Jumping/stuttering on screen - I do use the client extension. This only seems to happen on the beta server, not the normal servers.
Squall glowing effect - while there was no visible effect at the point where Squall was cast, when characters walked through the area where Squall was active, they seemed to light up with a white sparkling glow. When leaving the area where Squall was cast, the effect disappeared.
Squall description - it does affect spells if the spell needs a ranged touch attack but not all spells.
Corpse explosion - the spell activated, the body it was cast on disappeared but there was no damage done to anyone until Atlantis. I have no idea why it only started working then.
TY for the shards
