Which is More Likely?
Our adventurers are destined to be great heroes, and have been set three labours to complete. In setting out to re-light the fires of the legendary Mithral Forge, they stumble in to a troglodyte camp in connected cave system. As they fight with some of the troglodytes, the bard tries to improve their situation.
'I'm casting a minor illusion, creating the roar of a lion deeper in to the cave system, to scare these troglodytes and distract them. This will surely gives us the edge in the battle!'
'Or it will just alert other troglodytes further in to the caves that something is happening here.'
