Fairies.

There are some type of little companions you can have called Fairies. These are the following:
-Naiad: Obtainable through NPC Nell, by spending 10,000 TCoins/BCoins. Prevents dead when equipped for every charge on in (charge = every "+"). If the Naiad is +0 (or has no +) it will still prevent the dead but it will disappear. When dying the Naiad will use a charge and you'll get automatically full Hit Points and Mana, without neither spawning back in the last Town not any loss of Experience Points whatsoever. Doesn't count for Mount's Hit Point. It also casts Blizzard spell (exactly the same as Foema Class' spell), which damages and slows the opponent. Slightly improves the attack of your character (both types, melee and magic).
-Imp: Obtained in Zakum's Castle Quest, at the last room. Improves attack (both types, melee and magic).
-Grewpain: Obtained from the silver Dragon in Azran by paying 2 million Gold and having the following items in the inventory: 10 Snowballs, 2 Twigs, 4 Straws, 1 Hat and 1 Carrot. Improves attack (both types, melee and magic) and casts Blizzard spell.
-Hidden Ruin Angel: Obtainable through NPC Nell, by spending TCoins/BCoins. Used in conjunction with Casino Entrance Ticket to enter the Casino area through a Teleporter in Azran Town.
-Red Angel: Obtainable only through NPC Nell by buying a Jewel Pack, which costs 3,500 TCoins/BCoins. Increases Drop Rate by 32% and Experience gained by 16%.
-Gold Angel: Obtained by using Gold Flash on Red Angel, which can be bought from NPC Mai in Snowfield. Increases Drop Rate by 50% and Experience gained by 18%. Will automatically sell any items dropped by the character equipping it except Oriharukon and Latorerium Powders, which, by the way, will be stacked up to 120 in one Inventory Slot. You can sell items in your Inventory by pressing the Shift key and Right Clicking the item.
-Silver Angel: Obtained by using Gold Flash on Red Angel, which can be bought from NPC Farche in Erion. Increases Drop Rate by 32% and Experience gained by 16%. Will automatically sell any items dropped by the character equipping it except Oriharukon and Latorerium Powders, which, by the way, will be stacked up to 120 in one Inventory Slot. You can sell items in your Inventory by pressing the Shift key and Right Clicking the item.
-Green Angel I: Obtainable through NPC Nell, by spending 2,000 TCoins/BCoins. Increases Experience gained by 16%.
-Green Angel II: Obtainable through NPC Nell, by spending 4,000 TCoins/BCoins. Increases Experience gained by 32%.
-Blue Angel: Obtainable through NPC Nell, by spending 2,000 TCoins/BCoins. Increases Drop Rate by 32%.
All Fairies can be bought and sold to other players by trading or Auto-Trading.

-Trivia:
-Fairies that have a limited time of usage (like 7 Days, for example) will not decrease the time while you're not equipping them.
-If you're hunting Charity Boxes (or any type of Boxes) do not equip neither Silver nor Gold Angels, as they will automatically sell ANY items that are not Oriharukon or Laktorerium Powders, including Charity Boxes.
-You may refine Naiads, Imps and Grewpains with Powders, like if it was any weapon or armor, but you may as well refine them by using a Fairy Bless Water (bought from NPC Nell, by spending 200 TCoins/BCoins) up to +6.

Stay tuned as always!
