A note about Stunguns.
I find as long as I'm not trying to do an entire team at once, I've found Stunguns just from the GET-1 & Shard Stores come often enough to bank them up fairly regularly.
I have over 200 now as I'm saving for SLKR who wants 400.
The key is buying them in GET-1 store & NOTHING ELSE, lol, I kept buying them even when I was working on Malak & GAS if I needed them bad enough.
And I'm doing them now even though I need Hermit shards. I only buy 1 stack of 10-15 Hermit after each TB since I'm not in a rush & the rest I just slow buy the Stun Guns whenever they pop up.
My issue is the Carbantis that go with the Stun Guns, we get them 3x a week for about 55-60 or so & its no where near enough.
I am constantly buying Carbantis with Guild Tokens just because so many toons end up using them in all sorts of combines at higher levels in addition to the typical G7-8-9 single use ones.
Those and Mk8 Eyeballs which are constantly needed 3x at every G11 it seems.
