I realize how broad and subjective the title sounds, but it's the most honest and straight-forward way of asking the question I need answered. About a year and a half ago I joined a Pathfinder group who needed a cleric after the last one left, and decided to make a Dwarven Priest of Grundinnar. I stumbled a bit, but I managed to contribute to the team, thanks to all of my ability mods being at least +2. We even managed to get from level 3 to level 5. However, we took a few months off early this year and I managed to loose my character sheet. Naturally, I had to re-roll using the 4 dice system (like when we started), which is where my problems began.
My new rolls were 15, 16, 13, 10, 9 and 8; considering that I was a Dwarven Cleric, I needed to mitigate the reduction to my Charisma (additional uses of channel energy and domain abilities), so I put the 16, ergo 14, into that. Up into that point, my character had caused some problems with a lack of foresight, so I felt that I needed extra points to keep my Perception and Sense Motive up on top of KnReligion in order to qualify for Quick Healing; 13 went into that. Naturally, I put the 15 into Wisdom and the 10 into Constitution, there was no way that I'd play a character with no health or unable to use their spells. So that left the 9 to go into Dexterity (bumped up to 10 from lvl4) and the 8 to go into Strength.
While this sounds all well and good, Let's take a good look at the rest of my party. First and foremost, there is the Rogue. Human that started with 20 Dexterity and still impressive numbers in his other stats (I never looked at his sheet, but he is usually the big mover in our group). Over the adventure, he had honed his craft and collected a few key items that maximized what he could accomplish with his bow. Right now, he can take constant Called Shots and almost never miss. Then there is the Magus. Her deal is that she has the spell power AND the Brawn to wreak your average shmuck in about 1 to 3 blows. While this is just about how most people play Magus, the guy playing her just recently gained Sacred Geometry with the Quicken and Maximize metamagic feats, enabling her to wreak most creatures our APL with a single cast. And then there's the Bard, a frickin' maniac that replaced our brooding Ninja that fixes as many problems as they make. However, despite the constant messing up, he is just about indispensable with his whip mastery (to help him trip things) and his Bardic Songs buffing everyone.
Now let's get back to me for a moment. I am currently lvl 6, have the Extra Channel, Selective Channel and Quick Channel feats and am a practical cripple compared to my party members and the enemies we face. The ranger hits everything without a problem; I have only landed three hits with my regular war hammer over the last two months, and each of them dealt 1 NON-LETHAL damage. The Magus put an Ettin half in its grave with a single attack; I casted 3 Spiritual Weapons and chipped away at a thug in the streets over seven rounds. And before you say that I still have buffs and debuffs, the Bard outclasses me in buffing and my spell DCs don't exceed 16 while the bad save for something reasonable to be thrown against us is between 3 and 5. It doesn't feel like I'm a very strong spellcaster when most of my spells have a 50% chance to work at best. Nor do I feel solid when a child could suplex me with a CMD of 13.
I know that my build is technically better than a High Fantasy character and spells like Spiritual Weapon, Admonishing Ray and Greater Stunning Barrier do feel good to use, each of these spells have had dubious results when I used them and all of my other spells and abilities are pretty much rendered moot by my other party members (the Bard practically replaces me with his constant purchases of Cure Wound potions, which has happened since he joined). At this point, you could make a wondrous item with 5 uses of cure moderate wounds and that would probably be just as effective as I am. I brought up these issues I had with the DM and he told me to look into ways to increase my Wisdom Mod outside of naturally leveling. Each of the ways I found (Ioun Stones, Headbands and Books) are well outside of my price range considering that the majority of the hordes we find are taken up by singular magic items.
It has honestly become really depressing playing a character that can run as fast as everyone else for 18 seconds, change the spells that almost never hit to deal non-lethal damage, and a 1,000GP extra CL1 Spell Slot. So since it is so difficult to buy better stats or not die in a few rounds despite having 42 health, how can I play this character better?
