How do u make silverwood staff, thaumcraft 4

I been playing direwolf20 mod pack, mostly on thaumcraft 4 and eventually i got to state where i was going to make better wand/staff.

first thing i noticed is that staff vis cost for building is pretty high... im trying to make silverwood staff with thaumium wand caps but i need 115 vis to build this thing... and i noticed there is no wand that hold over 100 vis except that final wand that can carry 1k vis...

How do u make silverwood staff in thaumcraft 4??

i mean i made blaze...
