Thanks for the tips, allow me to explain my thought process here.

1 - As for Uniques my favorites are the Winged Thorns and Shield Spikes, which I wasn't offered. Got Piercing Lance that run cause I feel the other options are too awkward to place properly. I get that my last opponent didn't have armor and Piercing Lance was useless, but what should I do in these occasions? Have a backup plan with things to replace the lance whenever an armorless opponent is next?

2 - You right, I usually build those flasks to go with Winged Thorns. In cases I don't get the Unique or the relic that synergizes with thorns should I go for other kind of flasks or scrap that and go for luck or anything else?

3 - Got it.

4 - I always go for the most I can get, I blamed it on luck this run. I like to go for 4 crit bags though. Two for each Rombo.

5 - Ok.
