Is it sure the pen is non rechargeable?
As copying runebooks with a 100% Lower Reagents Suit just costs time and the runes.
Why would anyone buy the pen then if it costs $ when with a little more time youcan make it even ingame almost free?
100% sure, no... but unlike the house tiles that explain a recharge procedure, the pen only says it loses one charge per use.
I can see it being useful for guilds that hand out runebooks to guildies, vendors who sell various point of interest books, and organizations that hand out event books... I mean, honestly, it's a time saver... you only need to make the initial book once, and then whammo, copy it.
But... at only 100 charges, and no recharge (that I'm aware of), it's a money-sink I'm not ready to sink any money into. hehe
