Frist off let me start by saying I went to warburg with my brute and my SG mates keep getting AS'ed so I made a stalker to find the tricks and here they are.
One of the best things u can do to stalker-proof is to have an aura running or be with someone that has one running. Here are of some of the auras. Repel, lighting field, blazing aura, death shroud, mud pots, repulsion field, hurricane, hot feet, artic air, chilling embrace and quills. Now this won't make u completly safe because only a couple of this are autohit chilling embrace being one. To help with this you could slot some of these with acc. These auras should keep the majority of the stalkers at bay however if the stalker is smart he could just pop some purple pills AS you then be on his way and some of these that just knockback or lower acc can still let a stalker through if he pops enough yellow or breakfrees.
Hope you enjoy
