isn't a good support anymore, however, minion damage is much better now and MPD is as good as ever. Curse usage depends on your build, an auramancer SRS build with all damage auras may use elemental weakness, however many SRS builds have problems with staying alive and decide on Temporal chains or Enfeeble.

3. Right, I wouldn't use generosity on Haste myself, possibly some do it because of socket problems.

4. Ideally, you would use a +2 fire, +1 all gems staff, that's your dream weapon. For an auramancer, Dying breath is good too.

For SRS the staff that raics said or Pledge of Hands. Anything else is not good for high lvl...

well i said i am level 48 in warbands so i meant for leveling no one has those staves for sale. there isn't even a pair of aursize on xyz yet. we have to make do with what we have. the league has only been running for 3 days :)

i meant if two cast speed wands would be better for leveling than dying breath?
i have srs in a +1 minion helm.
