Hi, iam making my first Lighntning Assa, and i have no idea.

1: Shadowmaster: which damage has it? The same as I am making? so i should wear claws?
2: i can make 5 Traps or? Does fast cast rate or faster attack changes anything?
3: What should i do for light immunes?

Thx a lot ;-)

1. It’s randomly based on the skill level of the shadow master, to my understanding it spawns its own gear on each cast

2. It is based on increased attack speed of your main hand claw (if using claws) if using weep/shield it is based on the attack speed of the weapon.

3. Fire blast or death sentrys corpse explosion

I wouldnt use shadow master for a trapsin playthrough. FCR is not important but it affects your mind blast which I recommend you use in Hell, it is a life saver. I usually lay 4 light traps and 1 death trap and then use fire blast and merc with mind blast to deal with immunes. Its a pretty safe character to beat hell with because of mind blast and merc.

This one is pretty good for starting out if you dont know what to do.

3. infinity would be the goal.

yeah this is good if you're on ladder but if you're just trying to pvm the old fashioned way this is pretty much out of the question in my experience

thx a lot for the answers.
add increased attack speed: so i can llay for example 7 traps if i have more attack speed?

No 5 max
