There are many bugs after the battle sprites updates and re-updates, and re-re-re-re-re-updates.

in this video, we show you some:

Some of them are:

1- Seraphynx Shield can be broken by allies.
2- Drakon Firebolt is casted on your feet if ur close to a wall.
3- Drakon Firestorm doesnt work if your close to a wall.

But some other, not in the video are:

-When heavy-graphic-load sometimes we can see a seraphynx permanent shield.
-Orbs (even the bought ones) cannot be given to your guild chest!!
-Maximizing the time duration of seraphynx shield, DOESNT WORK.
-Drakon Firebolt (this one may be logical) and Firestorm can be blocked by unbreakable boxes, enemy shields (as robots), etc etc

and, maybe the heaviest one:

-SOMETIMES THE BATTLE SPRITES ATTACK AUTOMATICALLY AND CONTINUOUSLY!!!
