Make an Autocast spell not autocast

[qbz23]

Uh, i need a DoT spell, and the only spells i know of that i can base it on are shadow strike and poison arrows... The unit already has a spell based on shadow strike, and poison arrows is autocast.... so any ideas? Either to make poison arrows not autocast, have multiple spells based on the same spell in the same unit, or another spell that has a DoT effect? Thanks

Use Slow Poison instead or Poison Sting, which are passive.

Or use Doom, or Wrath (not sure about the name, but the one that Firelord has normally, which also reduces damage and some other stuff)
