Hi, I've pretty new to roll20 and very new to the APIs. I've been following Nick Olivo's youtube videos and learning a lot. In particular I'm trying to setup a new spell cast ability that rolls attack, damage, and plays both a sound effect and visual effect. I've copied Nick's example but I cannot get the vfx command to show anything. Any advice? Here's my version... The attack roll, check against AC, damage, and sound effect all work as expected. The vfx line gives me nothing. Help! !power {{ --name|Eldritch Blast --leftsub|Ranged Spell Attack --rightsub|120 ft Range --Attack:|[[ [$Atk] 1d20 + @{spell_attack_bonus} ]] vs AC @{target|AC} --?? $Atk >= @{target|AC} ?? Damage:|[[ [$Dmg] 1d10 ]] --soundfx|_audio,play,nomenu|EldritchBlast-sfx --vfx_opt|@{selected|token_id} @{target|token_id} beam-frost }} cheers Phil
