So with +1 to movement speed, you can take two steps where you would have been able to take one; with +3 to movement speed, you can take four steps in place of one. It works in exactly the same way extra shots does. The way the game actually calculates it is instead of a step taking 100 energy, it takes 100/(1 + movement speed) energy - so 50 energy for +1 moves, 25 energy for +3 moves, etc. To see what this means in practice, I'm going to give a short description of what energy means in the game. Every game turn, the player and monsters are given some energy - 10 points at normal speed, more or less if they are faster or slower. Then it checks who has built up energy over 100, and of those, the one with the most energy gets to move next. Once the player or monster has moved, they normally get 100 energy deducted, so have to build up energy again before they get to move again. But if a player has +1 movement speed, only 50 energy gets deducted per step taken, so they get to move again quicker. Note that movement speed only affects the energy used for movement - energy use for spellcasting, melee, using devices etc is still 100. __________________ One for the Dark Lord on his dark throne In the Land of Mordor where the Shadows lie.

My kobold ranger, Sparky, puts on Partial Plate Armour, and gets the message: The weight of your armor encumbers your movement. When he takes it off: You feel able to move more freely. I can see no differences in the stat page, nor do I notice any difference moving around the dungeon. (He's gonna wear that randart armor for now, regardless. It's nice: [40,+11] +3 Con, protConf, and +1 Light.)

No, armor encumbrance only affects mana.

Ha - didn't look there.

Ha^2 - it reduces his cl34 mana from 39 to 38 points.

"The weight of your armour encumbers your spellcasting"? "Your arms can move less freely for spellcasting"? "Casting spells feels more tiring with this heavy armour"? __________________ Dive fast, die young, leave a high-CHA corpse. -- You read a scroll labeled 'lol gtfo' of Teleport Level.

Each value of movement speed is very powerful (as I learned from personal experience when I picked up a sling with +4 movement speed): +1 movement speed is the same as having +10 speed, except it only affects the speed at which you walk. So if you have +1 movement speed and +10 normal speed you'll walk through the dungeon at what effectively amounts to +20 speed but you'll still do all your actions (fighting, casting, activating, quaffing etc) at +10 speed. Normal speed (or global speed since it affects your actions and your walking) stacks with movement speed. So when I found that sling with +4 movement speed I was moving through the dungeon at ludicrous speed. Faster than any amount of normal speed would be able to achieve since normal speed has diminishing returns after +28 speed. If normal speed did not have diminishing returns +4 movement speed would be said to have @ walking through the dungeon at +50 speed (assuming he had no normal speed boosts), but since normal speed does have diminishing returns +4 movement speed has @ moving at just over +70 speed. Now here's the crazy part: since movement speed is a separate stat to normal speed they work independently of each other (ie. they stack): That's why I thought when my @ had the +4 movement speed sling that the game was suffering a bug, because I was moving and monsters were pretty much just standing still. If @ has + 4 movement speed and +20 speed then @ walks through the dungeon at what effectively would be a speed far greater than an infinite amount of normal speed would let you. So if @ were to walk away from a monster who has normal speed @ would move 15 squares before the chasing monster would move 1 square. If @ was running away from Sauron @ would move 5 squares before Sauron would move 1 square. If @ moved at normal speed but had +2 movement speed and @ was running away from Sauron, then @ and Sauron would move through the dungeon at the same speed. But as soon as @ would take an action (fire a bolt from their wand, shoot a bolt from their heavy crossbow or engage in a round of melee) Sauron is going to follow @'s turn with 3 turns, because Sauron's normal speed is +20 and your normal speed is 0 and you perform one turn of actions in the amount of time Sauron is able to perform three turns of actions (or three turns of movement). tldr: movement speed and normal speed are separate stats, the former only affects @'s speed as @ walks through the dungeon and the other affects both @'s movement and the action @ takes. __________________ Detailed account of my Ironman win here.

Is it really the weight, or the type of armor? (e.g., Partial Plate vs Studded Leather?)

The messages for wearing gauntlets are clear. Follow their example if you decide to change the armor messages.

(But honestly, the vagueness of the messages adds to the mystique...)

That's really useful, thanks!

It's the total weight of the armor. If you put on a heavy shield that puts you over the limit, you may be able to take off your cloak and be under the limit or closer to the limit so you lose less mana. (The further over the limit you are, the more mana you lose.)
