Goal: Make the Cleric class more 'I'm a priest of <insert deity they want to worship>'
Background:
-homebrew setting where Alignment is non-existent
-the world is highly versatile and it is fine for each player to create their own custom deity w/ the following rules (no pre-printed deities exist in world)
Core Approach:
-clerics are now spontaneous casters
-when selecting domains, the cleric must select 3 domains. One must be selected as Primary, one as Secondary, and one as Tertiary.
-the spells for these domains comprise the cleric's available spell list
-the cleric does not gain the Domain Powers for the tertiary domain
-the cleric gains +1 spell/spell level on top of what is already listed in the base clerics spell progression
-the 'domain spell' slot can ONLY be used for the Primary Domain spell
-all spell cast from the Primary Domain spell list are treated as though the effective caster level was +1 higher
-option at level 1 to choose to (a) retain Armor Proficiency: Medium & Shield Proficiency OR (b) lose them, but gain any Channel bonus feat of their choice
Options On Top Of That (I'm not sure what of these might result in the best balance):
-for the purposes of casting Primary Domain spells only, the cleric can act as though they have access to all metamagic feats (does not negate the increase of spell slot for use of metamagic feats)
-add 1 additional Secondary Domain (extra spell list, extra domain power)
-add 1-2 additional Tertiary Domains (extra spell list, no extra domain power)
-remove channeling, but gain +1-2 spells/level
-add an extra bonus feat every X (4?5?6?) levels -- this feat must be a Channel Feat
Target Result:
-priest who can really only summon divine powers appropriate for the deity they worship
Much thanks ahead of time!
