Oh I see now - the calculation is wrong, it's increasing damage by 1d8 per level. Sorry. Change the higher level cast die type to NONE to get rid of that, then put this in the Damage 2 field: [[floor(?{Cast at what level?|2}/2)-1]]d8[Lvl ?{Cast at what level?} slot] and set the Damage 2 Type to Force, or to Upcast if you prefer. If you'd prefer to have the upcast damage just added straight to the normal damage, replace the normal Damage field with: [[floor(?{Cast at what level?|2}/2)]]d8[Lvl ?{Cast at what level?} slot] Unless you really want the drop-down, then just use: ?{Cast at what level?|2,2|4,3|6,4|8,5}d8 in the normal Damage field. There are issues with a few spells that don't follow normal progression or have conditional damage - it's usually not too hard to fix!
