47 Spd => "<b>Speed</b>, how fast you can move. The value of speed may range between nearly 0 (\"very slow\") to higher than 5 (\"lightning fast\"). Base speed is determined from the Dex and modified downward proportionally by the amount of weight carried which exceeds the Max Carry limit. The armour worn also sets the upper limit on speed.",
48 WSp => "<b>Weapon Speed</b>, how many attacks you may make per unit of time (0.120s). Higher values indicate faster attack speed. Current weapon and Dex effect the value of weapon speed.",
