Best bang for buck AC/HP survivability item?

[Byrjun]

Level 60 and Torpor.

But barring that, definitely the rings. Next I guess would be the Dusty Rusted Vambraces, but really difficult to find for sale since they're so heavy (but you'll get a pair yourself if you solo HS ent at all). Next would be a Hooded Black Cloak and then Black Sapphire jewelry. The best thing you could do, especially if you're lower level, is buy a fungi, but that will probably be out of your price range. Clay Guardian Shield is a really good value item but hard to find for sale since it's so popular.

I've stacked my SHM for AC/HP as well. Thoughts-

Clay Guardian Shield is indeed a good value secondary item. 1-1.5k range

Goblin Parrying Spear for your range adds 4ac plus some wis I think- dirt cheap

I'm currently rocking Silver Plated Leggings for the AC over gatorscale or black chitin

Swapped my Plat Ruby Veil for Mask of Wurms- affordable alternative to enshrouded veil, cheaper than targishin mask too, adds HP & mana

HBC- these have gone up in price recently but you're definitely capable of camping it solo with epic. Just gotta know where to lev over the wall to get to the camp. Best back slot other than Hiero Cloak

If money's too tight for Fungi you can always go with Iksar BP for the regen. Still pricey but before Torpor at 60 you can never have too much regen
