Please Give Us a Way to Gamble/Buy Basic Charms in Endgame SSF

I'm level 92 Druid on T15-T16 maps. Not one staunching charm has dropped the entire play through. I'm sure I missed one at vendor during the campagin...my bad.

Feels bad that I can be this far into the game and not have a way to sure up a fairly basic defensive mechanic other than rely on RNG or use a lot of passive points to go far up/right.

Please allow us to gamble for charms with Ange...or expedition. or something... please...
Need a way to acquire basic charms (not even uniques) reliably in end game.


PS.
Life regen mod on monsters in higher levels maps is absolutely out of control. Needs to be tuned down.
