Meditation

Summary

The baseline Mana Regen rate is 1 mana restored every 2 seconds (i.e., 0.5 mana per second).
The maximum Mana Regen rate is 1 mana restored every 0.5 seconds (i.e., 2 mana per second).
The minimum Mana Regen rate is 1 mana restored every 8 seconds (i.e., 0.125 mana per second).
Players who use the Meditation skill will always enter a Meditative state (regardless of skill level) that doubles their current Mana Regen rate
The Mana Regen rate is increased by (100% * (Meditation skill / 100))
The Mana Regen rate is increased by 100% if the player is actively meditating
The Mana Regen rate is penalized by (2 * (player's Total Armor Meditation Penalty))
A player's Total Armor Meditation Penalty is equal to the combined Meditation Penalties of all armor worn
Each piece of armor a player wears has an Meditation Penalty equal to it's (Armor Location Penalty * Armor Material Penalty)

The Mana Regen rate is adjusted with Meditation rate Mastery Chain links
- Example: If the player's Mana Regen rate is 1 mana every 1.0 seconds, having a 10% increase would boost it to 1 mana every 0.9 seconds.

Shield	Chest	Legs	Arms	Helmet	Gloves	Gorget
35%	35%	22%	15%	14%	7%	7%

Image	Material	Penalty
	No Armor, Leather Armor, Buckler, or Wooden Shield	0%
	Studded Armor or Wooden Kite Shield	20%
	Bone Armor or Metal Shield	40%
	Ringmail Armor or Bronze Shield	60%
	Chainmail Armor or Metal Kite Shield	80%
	Platemail Armor, Heater Shield, or Chaos/Order Shield	100%

A player wearing a suit of all studded leather but with a platemail gorget would have:

(.35 * .20) + (.22 * .20) + (.15 * .20) + (.14 * .20) + (.07 * .20) + (.07 * 1.0)) = 25.6% Total Armor Meditation Penalty.

Which would result in a (2 * 25.6%) = -51.2% effect on their Mana Regen rate.
