Edit: Nevermind the part about Oracle, I mixed up Counter Spell and Prophecy.
Also Paladin only benefits Inquisitor with Conviction. And it only increases the damage of Godsmash at this rank (hopefully something else next rank, Paladin still feels very lackluster, Inquisitor must fix the class
). You currently don’t have Godsmash planned in and somewhat rightly so since you plan on going for con, int, spr and not for dex (no crits => kind of weak godsmash).
For an int build you may as well skip Inquisitor and go for PD 2 instead. Your friends may or may not miss the inquisitor wheel and the malleus debuff but this will allow you to deal good damage by yourself.
By the way, spr is sort of useless. Barrier slightly benefits from it and to a probably very small degree also Turn Undead but literally nothing else in your build. It’s not worth it to put points in there just for that.
People usually just go for spr if they want priest 3 for Stoneskin. And then they consequently become chaplains.
Smite and Conviction by themselves are very weak lategame. Would really hurt to not have Godsmash to make up a bit for it. But like I said… no dex, no crits, sucky dmg. And if you go dex your healing will be garbage, even with the hidden bonus from Restoration.
Also, some point distributions don’t make sense to me. Why 4 points in Cure and 5 in Restoration? 1 point in Restoration is enough to get the hidden healing bonus, 3 for the attribute (which is quite expensive to max out and not very useful overall). 5 does not make sense. Cure is a somewhat strong damage skill for int builds because of the multihits. Either go for as much as possible as a damage skill or leave it 1 for the debuff removal. Points could be taken out from Fade (1 is enough, though the duration from 5 feels good and always makes me happy personally
).
Also… Barrier does not keep large type enemies out. They just walk right through and usually hurt a lot. The whole “Protection Zone” thing may not work as you imagine it. Barrier scrolls can also be used by anyone btw. Pala sadly does not even have a monopoly on the skill.
As for other useful support class options:
Priest 2 for Mass Heal & Revive
Cleric 3 for the max amount of healing tiles
Kabba is for Ein Sof only (restores SP fully with attribute and the HP increase is also welcome - difficult to help other party members with it though because they have to step on it and usually nobody sees it)
