help on what stat to put on
/20/20/20
depends on plans for the build, if you plan to actually use meltsis 0 spr with a mix of int/con, otherwise decent spr/int with enough con to survive to improve priest abilities.
you can also sub some parts of your planned path for other classes to improve damage as r8 has a lot of power in it.
Simply not enough info to go off of here
