@klausiboyer: If I remember right, there's only a chance to receive the item. On the other hand, the chance of each of the bonus bosses carrying their respective item is 100%, and you can steal it off before you kill them.
@Nassun: Money will be used later in the game to buy scrap metal in bulk to upgrade your items. The Wiki is made through player contributions and edits, and will grow as more people finish the game to the end and add to the information.
@ Dbag26: The higher your speed is, the faster you will be after Speed Up is cast on your character (so that a 1000 speed character will still be faster than a 500 speed character even after both receive speed up)
D: "Oh, not this again!" Kaz: "Well, why don't you stop bumping into them?"... Mari: "Good luck everyone!" Kaz: "I don't need luck!"... Kaz's lines are the best :D
@Ichtyic: I beat Koohii before upgrading my (vampiric) weapons to Tier IV; My characters have finished a good portion of their character tree, but have not actually maxed (6 more class blocks to fill); I used Last All, some Start Alls, and left my Dice equipped. I spec for Speed and Attack as my primary stats, and try to avoid HP as much as possible. My character HPs range from 2300 to 3200. Beat Koohii with relative ease. Try using D's Autoraise for some survivability, and using Bahamut for buffing?
@joeyknish: Most fights would be that way; but boss fights drag on for quite a long time. Koohii is especially difficult until you grind for levels for a bit. In fights like those, being able to wear down the enemy while staying alive is one way to go. Though I used 500 as an example, realistically at the endgame your characters will deal 1500 and higher; which is 150 HP from each hit. It doesn't mean that you'll be invincible, and you certainly won't heal to full from each turn; but it's one style of fighting. Not that having attack boosting items is wrong, but it's just another way to style your party.
@joeyknish: The balance with Vampirics is that you heal through damage. Though you may not deal as much damage, you can slowly heal while dealing damage. I've a team built solely to be fast and deal high damage, and have purposely avoided optional HP upgrades when possible, and have still cleared the game (Koohii included).
If you cast AoE or use multi-attack moves, you get HP from each of them. So if you deal 500 damage to 4 enemies via Cleave, you receive 200 HP.
@jjjoahu: Rubies (and Sapphires) are rare gems; over the course of the game, you'll probably get just enough for all 4 of your characters to have an IV tier weapon. I remember getting 1 from the very final quest, and 1 from Mercenary Defense; the other 2 may have come from monster drops or quests.
@BigChief014: There are three skills that deal with this; Sprint, Hide, and Flee. When you cast Sprint you can run past a good majority of the enemies in any given room, and when you cast Hide, enemies don't attempt to chase after you. You can also cast both and use them simultaneously. In the chance that you do bump into an enemy, you can cast Flee to run from battle. And if you don't like the chance of success from Flee, you can equip Dice to your characters to increase their Flee success.
@Ichthyic: All the defense games in CSII are beatable. I'd have to say that they're easier in comparison to CSI's.
When you acquire a mercenary coupon, it allows you to use that type of unit. The coupons you buy in the shop are enhancers.
@ abyssoft: If monsters get to act at the same time as your characters, and you stun them, they get to pull off a move before the stun takes full effect.
