So, my party is going to deal with an (over our CR) threat; a large size flier. I think I have preparations set for its specific abilities, but I'm not sure what the best way to prevent it from just flying away once we get it to low health (the fight will probably take place in a large, flat, rocky [difficult terrain] area).
We are...
* 4th Level Wizard
* 4th Level Cleric
* 4th Level Barbarian/Ranger
Are there any good wizard or cleric spells that could be used to shut down its flying? Any mundane gear tricks save for tackling and binding the thing?
