Shadow spell question~ Help plz~

[shamana]

I tried to use shadow spell as SC, and the code arre as following:

autoSpell Fire Bolt

useSelf_skill Shadow Spell {
lvl 5
timeout 10
whenStatusInactive Auto Shadow Spell
notWhileSitting 1
}

However, the bot won't cast Shadow Spell, and go on attacking monsters.
Could someone help me with this please.

Thank you.
