Eating/Smoking in battle - now THAT is something that has always bugged me. Not that it can be done, but that it can be done with 0 lag penalty. In my opinion, smoking an herb or eating a pill should be a 2-round lag. Think about it, kicking dirt in reality takes two seconds...smoking something takes a LOT longer.
What if we made consumables 'labored actions' and/or 'delayed effects'? We could create parameters for consumables, like instantaneous, labored and delayed.
instantaneous action/effect: an action and effect that takes place without difficulty or delay. (zapping with a wand could be one such instantaneous effect.)
labored action: an action that requires a degree of effort and focus; actions that require time to perform. (eating, quaffing, smoking could be considered labored actions... which means, when a character tries to perform one of these labored actions they'll be 'lagged' while exhibiting a set number of emotes... that effectively is the character carrying out their labored action.)
delayed effects: conditions that are not spontaneous. (pills, scrolls, staves could be considered delayed effects... which means, it takes a bit of time before the 'magic' of the item will effect the character. the character isn't lagged.)
any number of consumables could fit one or two of these categories. (e.g. reading a certain scroll could be considered a labored action with a delayed effect... since the character has to read a magic scroll and wait for the magic to take effect.) -scrolls that have multiple spells might be considered labored where a scroll that only has a single spell would be an instantaneous action but still a delayed effect considering the amount of magic being accumulated and released by the scroll- -a scroll with a single low level spell could be instantaneous in both action and effect-
[i'm just spit-balling. Mmm Beer's post made me think of this. what consumables should be considered under my parameters (or another's if they feel like adding to mine or creating their own) are entirely up for debate. how long a particular consumable should lag/be delayed is also up for debate.]
