The Pirate Invasion is an event where numerous pirates invade the spawn point. It can occur in Hardmode randomly or by using a 海盗地图 after an altar has been destroyed and the player has 200 or more max health. If those requirements have been fulfilled, there is a 3.27% chance if one has yet to be defeated, and a 1.96% chance if one has been defeated.
- The 鹦鹉 will fly about, trying to deal contact damage. It does not drop much and killing one will not help complete the event.
- The 海盗船长 uses a gun and a cannon. The gun rapid-fires bullets, and the cannon will fire projectiles that explode on contact with a solid object, dealing very high damage. The captain drops a vast amount of loot. Only one can exist at a time.
- 私船海盗 are the sword-wielding scalawags. They deal melee damage and move fairly rapidly. They drop even more loot than the Captain.
- 海盗弩手 are one of the ranged pillagers of the event. They use their crossbows to fire flaming arrows from a distance. They drop the same amount of loot as their low-class cousins (all but the captain, his parrots, his ghost, and his ship). With their debuff and considerable damage, they are one of the larger threats if in the open.
- 海盗神射手 carry bullet-firing guns. They are very inaccurate and are likely to miss. Nevertheless, one should take care to avoid their bullets if in the open.
- Unarmed 海盗水手 can only attack via contact damage.
- 海盗诅咒 are the skeletal remains of the captain. They appear after the captain dies. They act like wraiths, flying through blocks, and are immune to traps. Specifically designed to thwart exploitation of the grounded enemies, these are a large threat to those in enclosed shelters.
- The mini-boss of the event, the 荷兰飞盗船 has four cannons that fire towards the player, and goes down once all four are destroyed. The Dutchman has the highest chance of loot drops.
Do not attempt to fight the Pirate Invasion in an open space during early Hardmode. The amount of enemies coupled with their abundant projectiles will quickly overwhelm an inexperienced or underequipped player. Instead, consider some simple preparation. With a secure, enclosed space, the event can be made easy. Simply construct a box-shaped building on or off the ground. When inside the box, no enemies will be able to reach the player. Attacking enemies will require weapons that can attack around or through blocks. If the player does not possess such weapons, their only option will be to place holes in the walls and fire projectiles through them, taking care not to be hit by enemy projectiles. It is best to place these holes in ceilings or floors to make it harder for ground enemies to fire into them. The Flying Dutchman cannot pass through blocks, so it will remain stuck against the walls of the box where the player can easily destroy its cannons. Do note that the Pirate's Curses, with trap immunity and the ability to fly through blocks, will be a large threat to those in shelter. It can help to make the shelter larger for space to dodge and fight the Curse.
- 钯金盔甲 can be used with the corresponding head piece for regeneration.
- 山铜盔甲 can be used with the corresponding head piece for crowd control.
- 钛金盔甲 gives the most defense and should be used with the corresponding head piece.
- If one does not mind hybrid sets, warriors and rangers should use the寒霜胸甲, 禁戒裤, and their corresponding Adamantite Head piece.
- A mage can use the 巫师套装 with the 禁戒裤, however, this is very frail. Otherwise, a wizard should use 精金盔甲 if the other sets are unavailable.
- A summoner should use 蜘蛛盔甲 with the 禁戒裤. Summon all minions with Spider armor, then switch to the Treads for one more.
For Melee Users
- The 钛金剑 is useful as it has high damage. If it is unavailable, the 精金剑 can be used. The 冰雪镰刀 is also useful.
- The 冰雪悠悠球 is useful due to the 霜冻减益. Yoyos as a whole are useful for attacking from within shelter, though they have limited range.
- The 精金关刀 and the 钛金三叉戟 are good piercing weapons.
- The 飞刀 is useful for attacking from within a safe box.
- The 太极连枷 can be used to disrupt enemy lines due to the 困惑减益.
- The 暗影焰刀 can be used at range against both crowds and single targets, but requires the defeat of a Goblin Summoner during the Hardmode Goblin Army.
For Ranged Users
- The 骸骨弓 and the 冰雪弓 (with 诅咒箭 or 毒液箭) are all good bows. Even the 地狱之翼弓 (with the 无尽箭袋) is still useful due to its infinite pierce.
- The 发条式突击步枪 (with 水晶子弹 or 灵液弹), the 玛瑙爆破枪 (with 灵液弹), the 凤凰爆破枪, the 星星炮, and the 乌兹冲锋枪 (with the 无尽火枪袋) are excellent choices. The 巨兽鲨 (with the 无尽火枪袋) is even better if The Destroyer has been defeated.
- The 飞镖步枪 / 飞镖手枪 and the 毒弹枪 are great for debuffs. Use 灵液镖 for single targets, 诅咒镖 for singular enemies, and 水晶镖 for crowds. The 火焰喷射器 is also good if one has beaten Skeletron Prime.
For Magic Users
- The 寒霜之花 is useful for debuffs. The 火之花 is a weaker version.
- The 夺命杖 is great against crowds, while the 爬藤怪法杖 is useful for barriers. The 雨云魔杖 can be used for damaging passersby. The 寒霜法杖 is also good.
- The 黄金雨, the 诅咒焰, and the 水晶风暴 are all good weapons for debuffs and rapid damage respectively. The 恶魔锄刀 can be used for close combat.
- The 裂天剑 is a very powerful weapon and can deal high damage to both crowds and single targets. However, it requires a 魔法导弹, necessitating exploration of the Dungeon.
- The 蛇发女妖头 can attack multiple enemies at once if obtained.
- The 神灯烈焰 has homing and powerful damage.
- The 水晶蛇 is good against crowds.
- The 邪恶三叉戟 is a good weapon, but it is dropped by deadly 红魔鬼.
- The 魔晶碎块 is weak and possesses limited range, but attacks directly through blocks and is useful for attacking enemies stuck outside the player's shelter.
- The 蜘蛛法杖 is available early, and a solid improvement over the Pre-Hardmode options, especially with the spiders' ability to latch onto enemies (putting walls behind the arena can make the spiders more mobile). If the Dreadnautilus has been defeated, the Sanguine Staff is a very powerful option.
- For sentries, one should use the 蜘蛛女王法杖 as it is the best one available.
- Any food that gives the 吃得好增益 gives minor stat buffs to everything. Good ones are the 鱼菇汤, 圣诞布丁, and 南瓜派.
- 铁皮药水, 耐力药水 and 再生药水 will help tremendously with survivability.
- 敏捷药水 will aid in dodging.
- 弹药储备药水 and 箭术药水 are good for rangers.
- 魔能药水 and 魔力再生药水 are must have for mages.
- If the player possesses a minion, a 召唤药水 will increase capacity by 1.
- 暴怒药水 or 怒气药水 are useful for almost all classes.
- 翅膀 are extremely useful for mobility.
- The 蛙腿 and its upgrades will dramatically increase the vertical mobility of wings.
- Mobility accessories such as the 克苏鲁护盾 are very useful as well.
- Damage increasing accessories such as any Emblem, the 机械 or 烈火手套 and 魔法箭袋 are always a good choice.
- Variants of the 钴护盾 and 十字项链 can prevent hits.
- 魔法手铐 are good for regaining Mana.
