Dynasty Warriors 4 PS2 Orbs Fire Orb (**): Adds fire damage to attack. Enemies receive damage while they are on fire. COMMENTS: Fire damage increases as Orb level increases. Ice Orb (***): Temporarily freezes enemies, immobilizing them and reducing their defense. COMMENTS: Chance of freezing enemies increases as Orb level increases. Lightning Orb (**): Lightning strikes nearby enemies, knocking them down. COMMENTS: Lightning damage increases as Orb level increases. Blast Orb (*): Damages enemies even when guarding. COMMENTS: Block damage increases as Orb level increases. Vorpal Orb (****): Increased damage, chance to kill non-general enemies instantly. COMMENTS: Chance to instantly kill enemies increases as Orb level increases. Here are other items Peacock Urn (***): Increases Life gauge. COMMENTS: Initially useful if your character has a short life gauge. Once you start getting Dim Sum, I'd recommend switching to the Tortoise Amulet. Dragon Amulet (**): Increases Musou gauge. COMMENTS: I haven't found having more Musou to be particularly useful, especially since the effects of Orbs is dependent on your Musou gauge being full. The shorter your gauge the faster it will fill up. It's better just to get Musou Wine power ups instead. Tiger Amulet (****): Increases Attack. COMMENTS: Unlike previous games, the attack boost here is significant, especially at higher levels. This gives weaker characters a good attack boost, and makes stronger characters real powerhouses. Tortoise Amulet (****): Increases Defense. COMMENTS: Like the Tiger Amulet, the Tortoise Amulet significantly boosts defense, especially at higher levels. A high defense not only decreases the damage you receive but also increases your resistance to being stunned by attacks. There is no reason why you shouldn't have one equipped at all times. Speed Scroll (***): Increases Speed. COMMENTS: The speed increase is not very noticeable unless this is at high levels. It provides a one step boost in speed at level 20 (i.e. from very slow to slow, or from fast to very fast). Wing Boots (*): Increases Jump ability. COMMENTS: Slightly increases jump height. Not too useful. Huang's Bow (*/**** with Huang Zhong or Xiahou Yuan): Increases Bow Attack. COMMENTS: Not too useful unless you are playing Huang Zhong or Xiahou Yuan. This affects their Charge attacks as well. Nanman Armor (*): Increases Bow Defense. COMMENTS: Considering that arrow damage has been toned down significantly, this item isn't too useful. Horned Helm (*/**** with Ma Chao): Increases Mounted Attack. COMMENTS: Not too useful unless you are playing Ma Chao. Ma Chao + Horned Helm + Calvary Armor + Storm/Shadow Runner = Good stuff. Calvary Armor (*/**** with Ma Chao): Increases Mounted Defense. COMMENTS: Ma Chao + Horned Helm + Calvary Armor + Storm/Shadow Runner = Good stuff. Seven Star Sash (*): Increases Luck. COMMENTS: It seems that items you receive in battle are determined more by random luck rather than luck itself. The jury is still out on whether or not this item actually does anything. Elixir (***): Musou gauge fills faster. COMMENTS: A good item in conjunction with the Way of Musou item. Herbal Remedy (***): Increases Charge Attack effectiveness. COMMENTS: The usefulness of this item depends on how often you use charge attacks. I would recommend using the Charge Bracer instead if you have it. Art of War (*) Effect: Increases the duration of power up items. Stage Found: Campaign against Sun Jian REQUIREMENTS: Enter the north castle before enemy reinforcements arrive. Defeat at least four of the following generals: Sun Quan, Sun Shang Xiang, Zhou Tai, Lu Meng, and Gan Ning. A supply team will appear from the entry point at the north castle and move towards the southern castle entry point. Defeat the supply team for the item. COMMENTS: Not very useful. Survival Guide (*) Effect: When life is critical, Attack x2 when knocked down. Stage Found: The Two Qiaos REQUIREMENTS: Rescue in order Da Qiao and Xiao Qiao for the item to appear later when you approach the escape point. COMMENTS: Not very useful. Bodyguard Manual (***) Effect: Bodyguards become stronger. Stage Found: Guan Yu's Escape (Liu Bei's forces) REQUIREMENTS: When Xiahou Dun arrives do not backtrack to him. Defeat the fourth gate general when Xiahou Dun is near the bridge in front of the fourth gate. Fight Xiahou Dun on the other side of the final gate and the item should appear. Thanks to NyteWalkyr for the clarifications. COMMENTS: This is a great item for bodyguards in training, as it will significantly extend their life expectancy. For elite bodyguards it makes them practically godlike. Way of Musou (***) Effect: Can use True Musou attacks regardless of life. Stage Found: Guan Yu's Escape (Cao Cao's forces) REQUIREMENTS: After you pass the 5th gate a supply team will appear east of the bridge in front of the fourth gate and head eastward. Defeat the supply team for the item. COMMENTS: In conjunction with the Elixir this can be useful. For some reason True Musou attacks don't seem to be as effective this time around. Power Scroll (*) Effect: Won't lose weapon deadlocks. Stage Found: The Yellow Turban Fortress (Yellow Turban forces) REQUIREMENTS: Defeat Guan Yu and Zhao Yun. A supply team will appear to the northwest and move to the northeast entry point. Defeat the supply team for the item. Comments: Limited usefulness. Wind Scroll (****) Effect: Increases attack reach. Stage Found: Battle of Xu Chang (Shu forces) REQUIREMENTS: Protect Yue Ying until she sets up the ramp vehicle, and defeat Xu Zhu when he ambushes the supply camp in the southwest. When Sima Yi remarks on the two plans failing the item will appear in the northwest. Comments: This significantly increases the range of your weapon. It's extremely useful for characters that have very little range. For characters with an already long-range weapon it makes them into absolute monsters. Fire Arrows (*/**** with Huang Zhong or Xiahou Yuan) Effect: Arrows become fire arrows. Stage Found: Unification of Jing (Wu forces) REQUIREMENTS: Before the enemy generals join forces, defeat Wang Lang's sub general Zhou Xin for the supply team to appear at the west castle. Defeat the supply team for the item. COMMENTS: Fun to play with but ultimately not very useful, unless you're playing as Huang Zhong or Xiahou Yuan. This item upgrades their Charge attacks to fire arrows. Charge Bracer (***) Effect: Charge attacks cannot be stopped by normal attacks. Stage Found: Campaign against Sun Jian (Yuan Shao's forces) Requirements: Enter the north castle before enemy reinforcements arrive. A supply team will appear south of the castle and move towards the entry point southwest of the castle. COMMENTS: If you use Charge Attacks frequently this is an excellent item.
