BP said: You need to use the Shaped Companion script to auto-decrement uses. Hi :) thanks for getting back to me. I am using the script, it's up to date, and 'Automatically use ammo' is turned on. I've tried several ways - auto-populating weapons from the Compendium, adding them in myself, creating a new character sheet and trying it on that, tried with all four characters I'm attempting to use - but I always get the error on the API Output Console of "No ammo attribute found corresponding to name XX" (where XX is whatever ammo that weapon uses). Everything else decrements just fine - class and racial effects, hit dice, spell slots - but ammo isn't. It does do the maths in the chat window: " 10 to hit, range150/600 ft., 24 Arrows" (where the previous amount was 25, it's correctly decremented it to 24), but doesn't actually decrement the ammo count, meaning that every time I activate the attack it says 24 arrows left. I've googled that specific error message and gotten two threads on this forum, but both of them say they're resolved by updating the script. I manually added the script yesterday, as per the installation instructions, so I don't think it can be that. Thanks!
