Not true. Archer's ring increases range +5, Seers ring is mage +5, and Berserker's ring gives strength +5. They're all too expensive to be worth it though. Well it's +4...and also there is warrior ring, which gives +4 to slash bonus and defence (Archer and Mage give +4 Defence to Range and Mage, respectively.) So it is very nice if you have a whip, and is only around 800K.
