If I have a Greater Rift keystone in my stash, Can I still get a Trial Stone from a normal rift guardian?
Yes. Pretty positive you can hold an unlimited number of any combination of them. I've personally had 2 trial stones, a lvl 26 keystone, and a lvl 28 keystone in my inventory all at once. The only thing I can't confirm 100% is whether you can hold multiple of the same level keystone, i.e. 2x lv28's, simply because I just haven't done it yet. But I see no reason why they'd restrict this.
Sweet, Thank you. I gave in for the temptation, and used my keystone.. Hoping that it would solve the problem. I finished after the clock ran out, As i guessed... I got bored of running rifts (11 in a row without any trials).. But next time, If I get beyond my comfort zone, I can put it in my pocket, and let it wait until I am ready
If I get in over my head, Can I run like hell and tp back to town? Or do I have to fight until I win or die?
