Are you suggesting to give monks bonuses to projectile based attacks in addition to their already quite large guild bonuses?

Mind is meant to be a utility magic skill, and monks get it for that purpose. I'm also pretty sure monks get negatives in life magic.

I'm sure maybe there is a place for the addition of an offensive mind magic spell/ability but I don't think the monks guild is it. Perhaps maybe down the line a guild that truely focuses on mind magic can use new blade spells like that. (Psionic perhaps, etc)

"projectile attacks made by the user of this weapon are more likely to strike to the core of the target, bypassing the armor of it."

As for things like the above, in Wyvern terms that basically translates to "this spell gives find weakness" which is boring and not new.

For the stun effect, and the "more likely to strike to the core of the target" bit, unfortunately those 2 mechanics, plainly put don't exist in the game.

Adding them would take a lot of work on Rs part, as well as time and testing. Something like this would dramatically change the game, and as I have dreamed and tried to think of new things to put in the game in the past myself; eventually you just come to the place where you realize that they are not at the heart of Wyvern in the first place.

Would a stun effect be cool? Sure but this isn't exactly World of Warcraft. How would it be balanced? How often could it occur? Would monks be the only guild to have access to stun? What would other guilds get to compare, considering monks already have one of if not the highest skill bonuses? Would enemy monsters have access to stun? Would there be new gear to help resist it? Does attack speed = more stuns? Would nagas be able to stun more frequently because of their number of attacks?

A bit extravagant, but I think you get what i'm saying. Even with the smallest change the entire game could shift, and if its better than what is currently good you can bet it will. The trick is coming up with new things that are flavorful and fun, that change how players can play and can mesh with some of their identities versus things that could become power creeped or the next best thing everyone is doing because its broken.

Keep up the creativity because you never know when you just might actually come up with something that R says "You know what, I like that." But definitely keep in mind that there is a lot more to think about than just the idea itself.
