Insignias

Alright, so I've been doing a bunch of different speedclears on my assassin. I've got a couple sets of armor that I use for different things now, but I've always had one question. Some people tell me to use Blessed Insignias and some say Vanguard or another sin based one. Blessed Insignia says +10 armor while enchanted, which is pretty much all the time considering I'm permaing. Now, Vanguard says +10 armor (physical) and +10 armor (blunt/whatever it is). What is the point in using Blessed over Vanguard? And what are the advantages over each other, any help or someone's insight on this would be appreciated.. thanks!

10armor is 10armor to everything, 10 to blunt is only 10 to blunt. Blessed would be better, but it's also a lot more expensive. Also if you farm a specific place, you might not need complete armor. For example when farming mantids, all you need is +10 to piercing. If you're looking at a build that's made for farming a specific place(vaettir, raptors, mantids etc), then they might recommend insignias for that particular place, but for general play you probably want blessed.

vanguard is +20 vs blunt dmg, and +10 vs non blunt physical dmg. so in some cases, like ToS in FoW, vangaurd provides you with more armour against the abyssals, without lowering your armour against rangers, which is obviously useful.
so if your struggling with a particular area, check what damage is being done to you and consider changing the insignia's. blessed is still useful though, because you dont suffer a drop in armour as you change enemies, which you would if you ran vanguards into burning forest.

I'd say that Blessed would be the choice if you are constantly enchanted (like a Perma).
