HP stands for Health Points, Freshly minted Sneaker has 100% HP, HP of a Sneaker decays as users spent Energy and use this Sneaker to move. HP of a Sneaker does not decay if users only use this Sneaker to provide Energy.
The Sneaker HP decay rate* is affected by:
Comfort value (Base Comfort, added Comfort via leveling or Gems), the higher the Comfort value, the slower the HP reduction.
Sneaker quality, the higher the Sneaker quality, the slower the HP reduction.
The amount of the Energy used is proportional to the HP reduction.
* From the moment a Shoebox is opened and a Sneaker is revealed, HP will not decay for the first 48 hours. The 48 hours grace period will become invalid if the Sneaker is transferred/listed/traded.
HP needs to be restored via burning GST and Comfort Gems. If left unattended, following penalty applies:
HP < 100% = Sneaker cannot be listed on Marketplace or transferred away.
HP < 20% = Sneaker cannot be counted to provide energy in that Realm.
HP = 0, Sneaker cannot be used for moving.
To restore HP, user needs to burn GST and Comfort Gems. The higher Sneaker quality, the higher the cost.
Note: Sneaker HP will restore to full after user level from Level 24 to Level 25.
