Hello guys. I've been wanting to do a crystal guide video for a while and finally I got around to voicing one this time so bear with me as this topic can be somewhat complicated. Some crystals are stackable: Anarchic (Blue - Boss Damage Reduction) Stalwart ( Blue - Normal Mob Damage Reduction ) Vigorous (Blue - HP Restoration) Mutinous (Red - Boss Damage Inc. ) Hunters (Red - Normal Mob Damage Inc.) All of the above are stackable crystals. Everything else is not either not stackable or doesn't matter/useless to you. THE MAIN POINT TO TAKE FROM THIS is your crystals for your ROLE are almost NEARLY IDENTICAL ALWAYS. There is no reason a DPS class should be wearing garbage crystals as the crystals listed in this guide are affordable and provide a ridiculous dps boost for ANY DPS class. I.E. All DPS classes will use something similar to Savage, Acrim, Focused, Carving or Forceful for BOSS fights...pretty much NOTHING else. Don't use Resolute or Virulent or any of that other garbage as DPS for crystals. Only exclusion would be Kelsaik's nest where you will stack 4 mutinous cruxes. Remember, crystals can break if you die. So if crystals are too expensive for you, buy the white version of the crystal (the version that doesn't have "Fine" in the first part of it's prefix e.g. Vigorous Crux instead of Fine Vigorous Crux), then buy a cheapo crystalbind (One that lasts for an hour with a 10 minute cd). Don't toy with your crystals, as they can get expensive if you don't invest in CB's. Anyways, make sure you leave your feedback and let me know if I've missed something. This should point newer players in the right direction for crystals setups. As a side note, do not forget to use CRYSTALBINDS. Not COMPLETE CRYSTALBINDS (Unless you have a lot of money). Use them to circumvent the breakage of crystals! If you are questioning if attacking from behind is a reasonable strategy, this spreadsheet will probably change your mind: https://docs.google.com/spreadsheet/ccc?key=0AruR3IAIMmYCdEdjQmxzT0EwVUFPUXR0X052cWVEMGc&usp=drive_web#gid=0 Not sure if I will do a PVP crystal overview as I only concern myself with dragons and stuff.
