linking the spread sheet again just for ease of description
small note this sheet does not include the effects of enemy resil but it still shows what is biss.
in this sheet it shows the "effective dps" this means you should be doing this much dps in a bg if you are spaming the ability. so when choosing gear u want the gear that gives you the highest effective dps with sacrificing the least amount of stam.
as you can see the effective dps of changing red riding gloves to serpent gloves increases the effective dps of his spells. serpent gloves also have more stam so thus they are clearly bis.(row two)
now we look at changing the cloak to sorcerers cloak (row three) and we see that the effective dps goes up again . you also have more stam thus again it is a no brainer.
next we look at the effects of ivy cloth bracers (row 4) and we see that effective dps goes up again. the other option is mindthrust bracers. swapping to these is also better than crystaline cuffs but not quite as good as ivycloth. in this situation you trade like 4 stamina for 1 int. so the choice is up to you.
next we look at changing stillwaters signet to dpr. (row 5) your dps drops from this so clearly it was a bad choice unless you are using the ring to hit cap.
after that i looked at changing rings from stilwaters signet to garoshes pardon or bronze band of force (row 6 and 7) as you can see both are better but you loose 5 stam for that 1 int of bronze band of force. Here is another example of trading stam for int. choice is up to you.
lastly all the other changes i tried in the remaining rows all lowered dps so they were "bad changes".
in case you are miss reading the table, in row four i put the changes in "" marks then in the next row i just typed out "" + ect the "" marks just mean include the changes from row four that are in "" marks in this box. that way i took up less space.
so the changes to get the max dps at row 6 the highlighted row. you would change bracers to ivycloth of int , cloak to random dungeon cloak of sorcerer, gloves to serpent gloves, and stilwaters to bronze band of force.
yet again you can change out bracers for mtb and ring for garoshes pardon and still have better dps then before but gain about 9 stam
just re-read your post and i think i explained a lot more than you were asking for and probably u already understood it but i guess ill just leave it as is since it does answer your question
