Re: Thoughts: Pathfinder healers- How to be more than a healbot?
Wands-are-your-friend. Keep some potions on you, just couple, in case you're eliminated, and stock into scrolls of fun spells but ones that don't require save. 1st level spells can be afforded right off the adventurer's train-station to gravy (mostly the muddy kind). If you want to, say, have the ability to bless alot, prepare it, you can get heals with that. Otherwise? get a scroll. Most combats are decided in ten rounds and it's just damage control and going through the plan, or running away.
If you're higher level, even 3rd, stock in a cure light wand, seriously you'll be surprised at how well they help. They may seem a waste later, but out of combat it's always useful, your team will eat it and like it.
Prepare spells that are often useful for the campaign. If you have a lot of things that cast fear effects, get remove fear, sure, otherwise get divine favor (if you plan to fight as a hiccup rather than ready) or something that will be useful in a common vector. I haven't played much pathfinder, honestly, but I know it's got to be easier to heal and do other stuff as cleric.
My cleric in LG (Living greyhawk) casta heal in combat six times, period. Otherwise it was prayer, bless, shield of faith, and so on. I had wands in between rooms. Potions for when I fell that were specifically for me. I had a 16 strength from being a wood elf and 16 wisdom. I mostly fought though, would bull's strength and then wade into combat. could I tank? Sure, give me a shield of faith and I'll fight defensively under prayer or doom. Can I do damage? sure, just a divine favor, bull's strength and a little power attack. Am I fighter? no. Am I a mage? no. Do I heal? Of course, but that's not my job, that's coin in my purse. That's not what spells I prepare and use often.
If you're using cures to keep your allies alive you're making beds in burning house. You need to drop buffs and have scroll for "Oh great, it paralyzes. Oh well, that's why I have remove paralysis scrolls" pr "oh, it's poison. Dang. Well, here goes my delay poison scroll. If this lasts an hour I think I'll make back my money on the bet for longest battle". Don't prepare all healing spells, and yes, even "remove this crap debuff" spells. Use your preapred spells to supplement a reserve. Does it require a save? Does it need to be of your CL? If not, buy a scroll.
Cures should be wands though, not scrolls. Have a wand in your shield hand and choose wisely which strength it is. I had a wand disarmed in critical battle the dang death priest healed himself with it. You don't want to be grappled and have to draw a scroll, that's just doom right there.
Also, help be leader, call out tactics to your team ina shared language. If you're fighting dragon, make it something other than draconic. Talk it out, in game. "Hey Rogue, flank the ogre and fight defensively. I'll be on the Hulk's side making sure he doesn't stop putting the pressure on the ogre, and is the main threat. The wolverine can help you if you need it." that may take ten seconds of talking, so two rounds, but most likely you can start the process.
In my first play in Kingmaker I was fighter but was the tactician. Our cleric was like you said, but often times was targeted and so had to heal herself. WE smoked even the levels 6's (two of them) just by using tactics. That was an EL 8 at level 3, and we smoked it.
Bottom line, don;t play healer, play a cleric. A fighter has his choice weapon, can he use a bow with strength mod, sure, yeah, but should he, of course not. Healing is a fallback, prevention like AC and saves lasts over time. Feel free to wade into melee with your 14 strength, or fire pot shots with your crossbow, or just use spells like doom and command to make your foe just give up in humiliation. Have fun! You don't want to be healbot. Don't be. Let your allied fall, or get bad off and then drop a big scroll and take that chance you might roll a 1 to 3 for a spell beyond your normal level. If someone dies? Well, then you learn. Pool together your gold and see about reviving him, if not, you have about 130 years before the resurrection will be invalid. That's assuming someone doesn't just want to make new character.
Healing is not necessity. I play in an all cleric group (of D&D mind you) and none of us have healed, not even ourselves. Clerics galore, but no, we don't heal. We don't need to. And we're not twinked out here.
So consider it. Scrolls seem like trash loot, and they can be, but you'd be surprised at how much more fun it is to just drop a flame strike or greater command frivolously when people really want you to have the raise dead, just in case. Screw that! Get a scroll.
