Why can we not equip this armor? Most armors are race and class specific, please check if you are of the correct race and class as listed on the armor. What are soul stones?
Soul stones are items that can be socketed into your equipment so as to provide Stat boosts to the person equipping them. As with armor and weapons, soul stones have a Required rappelz-item.com/tag/level/">level and will not provide the given stat bonuses unless the user meets the requirements.
What is soul power? Soul power indicates the "charge" left in the soul stones socketed into your equipment. If you have no soul stones, the soul power should read 0%. The moment you socket a single soul stone into your equipment, the power rises to 100%. When soul power depletes i.e. reaches 0%, the stat bonuses provided by the stone(s) in your equipment will be negated.
Do note that the reduction does not scale according to the amount of soul power you have. If your stone gives +10 Strength for example, and soul power is at 50%, it will still give +10 Str, regardless. Only till the soul power drops to 0% does it stop providing the bonus. Do note that using equipment reduces the soul power in them, this is inclusive of equipment used by pets.
