How To Lock Af Feet During Mana Wall

I have <equip when="AfterCast" set="idle" /> rule, i need something to lock feet when buff on and go back to idle aftercast when wall goes off.

<if buffactive="manawall">
<equip when"aftercast" set="idle">
<feet lock="yes">Feet Name</feet>
</equip>
</if>

<if Notbuffactive="manawall">
<equip when="aftercast" set="idle" />
</if>

That should work I think... the buff name might be wrong.

<if buffactive="Mana Wall"><equip when="idle"><feet lock="true">Goetia Sabots +2</feet></equip></if>

Should work too with less space?

Thx.

<if mode="or" buffactive="Mana Wall" spell="Mana Wall">
<equip when="precast|midcast|aftercast">
<feet lock="true">Goetia Sabots +2</feet>
</equip>
</if>

If I remember right, the boots have to stay on for the whole duration for the ability. If you take them off, you can't put them back on to regain the bonus. This will lock them in place.
