Clear Celines campaign on at least Normal difficulty.
Unlockable: Difficulties
Hard Mode can be unlocked for use after completing the game on Normal Mode. If you then beat the game once more on Hard Mode, you can unlock Extreme Mode.
Hint: Stay Way From Counter-Attacks
When doing quests for new abilities, you may sometimes notice that the enemy you need to kill sometimes wont count for the quests quota; this is true if your weapon has the enhancement counterattack
attached to it.
Enemies killed through counter-attack damage will not be tabulated for your ability quest score. This is not much of a problem if you are fighting common enemies like Flesh Men, but if you have to destroy end-of-act boss enemies, you will want to use a normal SP-using attack instead of relying on counterattacks.
Hint: Keep It To Yourself
If you are playing solo and was wondering why you can purchase or find equipment meant for characters other than the one you are playing, it is for multiplayer on Xbox Live (play trading).
If you are playing predominantly solo (or just offline) sell all the equipment and accessories your own character cannot use (or an enchantment you dont want to synthesize), since each game file keeps the items in the idol box separated.
Hint: Potion Synthesis
Synthesize different potions with items for the following permanent effects:
Red Potion:
Removes last enhancement from item (small removes one, medium removes two, large erases all)
White Potion:
Removes all enhancements from item. SP recovery, SP use, damage, HP added, etc. should remain unaffected (not so with red potion synth).
Cyan Potion:
Increases SP recovery for accessories.
Orange Potion:
Increases attack of weapons.
Blue Potion:
Increases HP added to armor (defence).
Grey Potion:
Increases SP recovery rate for all items.
Panacea:
Eliminates any penalities from a flawed or cursed item.
HInt: Lost in Acts 3, 4, or 6?
Generally speaking, you will not be lost in Circle of Doom, but the randomized rooms can be confusing. New players will generally lose themselves in three common acts:
Act 3 Hall of Arrogance:
The end of the act will not appear until the party clears the Library of Memories (left path in Sunrise Atrium) and the Vestibule (right path in Sunrise Atrium). Once both sets of rooms are clear, the end of the act is at the top of the stairs in the idols room.
Act 4 Valley of Ice:
Each room has an exit that is on the second level of the dungeon. Locate a room with a ramp that goes up (there are only two variations of the ramp room) and while staying on the second level, head for the rooms exit.
Act 6 Dark World:
The paths are generally linear until the last room to the boss. Locate a spiral path going upwards; that leads to the boss door.
HInt: Mystery of the Rare
If you are looking for the "rare" enemies, you will find them in all the stages on Hard difficulty. If you want an easier time, make sure your character is around level 50 to 60 and playing alone (more players mean more pain).
HInt: Character Stats
A characters statistics are always preset to increase with the same application of experience points, thus growing a character into a front-line fighter, ranged attacker, etc.
