I tried your code and tried pasted fragment of code from lursky and it works, but only for me as a player. Problem is beginning when any monster trying to attack me. Then I don't see some spells efect throwing by monsters. For example my Enlightmenet of the Cult:
XML:
<attack name="drunk" interval="2000" chance="10" range="7" target="1" duration="20000">
<attribute key="shootEffect" value="energy"/>
<attribute key="areaEffect" value="teleport" />
</attack>
I see energy shot, but i don't see teleport effect, or spell from other monster - Lost Soul:
XML:
<attack name="speed" interval="2000" chance="10" radius="8" target="0" minspeedchange="-750" maxspeedchange="-700" duration="4000">
<attribute key="areaEffect" value="yellowbubble" />
</attack>
Here I don't see yellow bubble effect everywhere, but I see paralyze condition on myself.
P.S. I use TFS 1.5 downgrade by Nekiro 8.0 and official client Tibia 8.0
