Stealth

Summary

Must have at least 80 Hiding to be able to Stealth
Players gain (5 + (10 * (Stealth Skill / 100))) Stealth steps per Stealth activation
A player will leave footprints behind when using their last 5 steps
If a player has "Auto-Stealth" turned on (which is on by default), players will automatically make a Stealth activation when moving while Hidden, after the Skill Use Timer has expired (10s).
After the Hiding Skill Use Timer has expired, you will receive a system message indicating "You feel comfortable enough to begin stealthing."
While stealthing, if you have moved more than your available steps before the Stealth Skill Use Timer has expired (10s), you will need to wait to continue stealthing. You will see a system message "You feel ready to continue stealthing", when you are able to continue without revealing yourself.

A player who is currently hidden can make a Backstab attack against creatures in their weapon range
The player must be hidden through use of the Hiding skill (and not Invisibility spell) and have activated Stealth at least once since becoming hidden in order to be able to make a Backstab attack
Players must have at least 80 Stealth skill and 80 skill in their equipped weapon in order to make Backstab attacks
A player's accuracy when making Backstab attacks is +25%
Players have a +25% chance to inflict poison from a weapon when making Backstab attacks
Players have a +25% chance to perform a Weapon Special Attack when making Backstab attacks
If a Weapon Special Attack occurs while making a Backstab attack, and the effect has a duration (such as for Fencing and Macing), the effect will last for the maximum duration possible (i.e. treated as being made with a very slow weapon)
The Damage multiplier for Stealth Backstabs is +550% to +1100% (based on weapon speed)
Backstab damage is further scaled by (Stealth Skill / 100)
Players attacking other players from stealth will make the same Backstab sound effect, but they will receive no bonuses to the attack
Relevant skills have 10x their normal chance to result in a skill gain when a Backstab attack is made.
After a player makes a standard (non-Shadow Aspect) Backstab attack, their chance of inflicting an Aspect Weapon Effect is increased by +50% of normal for the next 30 seconds (this bonus will also be shown in [Stats while it is active)
