Armor piercing is a priority attribute for shooting hunters. Wait until your armor penetration reaches 800, then consider overlapping armor penetration. Now, let's use the survival hunter. Survival depends on crit and agility. When your armor is below 800 and your attack strength is below 5300, the survival dps is higher than shooting.

If you want to shoot the hunter's sunder armor, you can practice a jewelry processing skill, so that you can insert three +34 sunder armor gems into your body, and then go to the Seine, 25-person ice crown city, 1 region: 1 king's one-handed axe, ring, two king's bows, three king's wrists and four king's ornaments (+148. Zone 2: 5 king belts, 6 king shoulders; Zone 4: Rings, cloaks, etc. of frozen dragons. You can exchange the frost brand for the cloak and breastplate of 264 armor.

If it's all rags, you have to play Iceberg Castle in hero mode and get 277-level equipment, or the equipment mentioned above. However, it doesn't make much sense for you to pile up the pieces. When making a copy, the warrior tank will have the ability to break the boss defense, and with buff, your output is already very high. It takes too much money and energy to pile up the fragments in order to improve the dps of less than 10%. I suggest you stack it to around 1 100.
