for call beast
Code:
<if spell="Call beast">
<equip when="precast" Set="Call Beast">
<ammo>Jug Here</ammo>
</equip>
<castdelay delay="1"/>
</if>
The thing you wanna do with reward is a bit different because spellcast doesn't like to equip weapons in main and sub slot due to the delay for dual wield check in game.
Code:
<if spell="Reward">
<!-- in your reward set only equip 1 of the axes in the main slot Also can add the pet food to the ammo slot -->
<command when="precast">sc set reward; wait 1;input /equip sub "Zoraal Ja's Axe"</command>
<castdelay delay="2"/>
</if>
The above should work for both things
