Sure thing! Welcome to the forums, so the weapon mods like 11^50 and 14^50 aren't salvageable, so they don't really have a seperate value, and the same goes for any shield mods, though of course having such mods on weapons along with Charr mods, health, and damage reduction on shields will increase their prices, it changes the price based on the rest of the weapons stats so it's hard to price them individually as mods.
price updates due to the market being so lively as of late also updated the staff notation to: "*Charrslaying Mods on Staves only affect the damage of automatic staff attacks. (not spells)"
Side note: if you disagree with prices seen above please leave a note below or message me I'd like to keep this update however when change to the market happens in pre, it hits hard and some things are missed, thank you all for working with us to make our market a more honest and better place.
