All variable, numeric effects of an empowered spell are increased by one-half.
How do you round this? that is, lets say I empower a spell that deals 1d6 damage. It now deals 1d6 + 1d6/2
I rolled a 6 on the first roll and a 1 on the second roll. This comes out to dealing 6.5 damage. Does it round down to 6 or up to 7?
Or am I supposed to use 1d6 + 1d3? That would actually be on average better results than exactly half.
And what if it is multiple dice. like a 10d6 fireball? do I roll 15d6 then? Or make a second roll of 10d6, add them up, then divide by two (and round up or down)? This method has the issue of uneven dice number. like a 9d6 fireball
