75% increase to scroll healing when splashing 1 level of cleric or 2 levels of artificer. Maybe for rogues too. This makes it very interesting to splash into one of these directions.
It's fun how this enhancement pass makes room for new interesting builds already.
The cost of 1 AP per tier for cleric is ridiculous though. Needs to be 2 AP per tier. For artificer you need to spend 6 as well.
