Sorry, my mistake: it said in a few places that party members could share costs during a ritual, and that you'd carry as many ritual components "as you need or can afford" so I thought maybe it was abstracted and the game assumes I already have as many components as I need for any given ritual, up to the amount of gold I'm carrying. However it is probably not so, so I'll take about half my leftover gold as reagents (rounded down to the nearest 10.)
Another mistake: I forgot that being east means I'm in the future. (Thought it was today.
) Noon on Saturday will be 7 in the evening GMT, also still Saturday. That's 2200 at night here and still works fine (especially as it's the Summer Solstice, woohoo!) only I have work the next day so we can have a session up to a few hours.
