Looking for rules on how to run a semi sentient Arcane Ballista that can be used as a monster and equipment. Any ideas where I can find rules for this or does someone have rules they can share?
Dungeon Magazine 155 published an arcane ballista. It's level 6, but easily adjustable to 5.
While no rules are published for capturing this an turning to your side, I'd imagine following similar rules to beast taming would be fair game (just sub arcana checks for nature checks).
