Is there an attribute on the NPC sheet that is the sum of proficiency and stat bonuses for skills? I see four different attributes for perception: perception_roll: @{wtype}&{template:simple} {{rname=^{perception-u}}} {{mod=@{perception_bonus}}} {{r1=[[@{d20}+@{perception_bonus}[Mods]@{pbd_safe}]]}} @{advantagetoggle}+@{perception_bonus}[Mods]@{pbd_safe}]]}} {{global=@{global_skill_mod}}} @{charname_output} How do i use that attribute? Is it useful in macros or something? Is there a button on the NPC sheet that rolls perception? npc_perception_base: shows whatever i type in the "Perception:___" entry on the NPC sheet. if I type "+6", then that is shown the same way here. Is this meant to be a toggle? Is it meant to reflect the total of all bonuses the NPC has for Perception? Should I put a "+", or just the number? Should the number be the bonus due only to proficiency? perception_bonus: seems to be automatically updated to reflect the wisdom stat How do i use this? npc_perception_flag is set to 2, but I can't figure out why. It looks like if I leave the "Perception:___" entry spot empty or enter a letter in there, this attribute is "0", but if I have any numeric value in the "Perception:___" entry spot , including a "+" or not, then this attribute becomes a "2". What does this value mean? Is it an index or toggle? Is it used anywhere? Can I use it in a macro? npc_perception seems to remove non-numeric values from the npc_perception_base, so if I type "+6" in the "Perception:___" entry spot on the NPC sheet, this will just be "6" What is this for?
