I didn't know where to post this... There seems to be a bug with the auto-kick system. If a guardian successfully blocks a bracelets M2 he gets kicked. It happened several times, the guardians I fight just disappear after a successful block.
This has nothing to do with bracelets, it has to do with a bug in cubeworld where your charged mana goes negative if you block and i kick for that..
Well, that's not a big deal. I don't think anyone will be upset about not being able to only use shield. I understand it's a bug, but small. This is assuming you mean while wearing only a shield.
It is significant actually. You can't block shuriken from rogues allow a really easy burst down of a defensive class.
