Chaincast Adv Magic/Normal Bolts

you can walk/run with it, cast without a wand, etc. And in the case of Fireball the damage is the same since it is calculated as a full, castable fireball (the charges of Fireball dont appear to have individual damage cases). That's to the best of my knowledge.
theoretically, anything that has a field modifiable by the skills xml (skill locks, movement locks, requirements, stacks etc.) Unless its currently locked, or checked by the server. I do know at one point it was possible to use adv magic without a wand and run around with it charged... not sure if its been patched though. Haven't tried again.

I bet the notorious UG have such a mod.

I blame Kou for our access being withheld?

I would love to be able to charge Thunder without a Crystal lightning wand...I would use a -45% Mp usage Tikka healing wand, it would help a lot with potion costs

This is possible and has been done. They can use the fireball skill once and it'll load all 5 charges in one go. It's a pleione dll edit though i think, can't quite remember.
