In the past, you needed the snail shells. However, right now, all you need to do is double click the skill in the skill menu or assign it to a hotkey and press it.
Like how you would use any other attack/skill.
Use the normal attack button given in your default keyboard.
Yes, normal attack, bandits can't use red whip with skills.
you have to use a skill in your skillbook (K) the dragon is not made to be attacking with melee
I the maps near Korean Folk Town, you will see plants around where the monsters spawn, use normal attack on them to break them and the plants will drop.
Double clicking the item in your use inventory generaly will work. To open your use inventory, click "i" and if clicking i doesn't work, then that means you changed it, and you will have to click the bag looking icon at the bottom right of your screen. Then click the "use" tab of the inventory. The double click the item you would like to use.
You dont
I'm guessing you have an evan. So, open up you skills tab (k) and your hotkeys tab (\) and drag magic attack from your skills tab onto what ever key you want it to be on the keyboard.
Cause in real maplestory you can show it off to all the noobs. lol.
Crossbows.
