Vindictus is quite an interesting game. Post your interesting observations here!
To start:
1.If you slip dash/roll/sidestep/anything with forward momentum off an edge, you'll shoot out pretty far. If you hit a wall you can prevent fall damage some of the time. You can also use this to stand on top of other objects that you can't get to otherwise, like rocks and the fish box on the fishing boat.
2. The ice stalagmites (on the ground, they MIGHT reach the ceiling) in Dethrone the White Tyrant are weaker than normal ice stalagmites. I think they did this to exaggerate the polar bear's strength :O Also, ice stalagmites sometimes drop the ever so rare ice crystal.
3. You can play without a weapon. You can't sprint (though it costs stamina to try) or roll and you can only punch using your regular attack. You move so slowly, in fact, that if you pick up a light object like a pot you'll run faster :O
4. You can damage and kill your teammates using the environment and secondary weapons. Some of the more imaginative and hardcore players use this to farm Seals.
5. Halloween candy isn't considered to be a potion. This means you can take it on no-potion oaths of honor :)
