Ring of the Nile: The azure stone makes you feel ready for any situation.
Stat Bonuses: +4 SPD, +4 DEX, +60 HP, +60 MP
Fame Bonus: 5%
Feed Power: 900
This ring provides a healthy balance of survivability and power, great for players that like a faster pace with a little bit of extra health. Ring of the Nile is recommended for any Knight (with maxed Mana you can stun three times consecutively), and most of the other classes.
This ring is also a GREAT choice for Warriors, since not only does it give a fair amount of HP and MP, but the 4 Speed and Dexterity it gives will also be useful to the Warrior, since it benefits more from Dexterity than Attack. Note that the Berserk and Speedy status effects increase the attack speed of a weapon and the speed in tiles per second respectively, not the actual Dexterity and Speed stats.
