New Life for Low Level Items
High level weapons are great for doing damage until you run out of SP. Rather than throw countless potions at it, synthesize a high level (Attack 100, 1000 or better) to a low level one found in the Forest of Embracing on Normal (the lower the better). The resulting synthesis will average the SP consumption, and with some luck, allow you to retain a measure of potency of your high level weapon (about 70% of it at worse).

Use Yellow Potions
Use yellow potions on high-luck characters just before a boss is killed. This greatly affects the quality of the item drops (more on Hard and Extreme difficulty levels).

Enemy Cycle
Did you find an enemy you need to harvest a great many of? You can use this exploit on solo (offline) mode. Get to the map the enemy spawns on and kill your fill. Before you load a new map, save and quit the game (anywhere). When you continue on solo mode, your character starts back on that map ... with all the enemies respawned.

Reducing SP Consumption
If you want to bring down SP consumption rates of your high end equipment, try synthesizing. High end SP recovering rings can be synthesized on your armor and weapons to reduce SP consumption.

Easier Quest Mobs
If you're looking for certain enemies in certain areas, try the following: every level is separated into regions, and certain mobs only appear in certain zones. Simply find the enemies you need and kill off everything in the area, including the enemies you need to kill. Then, head to the portal leading into the next region, but don't go through it. Instead, press [Select], quit your game (make sure to save), and then reboot your saved game thereafter. You'll have full energy, full SP, and be in the same region. What's more, all of the enemies you killed prior to the save/quit will be back. This is especially useful if you find an area that has an enemy or group of enemies that you need to kill mass quantities of.

Stay Close
When doing quests for new abilities, you may sometimes notice that the enemy you need to kill sometimes won't count for the quest's quota; this may be due to two things:

1. In the same Act and Area, but in different rooms. The powers of Collaboration and Spirit-Link will give you a rough idea how far you need to be for experience to count for "everyone in the fight". Generally speaking, characters in the same room will share the experience of kills.
2. Lag while online. Sometimes it occurs (especially for bosses). The best way is to get in a few licks (damage the boss) and make sure you're part of the fight before the boss gets cacked.

New Life for Low Level Items
High level weapons are great for doing damage until you run out of SP. Rather than throw countless potions at it, synthesize a high level (Attack 100, 1000 or better) to a low level one found in the Forest of Embracing on Normal (the lower the better).

The resulting synthesis will average the SP consumption, and with some luck, allow you to retain a measure of potency of your high level weapon (about 70% of it at worse).

Unlock Stone Golem
This hard to find enemy is the result of using an ability (Petrifying Breath) on the Wood Golem creature.

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 don't want to synthesize), since each game file keeps the items in the idol box separated.

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.

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 idol's 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 room's 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.

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).
