act 2 nm might merc + ecv/eca pride for damage
i find that using infinity is better if your killing mobs/bosses because the conviction lowers monster def by % and infinity has crushing blow
if your doing a lot of teleporting you can just swap on insight because barbs usually have low mana pool and only have mana when leaching off other monsters. but if you do use pride you have the issue where pride does have a cham rune so monsters shatter and you cant loot for potions but its also a nice feature to keep monsters from respawning or used for corpse explosion.
