The easy to get commondation BP for the 10% reduction in sp cost is nice but often sp is plentiful.
The Fallen Leaves for 50% exceptional fortification in particular seems hard to get elsewhere.
The new dragon one with major lore looks nice but lores can be found elsewhere in particular if you are weapon swapping.
The new dragon one with 50hp is nice as more hp is always great.
What do you think?
